Richard’s MR2 Turbo: Not Too Pretty To Pirouette

It began all the way back in grade school with Gran Turismo. A few years later, Richard Tran graduated from video games and started moving through the worlds of hard-parking BMWs and drag racing until his expanding network brought a few road racers into his life.

When they invited him to a track day with Speed SF in 2019, he accepted — but not before considering the consequences. Richard was opposed to taking big risks; he’d seriously hurt himself in a car crash a few years before, and he certainly didn’t want to damage his then-new M3, but they persisted — they told him he’d leave the the track feeling something extraordinary.

The feelings of euphoria following that first session helped him forget about the potential costs of thrill seeking. In fact, he’d been bitten badly enough to sign up then and there for another twelve track days. Quickly, he put the dependable M3 on the back burner; he had a cheaper, lighter, more maneuverable mid-engined car he believed would take more to master.

To the trained eye, his 1991 Toyota MR2 Turbo (SW20) didn’t look like the ideal track toy candidate. Actually, it looked more like a museum piece. Three-stage paint, fresh interior panels, and completely new suspension components were all parts of a three-year restoration that culminated in a show-grade vehicle. Richard was so proud of it, he displayed it at SEMA.

Work Meisters and the OEM kouki aero was all that was needed to make the SW20 pop — it truly is a svelte, sexy car.

Despite its immaculate condition, he felt it wasn’t too good to be used in the way he’d (ab)used his M3. In fact, Richard felt that he’d be missing out on something vital if he didn’t track it. There was a directness and a demanding quality about it that made him feel giddy at 5/10ths.

The second outing proved he had his head screwed on straight, but didn’t quite have the quick hands needed to manage the MR2. The factory components just wouldn’t cut it, especially on all-seasons, so he replaced the rotors with slotted Stoptechs and slapped on a set of EBC Yellows. Along with those, he installed a set of Tein Super Street coilovers, a pair of GReddy side skirts, and a 1998-spec spoiler with lifted risers for a little flash.

The basic package was fun, but far from friendly. “I made the mistake of trying to drive it like the M3,” he began, “and that just wouldn’t work. I learned pretty quickly that I couldn’t throw it around or brake as late as I could in the BMW.”

The odd agricultural excursion didn’t dampen his enthusiasm for his demanding new car.

After many red flags and several stern conversations with the track workers, Richard learned he had to soften his inputs a little and improve the chassis a lot. The second-generation MR2 is known as a nervous car prone to rotate without much provocation, but it can be tamed with some suspension work, a little maintenance throttle, and the right sort of staggered tire setup.

Giving precedence to the rear axle began by fitting the rear wheels with 245/40R17 Federal RS-RR Pros — somewhat wider than the 215/40R17 fronts. Then, Richard turned to Elite Performance’s Melody Cannizzaro to soften the sensitive midship’s edges. A little more front camber relative to the rear helped settle the rear end while cornering, and more toe-in at the rear kept it planted under braking and acceleration. Then, as advised by his friends, Richard tried stiffening the front to minimize the nose dive under heavy braking, which could encourage the lightened rear to spin.

Minimizing some of that see-sawing gave him much more confidence in the car, and the resulting improvements in cornering speeds helped Richard notice a few more of its shortcomings.

It wasn’t the tight, direct thing he thought a lightweight MR car would be, but, after all, it was nearing a half-million miles. Sunshine Auto overhauled the entire suspension, adding new control arms, bigger sway bars, inner and outer tie rods, additional chassis bracing, and a set of 808 Racespec coilovers from Bob Pham. “The new setup made the car feel like a go-kart. Actually, the first day back at the track with these mods, I went six seconds faster than I’d ever gone before,” he exclaimed.

Richard’s love for the Sailor Moon series gave this car its eponymous nickname.

“Those modifications transformed it from a decent daily driver to an uncomfortable track car, but I still trust it enough to drive it to the track — it hasn’t left me stranded once,” he said. Pretty impressive for a car that just passed the 500,000 miles on the odometer. Chalk a bit of that up to build quality from the late-eighties Japanese boom, some of that to Richard’s obsessive maintenance habits, and a little bit to the near-stock configuration of the power train.

Aside from a Mishimoto radiator an HKS SSQV BOV, and a Berk 3” exhaust, the original 3SGTE motor remains stock.

Aside from a splitter and a pair of canards, Richard doesn’t plan on adding much more. Actually, he’s confident enough to admit he’s the limiting factor at this stage. “My friends will get in and go six seconds faster than I can, so I know I need seat time more than anything. Well, I could use a set of Sparco Circuits because I’m getting thrown around on the stock seats, but that’s about it.

For me, it’s the perfect track car — dependable, fun, and constantly challenging. I don’t really care about making it the fastest car here. I’ve got a ways to go as a driver, anyways. I’m not here to be the best — I just want to have fun, and in that department, the MR2 always delivers.

My track friends’ words of encouragement and support have been a driving force behind my journey; pushing me to overcome obstacles and strive for greatness. I rolled my car once many years ago and I was in the hospital for months. I thought I wouldn’t walk again.

My wife did not want to see me in another accident ever again. Actually, she wanted me to retire, but she saw how happy I was attending track days with friends, so she now watches me track. I promised her I’ll never go completely flat-out ever again and I’m fine with that — as long as I get to see her smile.”

Brian's BRZ: Painful Lessons in Lubrication

He’d spent years dreaming of driving on a track. Brian Armstrong had grown up hearing racing tales from his late uncle, a former professional stock car racer; and grandfather, a racer, mechanic, and performance engine builder. Even coming from good stock, Brian hadn’t really found a door into the world of motorsport himself. The opportunity finally arose when he relocated from New York City back to his native California in 2021.

Now in a more car-friendly environment, he decided to get a more track-oriented car and explore performance driving. It didn’t take long to choose a vehicle. He wanted a front-engine, rear wheel-drive platform and relatively low cost of operation. It was either the newly released BRZ/GR86 or the latest MX-5. The stars aligned when he found a 2022 BRZ in World Rally Blue in transit to a local dealer for MSRP. He put down a reservation site unseen and picked it up about a week later, in early December 2021.

In Good Company

He started with autocross, attending 4-5 events before graduating to track days. After a couple events, he found 86 Challenge, a local time attack series dedicated to the 86 platform and sponsored by SpeedSF and GT Radial. He started participating in the Stock Class, which allows only minimal modifications to the car, with the intention of setting a level playing field with a low cost of entry to be competitive. “The stock class appealed to me because all the cars are set up the same, more or less. That means your pace is primarily dictated by driver skill.”

The few modifications allowed in street class help showcase the BRZ’s brilliance out of the box; there are no drawbacks to having such a short list of legal upgrades. His car has the following modifications:

• Pedders Offset strut mounts and top camber bolts for -2.5° of front camber

• 17x8” 949 Racing 6UL wheels wrapped in 225/45R17 GT Radial Champiro SX2 tires

• AP Racing Endurance front BBK with Ferodo DS1.11 pads and Carbotech XP10 pads in the rear

• 7mm Perrin front spacers

• ARP extended studs

• GR Performance Exhaust

And he’s added a couple ergonomic tweaks: a shift knob from Ansix and, for a little added support, he inserted a section of half-inch yoga mat into the factory seat bolsters. It’s surprisingly effective!

In addition to competition, he also found community in 86 Challenge. Having faster drivers as benchmarks is helpful, but the participants also freely share information to help each other improve as drivers.“We record our telemetry data on AiM Solo 2 or RaceChrono data loggers, then share the data on Google Drive, so we can compare. It’s all voluntary, but we all want to help each other get faster.”

They were also interested in diagnosing some of the BRZ’s from-factory flaws. “We’ve also been collaborators in trying to understand and improve the reliability of the oiling system in the 2nd generation BRZ/GR86,” Brian continued. Two 86 Challenge participants had added oil pressure sensors to their cars and started documenting oil pressure drops on right hand corners as early as November 2022. After several drivers in the broader 86 community suffered engine failures on unmodified engines, including a couple who Brian knows personally, this became a bigger focus..

Brian’s analytical strengths helped him delve into the data and contribute to this effort. He instrumented his own car, with help from 86 Challenge drivers @nostreetracing86 and Miles Kodama, and published a video on YouTube explaining the issue with evidence from his car and two others. He also volunteered to test a prototype baffle from Killer B Motorsport and later Verus Engineering in hopes of finding a simple way to mitigate oil starvation.

Ironically, his engine blew the day one in-depth article he’d contributed to was published.

That expensive afternoon at Thunderhill East went smoothly until it didn’t. Initially, when Brian saw a pressure drop to 0 PSI, he first thought a sensor had failed. When he heard that terrible telltale shuddering sound emanating from his engine bay — the one he’d heard so many times in the big-hit failure videos on YouTube — he knew it was catastrophic.

Thankfully, fellow 86 Challenge driver Kevin Schweigert offered Brian space in his garage to suss out the cause of his FA24’s failure. With the pan on Kevin’s garage floor, Brian took a peek. It took two seconds to determine what had happened.

A small piece of metal had broken off the baffle and blocked the oil pickup. “It was a one-of-one prototype build, so these types of things can happen. Verus immediately accepted responsibility and said they would help with the rebuild.” They covered the cost of a new FA24 long block and, through generous donations from the community, Brian was able to cover the cost of labor and additional parts needed for the rebuild.

Second Stab

During this rebuild, Brian took advantage of the opportunity to make some improvements to his oiling system to try and increase durability and decrease flow restrictions, which can decrease pressure to the crankshaft.

His old oil cooler lines had been rubbing on a sheetmetal seam near the driver’s side headlight and there was insufficient protection from abrasion. It could have been a serious issue if not addressed.

Following advice from other 86 Challenge members, he decided to replace the lines with custom built Goodridge 910 AN hoses—as used in the GR86 Cup Car. These kevlar-braided lines are more abrasion resistant, but also feature a larger internal diameter, for less flow restriction. He also increased the size of the oil cooler core with the hope of reducing temps and reducing flow restriction.

His shakedown of the new engine, oil cooler, and a new generation of oil pressure instrumentation hardware at a recent SpeedSF event was auspicious. Everything worked well, Brian was at ease, so he pushed a little harder than normal set a new PB.

Brian’s committed to the cause. His continuing work with Verus aims to solve this starvation issue and the pair is planning to test a new prototype in January. They now believe the primary issue may be related to the oil returning too slowly from the heads to the oil pan, which the prototype attempts to fix.

The community support and innovation from the major aftermarket players have encouraged Brian to continue chancing his baby in an attempt to solve the problem which worries most BRZ owners. Undaunted by the big bang this year, he’s planning on returning to Stock class in the 86 Challenge in 2024. Consider it a testament to a lovely atmosphere among cooperative drivers and an exhilarating platform worth taking a few risks for.

Tailai's Supra: Keep it Simple, Keep it Sane

Started tracking in 2018 after moving to the States to study at UC Davis. Being an undergrad student, Tailai time was booked solid. Even so, he had an image of Sonoma Raceway, an image he’d had in his mind since playing Gran Turismo in his early teens, and he knew he’d have to find a way to experience it.

With no real knowledge of the trackday landscape, he booked a three-day advanced driving course at the Simraceway Performance Driving Center, where he was able sample the circuit and the strengths of his daily, an E92 M3. “I didn’t know anything then, so I kept the stock pads and went to drive. The only thing I added was a big wing, because it was cool.

The car was stable and forgiving, and the classes went off without a hitch. The subsequent visits to the track weren’t always failure-free, though. “Whenever I tried to push, something broke.” He endured the bills and, without much of a racing education, he started modding the car to make more power — something entirely predictable. He slapped on a VF supercharger and, after it was installed incorrectly, he blew the motor.

Disappointed, he sought out something reliable with more tuning potential. He didn’t like how American cars drove, so no Camaro. The atmospheric BMW engines weren’t all that interesting to him, but the potential of some of the turbo cars caught his eye.

“I first bought the Verus full aero, which I now see was foolish. I should’ve started with suspension, but the aero kit was too cool to ignore,” he laughed.

He didn’t exactly settle on another car from the same marque, but he wasn’t far off. After finding an impressive deal on a 2021 Supra, he pulled the trigger.

The first outing in it, he left it completely stock. Very capable already—capable of lapping Sonoma in the 1:53s. By this time, he’d started studying what would keep his ass in the seat and what would drop times the fastest.” I wanted the car to be reliable, so I didn’t touch the powerplant. There were more important things to change.”

Maybe the pleasure of seeing the car kitted out was the right move, because it wouldn’t let him down like his first set of coilovers would. The first set of KW Clubsports broke after a few days. Fortunately, his growing social media presence helped him secure a more track-oriented setup; KW reached out and offered him a set of Competition coilovers.

Then, seeing how easily he was squeezing noticeable performance from the package, he got a little smarter with his tuning approach. He hit the books hard and called on his years of building soccer robots for RoboCup Junior. With his analytical mind whirring away, Tailai could not ignore the way Supra’s weight was working against him. “Weight savings starts out cheap, but it gets pricey pretty quickly,” he admitted. Just by pulling the carpets, seats, adding a cheap Chinese fiberglass hood, and changing the battery, he trimmed an impressive 200 pounds from the car, and only spent an afternoon a few hundred dollars.

Less mass saves some strain on the binders, which don’t need too much help. Pads from CSG, stock rotors and calipers, a basic ducting kit, and even with Goodyear Supercar 3Rs and the aero loading, the brakes last an entire session without fade.

Mods were kept minimal. A set of SPL control arms for more camber and toe adjustment, a Sparco bucket seat, and a chopped exhaust rounded out the short list. Fortunately, the A90 just doesn’t need much help from the factory — just a sportier alignment:

With Jackie Ding’s advice, he increased front camber to -3 degrees, increased the rear to -2.8, set the front toe at 0, and, to minimize some of the bump steering, a smidge of rear toe-in. About 0.3 degrees, actually.

Tuning took some time to understand, but like his choice in modifications, he fumbled his way through it until he could learn enough to make the right decisions. “At first, I had the rear wing angle turned up to the max before adding the splitter, so at 8 at Thunderhill East, the car just went straight. That scared me. After that, I started to read up on aero balance.”

After adding a splitter and trimming out the rear wing, he found a sweet spot that gives him some reassuring push in faster corners. Combine that with a car that is easily rotated on throttle in the slower corners, and it’s not hard to see why he’s gone so much faster in the span of a year.

“As soon as I touch the throttle, I like it to rotate a little,” he explained.

And with that, he had a platform he could take to the track and run lap after lap. It’s super reliable. After forty-minute sessions at Thunderhill in 100F weather, the brakes and the engine remain cool. The Supra is happy to take the abuse.

His dedication to the craft, complemented by his studious approach and background in robotics helped him go from a total novice to someone fighting at the front of Speed SF Challenge’s S2 class in just two years. You don’t make that progress without cracking the books and being a little ingenious. Now pursuing his PHD in electrical engineering, he is confident he took the right path. “If you don’t have a budget to hire an engineer, you have to learn to do it yourself.”

Tailai has done most of the work in his garage. “From chassis tuning, I gained probably two seconds.”

And although he sees the importance in building a dependable, approachable, reliable car, he knows that racing is not just an engineering exercise. It takes practice, physical fitness, and coordination. So, after he adds the new Spage aero, the rest will come down to him. “There’s still a lot more potential there that I’m not getting. Honestly, I’m still a pretty bad driver,” he said.

For someone who’s currently lapping Sonoma in the 1:45s, but had no idea what an apex was a few years ago, that is a masterpiece of self-effacement. Not everyone advances this quickly in the sport, but Tailai’s taken the sensible approach and put track time first. If that isn’t a compelling case for reliability, I don’t know what is.

Justin's IS F: Rekindling An Old Romance

Photo: Nolan Muna

Justin had his first shot at track days back in 2003, but that one afternoon at Thunderhill East in his 7th generation Celica GTS would be the last time he’d set a tire on track for nearly twenty years. Still, he managed to set a 2:15 at that event, so at least he had demonstrated his chops in the process.

Then life intervened. Marriage, children, divorce, and other financial priorities forced him to put his racing aspirations on the back burner for the better part of two decades. During his seventeen-year sabbatical, he dabbled with motorcycles and a third-generation Mazda RX-7, but never took either to the track.

Once the kids grew up, Justin saw an opportunity to return to the track. Then the pandemic hit, and to make matters worse, he lost his job. For a bitter moment, his chance to return to tracking seemed to fall just out of reach. Rather than fall prey to despair, Justin began consulting, then went into business with a close friend. Fortunately, that career move proved lucrative.

So much so that he could suddenly consider several supercars. “I debated between an NSX and an R8,” he said, “until my fiance made a suggestion. She said, ‘Instead of dumping a lot of money into one of those, why not buy a cheaper car you can modify your own way?/”

Cogent question. Justin started considering the criteria he was looking for in a mid-tier car. Reliable, large displacement, naturally aspirated, and as he thought longer and longer, he grew to like the idea of a four-door. He cast his mind back to a stoplight-to-stoplight race during the time he was driving his RX-7. “I remember an IS F totally smoked me,” he recalled. Seemed like the big Lexus sedan fit the bill.

And so he started scouring the more reputable classifieds. There wasn’t much he’d find that seemed like a suitable candidate. Ironically, it was only after four fruitless months that he capitulated and started scrolling through the Craigslist pages, where he only spent a few minutes before finding the perfect car. Better yet, it was parked just a little down the street from Justin’s house.

With only 77,000 on the clock, one owner, and complete service records tucked neatly away in a binder, this immaculate machine held a lot of promise. However, Justin being a prudent guy, he had his friend at Magnussen’s Toyota inspect the car to be certain it was the gem it appeared to be. After performing the PPI, his friend told him, “If you don’t buy this car, I will.”

Justin didn’t give him the chance. With his new acquisition sitting pretty in his garage, Justin began researching what a track-ready IS F had over his bone stock example. At the very least, any set of performance shocks and brake pads would keep it from falling on its face. However, Justin being well connected in the industry, he splurged for the fancier stuff: Carbotech XP10 pads, Michelin PS4S, and HKS Hipermax coilovers.

His return to the track—Buttonwillow this time—after seventeen years away was comically carefree. “It’s just like riding a bike,'' he told himself. He set out brimming with pride and excitement, but he quickly realized just how tire technology had come in the last two decades—and how rusty he truly was. After dropping two wheels at the exit of Bus Stop, he reigned in some of his exuberance and started to drive much more sensibly. “It was eye opening and humbling, to say the least.”

A trip to Thunderhill West a few weeks later was not only humbling, but dispiriting. The IS F’s inability, so he thought, to handle the constant barrage of corners put him in a foul mood. In fact, he was considering abandoning the platform that day at a somber lunch.

Post-meal, he found a little more encouragement from the car and managed not only to stick in a respectable 1:33, but he executed a spectacular pass around the outside of Joe McGuigan, who was then riding shotgun in a student’s car.

Two months later, he had his 22/20k setup that convinced him to give the platform a fighting chance.

Joe, another proponent of the Lexus sport sedans, could see by the IS F’s bucking-bronco body language that the damping was insufficient for the workout Justin was putting it through. Following Joe’s recommendation, Justin reached out to Shaftworks and ordered a custom set of coilovers to suit the heavyweight.

“That’s when it spiraled,” he laughed. Along with those new coils, he picked up Ultra Racing chassis braces, FIGS arms and bushings, Sikky swaybars, and a few other items that stiffened the chassis to the point he could drive the car as aggressively and accurately as he hoped. Of course, the newfound cornering forces required some additional core support for the driver, so he threw in a Recaro Profi XL.

It didn’t take long before he had to fortify the platform again. With all the extra energy he was putting into his wheeling, the tires and brakes were struggling to keep up. “I tried RT660s, but they got greasy too fast. I spoke with a Camaro owner who recommended Goodyear Supercar 3s and figured I’d try ‘em.”

Now that the car’s sorted and sweet, he has to be careful not to overdrive the car. “It will do what you want, provided you keep it within a certain window,” he added.

Wrapped around a new set of Momo Catania wheels measuring 18x10”, he was thrilled with the newfound consistency these new tires provided him. “Once they’re warm, they remain at the same temperature for the rest of the day—it’s a little like cooking with a cast iron skillet.”

Naturally, the added grip strained the binders to the point of developing stress fractures and mirroring some. In their place, Justin added a set of GS F calipers, bigger OEM Brembo rotors, and a set of Carbotech XP12s to bring everything up to a dependable par.

Swept away by the rate of development and the improvements he was enjoying, Justin asked himself, ‘What could it hurt to have a little more power?’

With a custom tune from Tuned by LOI, full bolt-ons, and a tankful of E30, the 5.0-liter made a very healthy 438 horsepower and 401 lb-ft at the rear wheels. To make the most of this bump in grunt, he added a Sikky carbon driveshaft and an OS Giken 1.5-way LSD.

With the level of funding he’s put into this machine, Justin decided to make this former heavyweight into a svelte track-only sedan—and is leaving it to the pros to help realize its potential. Additional cooling, a welded cage, and some lightweight body panels are just a few of the additions Race Factory will be making this summer.

If all goes to plan, he’ll be trailering this beauty to several shakedowns next year before entering in Global Time Attack, where he hopes to make a splash in the Street Class. With the good luck he’s had thus far and the wise McGuigan to guide him on his way, he has a shot at making some waves with this (perhaps former) heavyweight.

“I just want to thank my family, friends, and the car community for being so supportive. Without all three, my return to motorsports wouldn't have been anywhere as fulfilling as it has been.”

Joey's Yaris: Giving the Family Car a New Lease on Life

Joey Rassool was bitten by the racing bug quickly after buying an FR-S a few years ago. Being a deep thinker and someone who never does anything by half-measures, he decided to take an abrupt left turn. Not everyone would see the sense in making the FR-S his daily and the automatic Toyota Yaris the track tool, but he had his reasons.

“I recognized the reality of modifying a car extensively—something I really wanted to do—and so I figured I’d keep the FR-S untouched. I had the family Yaris to play with, and since my siblings were done with it—it was a first car for most of us—I wanted to give it a new lease on life.”

It wasn’t convenience alone that drove Joey to choose the Yaris. After watching an SCCA H-Production race at 2014 Runoffs, he saw that this underrated econocar had real racing potential. So, without much hesitation, he and his brother Sam started modifying the Yaris for autocross. Tein coilovers, 15x8” Konig Hexagram wheels, 205-section Hankook RS4 tires, and a set of Hawk HPS pads were all it needed. A mild dent in the wallet later, they had a machine that would rotate better than most.

If there was one thing holding them back on the cone courses, it was the Yaris’ automatic transmission. Over the winter of 2019, he and Sam threw in a five-speed with an ACT clutch, and while the subframe was removed, they added stainless steel brake lines and new control arm bushings. Sadly, the fruits of their labor wouldn’t be enjoyed for another year.

Cheap seats, sticky tires, and a few bolt-ons were all this featherweight needed.

When COVID died down at the beginning of 2021 and they could finally get back on the track, they took it to the Streets of Willow, where the nose-heavy Yaris revealed a few of its flaws. “I really wasn’t familiar with how it would transfer its weight,” Joey began. It’s not hard to understand why the little Toyota was too happy to spin in the first chicane on the second lap.

“I really hadn’t changed much in the car then—it was all trial and error. I had a Whiteline rear swaybar in place that made the car just a little too twitchy. I started sorting the car out there. In fact, the whole setup problem—not a lot of people track these cars—has been like that. To get my first pointers, I had to consult some of the Honda guys to get an idea of what a car like this needs to go fast.”

“I realized it wasn’t the perfect platform in terms of weight distribution, but at least the problems happened at lower speeds,” he added.

A little twitchiness didn’t keep Joey from diving in headfirst. That year, he ran four of the five events of the TRD Series. The competition there encouraged him to find an ideal setup quickly, and with a set of stiffer BC Racing coilovers, he was able to counteract some of the nose dive and keep the short-wheelbased platform from rotating too much.

The Yaris may only make 100 horsepower, but it’s light. He went to great lengths putting this car on a diet; scrapping lots of the superfluous bracketry, interior, and even the heater core. Now, it weighs a little under one ton sans driver.

To capitalize on the cornering potential of such a light car, he consulted Chewerkz and added a set of shims to the rear as well as some eccentric bolts up front to achieve the camber figures he was after. Aftermarket being what it was, he had to rely on homebrewed ingenuity.

The resulting agility means minimal braking—in fact, this is a critical part of driving. “From the Bus Stop through to Phil Hill, I’m basically flat the whole time. This is a car which forces you to conserve momentum; braking as little as necessary, taking a shorter line when possible, and minimizing tire scrub.”

He’s still aiming to improve the balance. An LSD might solve some of the inside wheelhop and a Scion XB final drive should make the car peppier if not quicker. Its cornering forces cause fuel cutting in the quicker bends, so he plans on adding a baffle kit.

That list of mods might help his performance, which is already impressive for someone with only a dozen track days under their belt. This year, he finished fourth in the TRD Series. Plus, he’s aware that, at this stage, he could do more by working on his driving technique.

“Figuring all this out without much aftermarket support has been challenging, but the car is cheap enough to justify the trial and error. It’s been enlightening, too. Now, I think I understand concepts much better than I used to,” he added.

With this Yaris build, there’s the right mentality and the right sentimentality—he’s driven this car since high school—which makes me think they should go far.

Kevin Schweigert's GR86: Back to Basics

Kevin Schweigert’s fondness for the little Toyobaru products has waxed and waned over the last decade. His first, a first-generation BRZ, gave him that feeling of involvement that had him hooked. The lack of power led him to supercharging its engine and pushing power near the 400-mark, which proved to be a backloaded decision; axles and gearboxes needed replacing soon afterwards.

Tired of dealing with the temperamental blown BRZ, he traded it for a stouter A90 Supra that could happily handle 500 pound-feet. However, the Supra’s heft, increased running costs, and softer edges didn’t excite him quite like the little BRZ once did. In fact, he even considered hanging up his helmet.

Despite big power and impressive lap times, the softer Supra didn’t excite him like his BRZ did.

Thankfully, he didn’t have to do that. After getting a shot at testing his friend’s GR86 last winter, he sold his Supra and sprung for another normally-aspirated, lightweight, visceral, and raw machine. This time, another .4 liters will have to do; Kevin’s done with boosting an FA motor.

Without the former cars’ power, the new GR cannot hope to compete on longer tracks, but its combination of a larger motor and low weight is keeping Kevin quite busy. Significant torque increases and similar gains at the top end mean it’s happy to dance around in third gear in a way that the previous BRZ pre-blower never could.

Though power adders aren’t a priority right now, he’s planned out a few bolt-ons to get the FA24 making something closer to 250 horsepower at the rear wheels. A few duels with a lightly tuned AP2 S2000 has proven that it’s not lacking any straightline speed—and that’s with just a Counterspace Garage Spec Touring exhaust bolted on. This was done mainly for the fact that he couldn’t live with the digitized noise piped into the cabin. “It just wasn’t right,” he said.

He’s made good use of his connections at Counterspace Garage to get his latest acquisition into fighting shape—not that it needed much help. His list of modifications is fairly short, but the effect is obvious. “I wanted more stability and sharpness via the coilovers,” he stated. Thankfully, the ones used didn’t cost him much—they were once the coilovers he ran on his GR. “I had them revalved for 2kg less spring rate since this car is driven to the track,” he added. These CSG Spec Tein SRC V3 (7kg F 8kg R) aren’t the only hand-me-downs—he’s also got an OEM 2013 rear sway bar. Two hand-me-downs and he had all the pointiness he was after.

Stopping also needed some work. For Kevin, the CSG Spec C1/C11 pads don’t fade, last forever, and offer great modulation. Of course, a wider set of shoes helps there, too. His car wears a set of tasteful 17x9.5” Volk TE37 TA +44, including a 10mm front spacer, shod in 255/40/17 Maxxis RC-1 R2.

At this early stage in its development, he’s been able to go sub-two at Buttonwillow CW13 without wings or slicks, and from the onboard footage, it’s not hard to see why. Assuming the angles are kept reasonably shallow, the car can be shimmied in on the brakes and wiggled through the middle of the corner—several times if necessary—to get through the corner quickly and stylishly. The straightline speed isn’t anywhere near as great as his Supra’s, which also likes to dance around in this fashion, but the GR’s low weight, moderate power, and greater communication makes it a more involving drive.

“It’s pretty much telepathic,” Kevin adds.

It’s got the right sort of rack as well as all the sensory inputs needed to keep an aggressive driver completely engaged and satisfied—straightline speeds be damned. An audible beep every time he nears redline, plus a rife bolt-like throw of the gear lever help the 2.4-liter motor stay in its ideal range. Again, this engine’s not a top-end screamer, but the added displacement means the ratios don’t need to be shuffled through so frequently, and that rear end will move around just a little more with some third-gear stabs of the throttle.

That willingness to rotate, plus some mild engine tuning and a few aerodynamic additions might make this GR a contender for the S4 title. Will Kevin take the crown? It’s hard to say, but it’s definitely in the realm of possibility. What’s certain is that he’s rediscovered his love for tracking—and that’s what matters.

Showdown at Sonoma: Battle Between the Fastest Stateside A90 Supras

They’d known each other from the forums and hours on the phone, but they hadn’t met in person. For the last few years, both Jackie Ding and Will Kwok have developing some of the fastest A90 Supras in the country, and only recently were about to partake in some friendly competition.

Jackie’s PhD Racing Supra, now famous online thanks to his growing YouTube channel, caught the attention of Will in 2019. “Will quickly became a huge supporter of PhD Racing Lab and is now our biggest customer. He’s always a great guy to talk to, so he was one of the first people I told I was coming out to the West Coast. Naturally, we started talking about a little battle when I was there,” Jackie told us.

It was Gary Wong, Will’s hired hotshoe, who supplied Jackie with Speed SF’s schedule. Jackie picked the dates that interested him, and the two decided to have themselves a duel. If Jackie couldn’t finish more than a half second ahead of Gary at Gary’s home track, he’d have to buy dinner.

Footwork

Since Will got most of his pointers from Jackie, perhaps first real time attack driver to develop the A90 Supra in the U.S., the parts used on the two cars aren’t that different. Both share most of the SPL catalog available for the A90, including the SPL front lower control arms, SPL adjustable front caster rods, SPL rear toe links and eccentric lockouts, SPL bumpsteer correction kit, SPL rear traction links, SPL rear upper lateral links, and SPL front swaybar endlinks. There are a few notable differences, though; Jackie’s car sports the Reinharte two-ways coilovers while Will’s is on MCS three-ways.

Powerplants

Supras have a certain reputation to live up to, and both these cars do that with over 1,200 combined horsepower. Jackie’s B58 is improved with VP MS109 direct injection and a Garrett GTX3076R Gen 2 as part of the AMS Alpha 6 turbo kit. The total output: somewhere in the 650-horsepower range.

Will has explored a little more of his motor’s potential. His sports the Pure800 turbo, flex fuel, and port injection,—enough for 700 horsepower at the real wheels, depending on power map. The power outputs are similar, but Jackie has to leave a little on the table as his gearbox hasn’t been built, unlike Will’s.

Though slightly heavier, Will’s car is a little faster on the straights due to a stronger gearbox and another fifty horsepower.

For both Sonoma and Laguna, both cars sported the same tires: 275/40/18 CSR. However, the grip levels provided varied due to weight and aerodynamics. Jackie’s car-driver combination is somewhere around 150-200 pounds lighter than Gary and the purple car, and the configuration of wings and splitters are different enough to provide very different characters. While Will’s car has the Spage V1 front splitter, Jackie’s has the V2. Both running the Spage SP012 68” swan neck GT wing, but Jackie’s wing is mounted slightly lower for a less understeery setup.

Similar setups, similar parts—that would be the case since Will has relied on Jackie for tuning advice. However, their design ethos differ somewhat. Jackie’s car is much more suited to the high-speed stuff, while the purple car is more compliant, more squishy, and better suited to the slower tracks on the West Coast.

Subtle Differences OVER one Lap

For the first half of Sonoma, Gary held the edge. The bumps in Turn 1 were tough, but when it came to hard braking and high-speed direction changes, as in Turns 7 and the 8/8A esses, Jackie and his slightly pointer car pushed ahead. Turn 10 obviously favored the aero grip of the red car, but it wouldn’t be fair to say it was as simple as turning the wheel and matting it. As we can see in the footage below at 8:53, a little braking too late and adding a little too much throttle after the speed change prior to Turn 10 caused a moment which might’ve given Jackie a little heart palpitation. Without a doubt, Sonoma is a driver’s track that Jackie had to learn in a hurry.

“Their car handled the bumps better, so in sector 1 at Sonoma, Gary definitely had an edge on us. Our car, being more stiffly sprung and heavy on compression, is a really high-speed focused aero car. While we lost a little in Sector 1, we gained that back in Sector 3’s high-speed esses,” Jackie elaborated.

“I was surprised with the braking performances. We were both running the same CSG pads, but I think I had more confidence in my brakes, even though I’ve only got a Stoptech Trophys on the front axle. Will’s car has APs 9660s front and rear. I think the big reason for that was our more advanced front splitter; having that extra downforce gives us extra front grip under braking,” he added.

At the end of the day, the main difference was in downforce. Both cars produce comparable grunt and share the same footprint, but subtle changes in aero balance and perhaps a slightly svelter shape gave Jackie a slight edge around Sonoma, though it’s only fair to mention he’s been developing this car longer and driving it a lot more. Still, nobody felt shortchanged at the end of that glorious day. Sonoma’s not the easiest of tracks, and it definitely doesn’t suffer fools, and to put that much power to the road through moderately sized tires and not crash is an accomplishment in itself. Dinner looks cheap after the cost of a smashed carbon clamshell.

A No-Compromise Toyota MR2 Named Frog

Joe McGuigan made a bit of reputation for himself with a nicely sorted FR-S. Light, agile, very pointy, and usually driven with a lot of slip angle, Joe’s FR-S was an attention getter. It was genuinely fast, too. He spent a few years developing the car and hit that hard-to-find medium of both playful and quick. Like few other cars in its class, it would genuinely fire off corners while sliding in a way that few vehicles really can.

But the limitations of an FR car are noticeable when you’re trying to find every mid-corner mph available. Basically, its engine placement and suspension design might not strike some as perks. True, an FR car—and particularly the FR-S—is usually an easier car to drive and his is fairly forgiving for how much it slides, but Joe sought more in cornering performance. No compromises, no luggage compartments, and no forgiving weight transfer mistakes.

The nickname “Frog” definitely fits this squat scalpel.

The replacement was about as harsh and confining any streetable car gets. This third-generation Toyota MR-2, better known to fans of Best Motoring as an MR-S, is a truly tiny car.  Surprisingly, the interior is relatively spacious, hence why a 6’3” guy like Joe has not one, but three in his garage currently.

But once he started tracking it, he gelled so well with the little roadster that he forgot about his bruised knees and elbows. Although the MR2’s wheelbase was lengthened to improve stability, it’s still about five inches shorter than the FR-S’. Its overhangs are unusually short, and with an engine placed in the ideal position (mounted laterally, no less), the weight is in the right place everywhere. Speaking of, there isn’t much weight to consider; the MR-S, when fitted with a hardtop, weighs only 2,200 pounds.

“I’ve got a habit,” Joe laughs. “It’s the fifth MR2 I’ve owned, and by far the best. Once I picked this one up, the floodgate opened with all my friends offering parts for cheap. I guess that’s called a good problem to have.”

With the right setup, Joe would be able to get the car to do things that the FR-S simply couldn’t. Swifter steering and shorter braking distances were the obvious benefits, but as he learned, he had easier access to more mid-corner rotation and better traction at corner exit. He could exact his will over this car in subtler ways; its response to weight transfer made it a little spikier and certainly more sensitive to his inputs, but when driven properly, much more adjustable.

That development period was further shortened by having a friend, Tony Rodriguez, who gave Joe a proven modification route to follow with his own track-spec MR2. In addition to following all the suspension leads that his friend gave him, but he learned that the ZZ motors need a little cooling assistance for track work. In fact, the original 1ZZ in the MR-S couldn’t handle the summer temperatures and popped after just eight track days. Though Joe considered throwing in the towel, he grabbed a better motor—one with an oil cooler to keep things in order on August afternoons.

The Link ECU from Panic Wire was used on the 1ZZ. To make life easier for Joe, they have included a subharness for the VVTL-i sensor and oil pressure sensor to make installing the 2ZZ a plug-and-play affair. They actually transfered over the 1zz OEM engine harness as everything plugs in the same

The 2ZZ motor, improved by a Link ECU, a set of cams, and a little optimization from Unrivaled Tuning, is a real lively, top-endy sort of engine that will trump a lot of mid-range turbo motors in terms of sheer exhilaration. Plus, it’s not gutless; the little 1.8-liter makes a healthy 190 horsepower at the wheels. Coupled to a Lotus six-speed with revised ratios, this featherweight MR2 is not a momentum car in the truest sense of the term.

The current modifications are:

The only setup changes made post-swap are a little more rear wing angle, fender flares, and a slight stagger instead of the original 225/40/15 square setup he originally ran. It neutralizes the car, which now enjoys an additional 60 horsepower over the original iteration.

It still verges on oversteer at most times. For that reason, the tired phrase “handles like a go-kart” might actually be appropriate in this instance. This MR2 is pointy, eager to change direction, snappy when trailbraked incorrectly, and on a fast lap, usually dancing under his control. In many ways, it really is like a quick kart.

It should only get easier to drive and less frenetic when the setup is improved, but for now, it’s plenty thrilling, even with a few rough edges.
