Michael’s 350Z: Take A Chance, Prove a Point

Twelve years with an unloved chassis has given Michael “Stubz” Hillo a unique perspective on taking the underdog route. There are other established, well-paved paths with minimal maintenance and certain outcomes, but they don’t offer a maverick a chance to prove a point.

Stubz took it upon himself to take the unloved 350Z and make it into a NASA ST4 race-winner because, well, he hated the idea of conforming. However, before he started his mission, he was after an affordable way to begin drifting. Nowadays, the 350Z is one of the few Japanese sports coupes that offers the sort of value the budget drifters offered back in drifting’s heyday. Even then, it was pretty cheap.

It was more than just an option for the cost-conscious drifter, as Stubz realized. Beyond low overhead, a torquey motor, and a rear-drive layout, the Z has a lot going for it. It’s reasonably stiff, the aerodynamics aren’t terrible, and the aftermarket is decently sized. It might not be as well supported as the E46 M3, but it offers similar power-to-weight figures and the potential to run respectable lap times at a fraction of the price.

The zeal and the commitment to proving the platform came later — at first, it was cheap fun. Beating up on pricier cars was only part of the pleasure; the steering was full of feel and responsive, the motor responded well to modifications, and the rear end put the power down decently.

Some of that luster began to fade when he tried to turn the Z into something more than a midfield car. The budget modifications no longer seemed to be enough, and so he tried experimenting with the high-end brands which only offered limited support for the Z.

After testing Penske and Godspeed coilovers, he settled on MCS two-ways with 18K springs up front and 9K in the rear. The car still lacks some of the compliance he’d like in slower corners, but it works well enough in the fast sections, thanks in part to Epsilon+ aero, that the compromise is acceptable.

The most irritation has stemmed from the car’s flawed braking system. Persistent knockback issues and lousy OEM ABS pushed Stubz into spending hundreds of hours diagnosing and attempting to find a package that would work.

Plenty of thrown wrenches and a thousand curse words later, he found a set of Stoptech Trophy big brakes that did a reasonable job. Because they moved the brake calipers closer to three o’clock, they mitigated some of the knockback resulting from the steering knuckle flexing. The remaining bugbear was the ABS system, which needed to be retrofitted with the Bosch Mk60 kit from Race Harness Technologies.

Though the braking system works decently these days, Stubz isn’t completely satisfied. Trailbraking has improved, but the outright braking performance hasn’t gotten much better. However, some of that has to do with the weight of the vehicle, which has been hard to lose with conventional stripping methods. “You’ve gotta get pretty creative when it comes to putting the car on a diet. I didn’t want to, but I had to buy carbon. Hatch, hood, front bumper, and headlight blanks from Spinnaker Composites have helped, but the car is still heavy.” he explains.

It’s transformed into a reasonably swift car in recent years, even with the diminishing returns from spending big bucks on primo parts. The 3,200-pound Z has an average of 257 horsepower which is pretty well administered thanks to 275-section Toyo RRs and the aforementioned aero. A broad powerband helps make the car less track-sensitive than some, and, anyways, Stubz no longer agonizes over finding the perfect setup. After several years of head scratching, he sees the Z as a dependable, safe, and sturdy car which is easy to run and satisfying to drive. Going for the gold isn’t his aim any longer — he’s happy with what the 350Z’s speed. Any car that can lap Buttonwillow W13CW in 1:54 is more than just fun — it’s seriously fast.

Striving to perfect the car sapped some of his ambition, but it’s also given him a few notable wins, wisdom, and a pragmatic approach that provides him with peace of mind. His lack of zeal might not motivate newcomers to try and beat the odds, but if they read between the lines, they should realize that there’s nothing with the Z as an entry/mid-level car. It might not carry an ambitious driver to the top of the podium, but its golden era-pricing lowers the barrier to entry. It’ll help them get involved faster — and in Stubz’s view, that’s better than sitting on the sidelines and dreaming of victory.

Ken's 240SX: Twenty Years in the Making

A student of motorcycles, Ken Yu spent his formative years tracking two-wheeled vehicles at Thunderhill, Laguna, and Sonoma. Eventually, he grew tired of taking spills and started looking for a four-wheeled way to get his fix. Specifically, he wanted something easily modified and cost-effective. Back in 2001, 240SXs could be found for nearly nothing — especially ones with blown motors.

A Zilvia.net posting led him to this 1989 hatch, which had been sitting for some time and needed a little love. Well, a lot of love. Aside from the blown motor, there were some serious issues contributing to the low cost of the car. “Someone left a burger in the back. There were maggots everywhere!” Still, $1,500 was a steal.

He started with a basic set of suspension upgrades. Whiteline sway bars, Megan Racing track coilovers, SPL lower arms and tension rods.

Out came the interior and in went the vinegar solutions. Then came a stock SR20, Z32 brakes, Tokico shocks, 5Zigen wheels, and Federal tires for plenty of fun in those halcyon post-college years. And this first round of modifications didn’t break the bank; many youngsters could swing these back then — no pun intended. When a full S13 front clip only cost $2,500, it was not too hard to put a quick 240SX together.

Rather than take the typical drifting route, he decided to make his 240SX corner. At 2,600 pounds with ~200 to the tires, the 240SX could graze 100 at the end of Thunderhill East’s front straight. It was nimble enough to get around many autocross courses, too.

By transplanting the motor without replacing the coolant hoses, Ken blew a pinhole leak in a coolant line at Thunderhill in the middle of July. Three of the ringlands broke, sending shrapnel into the head. He managed to limp the car all the way home to Hayward with regular coolant top-ups, but the SR was toast. He rolled it into the back of his garage with hopes to quickly replace the motor, but he didn’t bet on the next chapter of life taking him down a very different path than he’d pictured.

Ken got married, had two kids, a dog, and bought a house, so the track toy no longer took precedence. However, he kept the dream alive over the next five years by amassing a small stockpile of go-fast parts and tools.

Starting seven years ago, from ten to midnight — after the kids had gone to sleep, Ken would sift through his parts pile and make small steps towards rebuilding the car. Megan Racing coilovers with Swift springs, a pair of Sparco seats, an extensive cooling package, and a bolt-in cage set the tone: it was going to become a full-on track car built on years of forum trawling.

With his new CD009 on the floor, Ken spent a couple nights fitting Jun Flares and GarageMak overfenders.

Lots of research was needed to find out all the desired suspension settings for the 240SX — no darling of the track day community. With relatively scant information available for track-oriented S-chassis, he had to consult some of the video library he’d amassed over the years. “I’ve been watching Video Option since Volume 12.”

As this would be a fat-tired track car with a need to put power down better than what a stock S13 ever could, he had to identify the flaws of the suspension setup.

Up front, he added a set of Geomaster knuckles to lower the roll center for improved camber and toe curves. Along with that, he threw on most of the S13 parts in the SPL catalog, Techno Toy Tuning’s lower front arms, and even an S14 rear subframe for slightly better geometry and a wider track. Thankfully, retrofitting the older car with this S14 part only required a set of conversion bushings.

It would have to stop well, too. There were the two-piston rear Brembos sourced from a 2004 Subaru STI and mated to two-piece Girodisc rotors with Carbotech XP12s. Installing them was a cinch, too — almost a bolt-on affair.

At the front, the Core4 Motorsports Wilwood six-piston with Carbotech XP16s fulfilled the same need for easy modification, while offering far more reassurance than any hodgepodge of other car’s parts. Any track rat loves knowing that the kit on their car has been used by Core4 on their Silvia build for AER endurance races.

“Collecting all those parts was what kept the dream alive.”

When the ball was officially running, he called on two respected old school shops to help him rebuild the one piece he didn’t replace himself. Lonnie Jenson Co increased the SR’s bore to 86.5 mm and assembled the bottom end with Eagle rods and CP pistons. Performance Options rebuilt the head, while Ken added HKS Step 3 camshafts and dual shim rocker guides to keep the head from vibrating itself to bits at higher revs.

With a whole new fuel system and a Link G4X standalone ECU to decide on the right blend, Ken knew that he’d be stretching the stock gearbox to its limit. A Mazworx conversion kit, a CD009, and an ORC twin-clutch disk made up the the beefy new drivetrain — more than strong enough to handle 360 horsepower at 310 lb-ft at 5,500 rpm. That was sent back to an S15 helical differential with a 4.3 final drive. The combination of this gearbox and rear end resulted in explosive acceleration.

Getting tuned at Blacktrax.

After bolting in and tuning the new powertrain, the car would hook when pointed directly ahead, but the lack of compliance over surface variations caused Ken a few spins. At first, Ken struggled to find much grip coming through Turn 3 and 3A at Sonoma. “The inside wheels kept losing contact due to the lack of droop and suspension compliance. The solution was to ensure 30% of the suspension travel was reserved for droop through the helper springs,” Ken noted.

With more toe-in at the rear and a TCS Sportline rear wing, the car’s stability improved at higher speeds and under heavy braking. Being heavier in the front than the rear, it still gets a little light over the crest of Laguna’s Turn 1, but it’s less than vicious. The wingless iteration felt like it might bite his head off.

To expect much more from the projet would be unfair. December 30th was the first time he had this car on track in over a decade. And, wisely, Ken wanted to study the ways to get a dependable car out on track first.

Clearly, Ken’s done his homework. The engine manages temperatures well for a turbo car — admittedly, only cold-weather testing has been done so far, but it’s likely cooling won’t be a problem except perhaps on the warmest days.

The geometry is improved, the drivetrain handles the horsepower well, and the maintenance it requires is relatively low for an old Nissan. There’s also little tweaks that show an attention to detail and an emphasis on presentation, like how the ISR exhaust extends far enough to avoid blackening the bumper. It’s pretty — and that’s not always a great descriptor for a 240SX with bolt-on over fenders.

The attention to detail and insistence on putting reliability first will make the car’s issues easier to diagnose. However, half the car’s ancillaries are OEM SR20, so time will tell how well they’ve weathered the elements.

It’s clear Ken’s laid the right sort of foundation. Coilover testing, adding a front splitter, and increasing body rigidity are the main items on the agenda. Seam welding around the hatch and the doors — two massive apertures for such a small body — should make another massive step forward in making this middleweight handle well. Buttoning it up will take time, but Ken’s already sunk two decades into this car and his enthusiasm for tuning the 240SX hasn’t diminished one iota since the start. In the grand scheme of things, what’s another year?

Laguna Seca Logistics: Where to Stay, Where to Eat, What to Wear

California’s internationally famous track is Laguna Seca, and it’s known so well for good reason. Nestled in the rolling Monterey hills, this 2.2-mile track incorporates a memorable combination of fast, flowing sections and tricky, technical parts combined with spectacular scenery and temperate weather. The camber changes, blind entries, and heavy braking zones make Laguna Seca hard to master, but that doesn’t matter—any visit to the track, even if the corners are confusing you, is enjoyable.

It can be slippery in the morning.

Its serious elevation changes make for a challenging drive, but also offer some scenic vistas that the observer should take advantage of; few tracks in California can be seen in near-entirety from one vantage point. However, if you want to reach the Corkscrew and peer down on this spectacular circuit, you’ll want to drive—unless you’re in the mood to burn some calories.

Being stuck in the middle of some rolling hills and so near to the ocean, the basin which the track is built in can collect fog in the morning that takes some time to burn off. Even if the weather report says it'll be warm, the fog lingers early, so bring a jacket. If you’re in one of the first run groups to run on a foggier morning, it’s best to treat it as a warm up/wet session and give the tires plenty of time to heat up before pushing.

Also, the proximity to the ocean and warm inland temperatures also attract some wind, so if you’re looking to keep your belongings from blowing away, renting a garage space is worthwhile.

Being a track with some cachet, it features plenty of amenities for those looking to get away for a special weekend. It’s also accessible enough to warrant a day trip. Nearby downtown Monterey has no shortage of restaurants and hotels, though they’re not too cheap.

That status comes at a price. With the high cost of high-DB days at Laguna Seca, some are looking to cut costs in the ways the can. The track does provide gas (91, 100, and 110-octane), but it’s significantly cheaper to get gas in town. One conveniently located station is the 7-11 on Canyon Del Rey Road. In addition to cheap gas, it has a digital tire inflating machine and a Starbucks on-site.

However, if you’re driving one of the bigger rigs, you will need to plan your fuel stop early. A two-car trailer will only fit in the truck stops in nearby Salinas.

One way people try to keep their weekend from breaking the bank is camping. There are 380 spots to park a trailer, and the costs are very reasonable. Showers are available by the T5 sound booth, and the numerous vantage points make the event casual and comfortable for friends and family. Staff can also accommodate leaving a car overnight for a small fee; the on-site security staff are great.

However, the sites can’t accommodate trailers of all sizes. Anything larger than a single car trailer is pushing it, and even a thirty-footer is going to be snug it. Also, make sure to prep for wet weather as the fog and mist collects between the hills and takes time to disperse.

For camping information, call (831) 242-8200.

Being a well-traveled area, there are plenty of nicely appointed hotels and restaurants—especially in the safer Seaside area. We tend to avoid some of the cheaper hotels in nearby Salinas.

The hotels we’d recommend are:

Holiday Inn Express Monterey Bay

1400 Del Monte Blvd, Seaside, CA 93955

Discovery Inn

1106 Fremont Blvd, Seaside, CA 93955

The track’s on-site cafe makes good barbeque, teriyaki, burgers, and so on. If someone wants a little more than track food, there’s plenty of restaurants, ranging from Two nearby restaurants within twenty minutes of the track are:

Tarpy’s. Located near the track and able to accommodate larger parties.

2999 Monterey Salinas Hwy, Monterey, CA 93940

Turn 12. Situated a little nearer to the center of town, this motorsports-themed restaurant is casual, but classier than most racing-inspired restaurants.

400 Tyler St, Monterey, CA 93940

Monterey Cookhouse. Not often discussed, but tasty and affordable.

2149 N Fremont St, Monterey, CA 93940

Since a weekend at Laguna can be costly, some opt to buy their food at the grocery store. Thankfully, there are plenty nearby.

Safeway

815 Canyon Del Rey Blvd, Del Rey Oaks, CA 93940

Nob Hill Foods

1320 S Main St, Salinas, CA 93901

Unlike so many of the tracks in California, the surrounding environment makes it easy to relax and make a real weekend out of a trackday; friends and family not doing any driving can still find numerous ways to entertain themselves outside of the circuit.

Final Few

• Bring a helmet—there are no rentals available.

• Make sure your car isn’t too loud—there is a 95 db sound limit on most track days.

• Because traffic at the end of the weekend is almost inevitable, make sure to stock up on snacks before heading home on Sunday. It’s unfortunate, but a couple hours in traffic is a small price to pay for a fun weekend at this fantastic track.
