Alex's AP1 S2000: Earning His Spurs

Tempted to try something livelier than his DC1, Alex bought himself an AP1 S2000 a few years back and learned how lively it really was. He chose his modifications with the aim of making it reliable and predictable, and in doing so, built a foundation upon which he could learn his craft.

Though this AP1 wasn’t Alex Caruso’s first track car, it was the car with which he truly earned his spurs. A few years before buying this car, he got his feet wet with an NA Miata, then later an Integra GSR. Thesef two taught him about car control and patience with the right foot, but they lost their appeal with time. Eventually, he wanted to try something a bit more exhilarating. By then, Alex was no longer a student just scraping by, and he had a little more to spend on a special sort of car.

When this car popped up in his feed, he immediately checked his bank balance. Hardtop, great paint, totally stock, and basically a blank slate with which he could express his creative streak. There was one problem, though: he couldn’t quite afford it. Undeterred, Alex committed to finding the money. With the help of his supportive wife, he scraped together enough for a down payment and brought it home.

Not long after, he started leafing through those old lists of dream parts he’d scrawled away when he was a daydreaming, broke college kid. The first round of mods were intended to make the motor indestructible. Because the ‘01 models didn’t receive the piston-cooling oil squirters the following year’s motor did, he retrofitted those to fit his motor, careful not to crossthread anything down there. Following that, he added AP2 valve retainers, then sent his valve covers out to be drilled; the AP1’s valve covers need to be perforated to help move some of the blowby.

Though these drilled valve covers works with the stock PCV system, Alex added a catch can—one which doesn’t need emptying until the fifth track day.

With the powertrain bulletproofed, he started running his car to the 9,000-rpm redline and enjoying the honeymoon phase, spins and all. The AP1’s nervousness was thrilling, challenging, and hugely educational—even if he had to clean plenty of grass out of his wheel wells. “Once I started pushing, I looped that thing so many times,” he laughed.

Though AP1’s dynamic toe curve kept him busy and certainly accelerated his steering corrections, he felt it prevented him from totally trusting the rear. “It almost felt like the rear was taking two sets in every corner,” he explained. In an attempt to get closer to his car and predict its movements better, he started with the second round of improvements.

Wisely, Alex went for a full set of Blacktrax sphericals, Hard Race motor mounts, and solid LSD collars. The added responsiveness and transparency of the car grew in proportion to his confidence. However, there was one glaring shortcoming he still hadn’t addressed.

That pesky toe curve could only be truly changed by swapping out the old AP1 subframe for an AP2 subframe. The first weekend out, the car was predictable and encouraging in a way Alex had never felt before, and so the second honeymoon phase began.

Never once in his four-year relationship with the car has he felt bored with the car, but he has always wondered if the wear items would let him down. To give him peace of mind, he reinforced the flimsy spot where the front upper control arm connects with the chassis. While at it, he swapped all four hubs out for Karcepts items and rid himself of another potential nightmare.

Finally, after a year of tracking his stout and predictable AP1, he started searching for more speed. The first round of go-fast goodies consisted of Sake Bomb Garage’s brake kit, a set of JRZ RS Pros, and a few engine bolt-ons—the last chosen mainly for noise.

“The coilovers really transformed the way the car handles over rough or uneven pavement. I knew the stock suspension was already well-tuned by Honda, so I didn't want to skimp on coilovers that would ruin the handling characteristics the Honda engineers worked so hard to develop. After popping my right rear upper ball joint out of its control arm coming at Laguna Seca, I knew wanted to get something that could control the chassis better without bottoming out as frequently or harshly.

I happened to make a connection with a JRZ vendor and scored a deal on a set of RS Pros. Now, not only is weight transfer much more immediate, I don't have a second thought about the car unsettling over bumps, like the Dorito at Thunderhill West. Having two-way adjustable coilovers also opens up a whole new world of suspension tuning that I'm slowly learning about. The ability to adjust the handling balance at the track and the peace of mind that the dampers will soak up any bumps I throw at them make these coilovers worth their weight in gold.”

The focus on the foundation, the time spent learning an imperfect car, and the carefully chosen selection of performance modifications all paid off in the first session following. Running on the same set of Hankook RS4s he’d used the time before, he dropped his times at Thunderhill West by two seconds.

There’s not much more this dependable car needs. It’s lively, reassuring, and while it’s not the punchiest car in the field, it is one of the most agile. Because he prioritized predictability and transparency over any other performance trait, he might opt for an aftermarket differential—Seigo Ma’s shown him how important they are. Maybe a little aero in there for good measure, but beyond that, all he needs is good weather and the time to spend with his second love.

“With how much I’d dreamed about this car before buying it, I was worried that I would be disappointed with the S2000, but I can safely say it's lived up to all of my expectations and then some. It's been rewarding to work on, to fix, to push myself with, and it's the exact tool I needed to get comfortable on track.”
