Behold: NSX number 58 from production year 2004. It's been repeatedly shipped from one side of the country to the other, had a gamut of NSX-R upgrades from Nippon installed, was gently stroked to climax, and then outfitted with one sinister supercharger to bring the boost. But that's progress for you. From a simple start with Civics to an all-out RSX, this car's owner has finally found his place. But I am going too far back in history now; what you as the reader need to know is that this whole build began with an overpriced Nissan.
At the tender age of 25, Sky Nguyen was ready for a new project car. He was in search of a "career car," one that would always look timeless no matter what the chassis' age might be. The R35 Skyline had just made its debut in the U.S., and its combination of extreme power and all-wheel-drive handling made it an obvious choice. After a spirited test drive, Sky was ready to sign, but then the price tag became apparent. This was way more than Sky was willing to pay, so he opted to look for a substitute until the R35's value went down. Dealer after dealer was visited, and every time Sky left thoroughly disappointed by what he had found (or didn't find) in the R35's competition. But Sky still had to visit the Acura dealership.
Sitting spotless on the showroom floor was a red 2004 NSX, and it was lust at first sight. A brief test drive proved the NSX's handling met Sky's expectations, but when his foot hit the throttle there was a lot of muscle missing from the equation. While this certainly was a conundrum, desire eventually won him over, and he opted to purchase the car. But that R35 still beckoned in the back of his mind, so he left the dealership with the full intention of selling his NSX in a few years to acquire that other supercar.
The moment Sky brought the NSX home, he hopped online to study up on his new toy. He became a member of nsxprime.com where he learned as much as he could about the chassis. After few months of driving the car, he came to an interesting realization: His NSX gave him a level of connectivity to the asphalt that he had never experienced before. It made him feel like the car and he were one, and he could always predict its characteristics no matter what was going on outside. It is at this particular point in the story that Sky decided to tell the R35 "good riddance."
He opted to build his NSX to contend with the Skyline. He wanted to turn the two-seater into a true supercar, not just something that looked like one. So he picked up a supercharger from Science of Speed after discovering that it offered better power gains over the Comptech unit Acura was offering at the time. Word on the web had pointed him to Source 1 Automotive in Cincinnati, Ohio; so he shipped his NSX off to the shop's owner, Brian Urlage, for the install. They installed the supercharger, gave it a tune, and suddenly this beautiful NSX was making 385 hp at the rear wheels.
But after some driving time, Sky realized that 385 whp could never outpower an R35. The NSX was capable of a lot more, and he knew it needed a bigger, fully built motor. Driving Ambition outside of Sacramento, California, had come highly recommended on nsxprime.com, and after a few conversations with the shop's owner, Shad Huntley, he opted to ship off his NSX...again.
Building a motor for something as expensive as an NSX means you don't want to make any mistakes, so Shad convinced Sky to go with a 3.5L Comptech stroker kit, which proved to be far safer once paired with higher boost. Shad also fully built the top and bottom end of the engine and modded the supercharger to run 15 psi safely. After four long months in the shop, the engine was finally finished and was safely pushing 555 whp.
With the NSX's power issues successfully addressed, Sky now wanted to update the look of his NSX. So he shipped the car back to Source 1 Automotive for the finishing touch, starting with a set of custom Volk CE28s and a Stoptech big brake kit. Since the car is primarily street driven, KW V3 coilovers were installed, along with a beefier NSX Type R front sway bar. To finish off the footwork, an Umbrella VRH airbag setup was installed in the front to assist Sky over those pesky speed bumps and to save his undercarriage from untimely mishaps.
Sky wanted to keep the smooth OEM contours of the car, so a Super singular Route KS ZAZ front lip and side skirts were sourced from Japan, while the rest of the NSX was made to look as close to the NSX-R as possible. Downforce was a natural choice, and many of the company's carbon NSX-R offerings were installed, including a hood, hood duct, spoiler, rear valance, engine hatch duct garnish, and license plate garnish. JDM NSX-R exterior badges, doorsill badges, and custom LED fog- and taillights were installed. Interior upgrades consisted of an authentic NSX-R steering wheel, shift knob, seats, shift boot, gauge cluster, and a super-exotic JDM NSX navigation pod.
After all is said and done, this NSX is just astounding. It has power mods, exterior and interior additions, and has undergone several bouts of surgery. It performs like no other, forever looks the better, and has single-handedly destroyed one man's dreams of owning an R35. There were no corners cut during its transmutation, and it is now exactly what its owner wanted to begin with: a supercar.

Inspiration for the build
Don't know yet
Based just outside of Sacramento, California, Driving Ambition is a shop that specializes in building Acura NSXs and S2000s to whatever level is desired by the vehicle's owner. What started off in the 1980s as a small shop in Portland, Oregon, that catered to all kinds of exotic cars, has slowly transformed into a haven for NSX heads. And all of this came to pass thanks to the son of the shop owner, Shad Huntley. In his younger days, Shad won four IKF Karting championships, and became a registered "Expert" along with fellow drivers Scott Pruett, Mark Dismore, Jamie McMurray, and the late Greg Moore. From there Shad went on to graduate with honors from Wyoming Technical Institute, and hopped right into a career as a mechanic for Comptech Machine upon graduating. While there Shad was a key force in building (and maintaining) the championship-winning IMSA Camel Lights Acura, but after three seasons of domination Shad grew bored with the car, so he began open-wheel racing in the CART series where he became the youngest Chief Mechanic ever. In 1997, Shad was named Chief Mechanic of the Year while heading the Carl Hogan team with rookie driver Dario Franchitti, and later that year, Shad decided to lend his technical expertise to Comptech as director of product development for its race-inspired performance parts for Acura and Honda. In 2006, Shad opted to reopen Driving Ambition's doors to the public. So Shad has come full circle, in that he has successfully returned to the fold as the head honcho at Driving Ambition, where he plans to continue building cars like Sky Nguyen's NSX.
