Dallas Star - Jeff Nguyen's 2002 BMW M3

Mild Car To Wild Star; Jeff Nguyen Finally Completes His Supercharged BMW M3 Project.

Almost two years ago, Jeff Nguyen told us he'd built his car to be mild. "Mild meant trying to heavily modify the car yet not have it appear over the top with crazy bodywork or bright paint," he said at the time.

Fast-forward to today and Jeff's not the same person. Formerly residing in Los Angeles, he's back in his hometown of Dallas, having graduated from dental school and happily married to his wife, Caroline. But during all this activity, he found time to re-think his approach to his '02 BMW M3. "I basically got to the point where I needed to step up my game to be competitive in the show scene," he revealed.

Having built a steel grey M3 (et 1/07), Jeff got together with his friends at the tuner shop Carrozzeria Design and show team TWCompetition to commit the M3 to surgery. The first order of business was the rear fenders. "I wanted to keep them tame," he explained. "I've had friends who experienced problems with widebody conversions, so I decided to do the rears only. This way it's more functional, allowing more rubber on the rear wheels."

Auto Explosion in Gardena, CA widened the rear arches an extra 1.5" either side, while custom vents were grafted in as well. The new fenders matched seamlessly to the existing AC Schnitzer carbon diffuser, giving the rear more definition.

Otherwise, the exterior remained from Jeff's previous efforts with a molded Schnitzer front lip, shaved bumper lights, ATR carbon hood, roof spoiler and CSL-style trunk lid.

When it came to paint, Jeff rationalized a color change. "I wanted to paint the roof black for sure," he explained. "I was doing the rear fenders as well, so that's basically half the car. It wasn't going to cost much more to change the rest," he explained.

Jeff ditched the stock grey for House of Kolors white. "I always wanted a white M3 and the color I chose was based on the Lexus IS, but where the IS has a iridescent purple pearl, I used blue instead."

To compliment their work, Auto Explosion also disassembled the Brembo brake calipers and color-matched them in white as well.

The previous 20" Modulare wheels were scrapped in favor of new 20x8.5" front and 20x10.5" rear Modsport S1 wheels. "I wanted wheels with a sporty look and the mesh design worked well," Jeff stated. "I also wanted to contrast the white, so did them matte black."

A more aggressive offset gives the wheels deeper rims than before, providing ample traction with 285/25-20 Falken FK-425 tires on the rear.

With the star-studded makeover nearing completion, Jeff didn't want to neglect the motor. So he used his relationship with Active Autowerke to raise the bar on his supercharger kit. Having started with Active's Level 1 kit, Jeff was able to upgrade to Level 3, adding a front-mount intercooler and oil cooler, water/alchohol injection, new intake manifold and headers. He's since moved on to the latest Level 4 kit, which is claimed to produce 525hp and 338 lb-ft at the crank thanks to a larger 81-trim Rotrex compressor with 70mm pulley allowing 9psi boost pressure. Bigger injectors were also installed, along with UUC's stage 2 cera-metallic clutch and 8.5 lb flywheel.

The M3 was then strapped to the dyno, where the supercharged 3.2 liter laid down 432whp and 328 lb-ft of torque. It's just shy of Active's claims after calculating drivetrain losses, but doesn't take into account the 91-octane gas and warm weather, which may account for the missing power.

The rest of the car was left untouched because Jeff had mastered it on his first try. The interior still has Recaro Sportline seats in grey suede. Matching suede replaces the headliner, pillars, door panels and rear seats. Defi gauges are molded to the A-pillar to monitor boost pressure, oil and exhaust temperatures. A Schnitzer rollcage encases the cockpit, while attention to detail is seen in the carbon dash trim, ACS pedals, e-brake handle, floor mats and European center tray.

A wild show car wouldn't be complete without a crazy audio setup, so Lorenzo Dimichili of fabricated the appropriate system. Diamond Audio components adorned the front and rear, while two 12" D6 subs hang from the rear shelf. Four Diamond amps float on a custom rack in the trunk and the crossovers are mounted in the floor. A 15" monitor mounted inside the trunk lid complete the mobile boombox.

In his final year touring the show circuit, Jeff has managed to win several Best of Show awards at Hot Import Nights. Satisfied with his achievements, Jeff sold the car to move onto bigger and more family-oriented projects - he's preparing to buy a new house and is planning for kids in the future. A family-friendly E60 M5 also sits in his garage with bolt-on parts awaiting installation. He tells us he won't go balls out on the M5, but if history repeats itself we'll be seeing Jeff again soon.

The show must go on, as they say, and so that’s exactly what organizers of the much-loved annual Tokyo Auto Salon did, taking the 3-day event that usually happens in Chiba’s Makuhari Messe convention center and translating it (metaphorically, not literally; it was still largely in Japanese) into both streaming video and 3D.

Super Street: Anytime we talk about a vehicle prototype, the overwhelming response, once some of the initial smoke has cleared (and people are done cursing out the manufacturer and demanding that their design team be fired immediately), centers heavily on claims that the production car will look nothing like the demo car. In some cases,

You know the name Joel Tan (@jt_built) from his wildly popular SR20DET-swapped, ‘40s-era Willy’s Jeep that mingles among the top of Super Street’s most popular feature cars of all time, and we expect his 1972 Nissan Skyline GT-R and Toyota Trueno of the same birth year will also have a lasting impression. Both cars feature

The “most powerful 3-cylinder in the world,” applied to Toyota’s much talked about GR Yaris still sounds a little strange when you hear it, but you can’t deny the nasty 250+hp and over 260 lb-ft. of torque that are delivered through an eager AWD system, all packed into a relatively lightweight (by modern hatchback standards)

As if to pour a little salt into the wound that the hottest hatch in ages, the AWD Toyota GR Yaris, is not being brought to North America, the interwebs has begun to conspire against us by teasing us with modified versions from some of the biggest tuners in the biz. In December, those sneak
