Meet Jeff Nguyen and His Dream NSX 

Jeff Nguyen, a 37-year-old entrepreneur and owner of Dis & Dat Auto Wrecking in Las Vegas, Nevada, has a lifelong dream realized – a meticulously crafted 1991 Acura NSX. A Honda enthusiast since his youth, Jeff's first car was a 1993 Honda Prelude, solidifying his love for the brand.

From Stock to Modern Marvel: A Vision Takes Shape 

When Jeff acquired the NSX, it was largely unmodified, boasting only a 6-speed transmission swap and an aftermarket head unit. His vision, however, was clear: to modernize the car and infuse it with an aggressive aesthetic, all while preserving the iconic NSX silhouette.

A Symphony of Carbon Fiber and Performance 

The transformation began with a striking exterior makeover. Fixed headlights from a 2002-2005 NSX replaced the classic pop-up units, with the interior housings painted a sleek matte black. JDM taillights added a touch of Japanese flair, while ARC Lighting LED boards enhanced visibility.

Downforce became a key focus, with a suite of carbon fiber additions including a front bumper, front lip, side skirts, side scoops, and a rear diffuser. Seibon contributed a carbon fiber hood, roof cap, trunk, and rear valance, further emphasizing the lightweight and aggressive theme. Pride Carbon wide front and rear fenders widened the wheel arches, creating a more muscular stance. Wings West side skirts and an APR front carbon splitter completed the lower body transformation.

Ronne and Lou at TCM Japan supplied Do-Luck mirrors and a spoiler, adding a touch of racing pedigree. The meticulous attention to detail is evident in the custom paintwork by Ray and Raul at Evolution Auto Body. A unique fading effect on the hood and trunk seamlessly blends the red paint with the exposed carbon fiber, showcasing the extra touches that elevate this build. Andrew from BX Built completed the exterior transformation with color correction and a CarPro ceramic coat, ensuring the paintwork remains pristine.

Honoring the Honda Legacy: A Naturally Aspirated Powerhouse 

Jeff's passion for Honda's high-strung naturally aspirated engines remained a core principle. He opted for Science of Speed's Individual Throttle Body system to enhance performance without resorting to forced induction. This upgrade stayed true to the spirit of the original engine while adding a touch of modern refinement.

The centerpiece of the engine bay became the custom titanium velocity stacks crafted by Mazterpiece Automotive. These not only enhanced performance but also added a visually stunning focal point. A PasswordJDM Integra intake tube provided fresh air, while Injector Dynamics injectors ensured proper fuel delivery. Pride Exhaust headers and custom straight pipes channeled exhaust fumes, culminating in a powerful roar from the ARC titanium muffler. An AEM Series 2 ECU kept everything in perfect harmony.

Gripping Performance and Luxurious Comfort 

Brian at Mackin Industries played a key role in selecting the perfect wheels – a limited set of TE37 Saga Time Attack wheels that perfectly complemented the car's color scheme. Sticky rubber from Toyo Tires provided exceptional grip, while Rotora's front and rear big brake kit ensured impressive stopping power. Tein Flex coilovers with air cups on the front suspension allowed the car to maintain a low stance while navigating obstacles.

Further enhancing handling, every available chassis brace was installed, including Foundry3 Titanium Rear Strut bar, Route KS front strut bar, GT Spec front and rear braces, Cedar Ridge tunnel brace, and STMPO front chassis brace.
