1991 Acura NSX - Marriage Proposal Included (For Real)

NorCal native Kris Yu reps hard with one clean NSX & pops the question in the Special Thanks section

1991 Acura NSX - Marriage Proposal Included (For Real)

Kris Yu is has been pumping out quality cars for years. After building a 911 Porsche, he wanted something exotic and high end without the headaches and maintenance that come with some Euros. His latest creation entails Honda's legendary supercar, the 1991 Acura NSX, short for New Sports car eXperimental. And even today, after 20-plus years, it's still the dream car for many Honda junkies. [side note: Yu proposed to his now fiance in the "Special Thanks" portion of this article, when she saw it in the Nov. issue mag, she said Yes!]

Believe it or not, this car was a culmination of three different NSXs. His first NSX was purchased from Fatlace and Illest creative director Mark Arcenal. Kris loved this NSX simply because it had a built transmission by HKS and was the #16 NSX off the assembly line. The second one he bought had a solid interior and a JDM motor with only 7K miles on the odometer, however, its exterior was a bit deteriorated. Kris eventually bought a third NSX (Is this guy crazy?! -Ed). There was now a trio of NSXs parked in his driveway. The third one was decent in terms of interior and exterior. After much weighing the ins and outs of each car, Kris decided to keep the second one because he knew he was going to make some major exterior changes anyways, plus the motor was sound with its low mileage. "I didn't want to cut up a perfect NSX body. I figured I'll let someone else enjoy it," he explains. The other two were sold after Kris picked out all the little pieces that he wanted to keep, such as the OE door motors, interior panels and window switches.

An interior so damn clean even all the aftermarket stereo equipment looks OEM or is hidden from view.

When it came time to build his masterpiece, Kris tackled the exterior first. He didn't want to make it impractical to where the car wasn't capable of daily driving. He noticed most NSX builders either kept the body stock or went to the extreme. "My only rule when I started this project was to not take away from the lines and true look of the original exterior." It took Kris roughly a year of planning and piecing together the aero till he was satisfied with the look he was going for. The result is what he calls JGTC-inspired. It features a custom widebody mixed with some JDM and USDM pieces. Front and center, you'll find a very sexy JDM Burn Up front bumper, followed by an array of Downforce aero, including the side skirts, engine ducts, rear fenders and intake scoops. For the rear, Kris took the stock NA1 bumper and cut the lower half so the exhaust was visible. He then rolled the edges and molded side splats from Backyard Special. Perhaps the hardest part of the project was the subtle widebody, though. It might not scream widebody, but each corner has brand-new aluminum fenders. The fronts are 1-inch wider per side, while the rears are 1.5-inches beefier.

Next up was the NSX's chassis. Prior to his current setup, a set of NA2 Type R suspension was used. However, after going for a test ride with air suspension, Kris knew right away this was the route to take. AirREX made a custom-valved setup just for Kris and guaranteed it wouldn't stray away from performance. "I was worried that after I installed the air it would feel hella floaty, but it actually handled better than my Type R setup," Kris says. (How do we know he's from NorCal? Hella! -Ed). Finishing up the chassis upgrades included StopTech big brakes and sexy 'n' staggered Work S1R wheels.

As we mentioned earlier, this particular NSX only had 7K miles on it. Well, it's because the motor was previously swapped from its original '91 engine to a reconditioned '95-spec. It features upgraded cams and valve springs, plus Kris added bolt-ons such as a Pride header, test pipe and exhaust to let the six-cylinder breathe. To keep up with the extra airflow, injectors were upgraded before a Prospeed ECU was used to tune the car to 287hp—not a crazy amount of horsepower but enough for this mid-engine supercar to have some fun.

Low-mileage 3.0-liter features bolt-ons and upgraded cams to make 287hp on pump gas. Not hella bad…

Attention to the interior was just as important to Kris. Holding him and his passenger are Bride Digo seats strapped with Takatas. Even with all the custom exterior and top-shelf parts on the car, Kris tells us he loves his stereo setup the most. He was going for an OEM-classy look, but nothing extreme. The custom center double-din dash holds the Clarion DD and 7-inch monitor. All the other audio gear was hidden away from sight.

There were a lot of options that could've been done to make this car appeal to the younger and trendier crowd. Kris could've easily painted his NSX a flashy color, but he went with a more modest black. He could've turbocharged it, but he'd be dealing with tuning issues. And while his car may be on air, it's not obnoxiously slammed and allows him to drive around town with ease. You can always do what people on the Internet tell you, but having an NSX this sweet that you built using your own ideas and inspiration can't be beat.

Special Thanks I would like to take this time to thank my girlfriend Tammy for always putting up with my hobbies, the countless hours you stayed late while I was working on my cars, waking up early to keep me company at shows and flying around the country for events. I would like to make this feature special to you as it is to me. I'm glad to have met you and I don't know what I would do without you. Will you marry me, Tammy? Now turn around...
