Advance Co Crafts 343 WHP NSX
While most choose forced induction as a source of additional power, ADVANCE Co. chose to keep things naturally aspirated, focusing on improving the NSX in every way imaginable.
Improving Upon Perfection
The original NSX platform has undoubtedly stood the test of time. The factory engine's output may no longer be considered exceptionally powerful by today's standards. But it's still plenty to allow for a joyful driving experience. For many, upgrading the power plant is a natural first step toward improving the mid-engine Honda. For Susumu Shimbori and his team at ADVANCE Co, however, enhancing the NSX has been about a lot more than just the engine.

Power Upgrades
The folks at ADVANCE approached the power upgrades for this build with durability and reliability in mind. That's why they chose to stay away from forced induction. Instead, they went to work upgrading and fortifying every element of the V6. This included the incorporation of items such as higher-flowing C32B cylinder heads, TODA Racing camshafts, and prominently, an ADVANCE individual throttle body system.

Naturally Aspirated Power
These upgrades result in reliable power and a more consistent delivery curve. Further improving airflow out of the motor is ADVANCE Co.’s FLAT OUT exhaust system, which comes with high-flow catalytic converters and titanium pipes. With all the work done, the NSX was clocked on the dyno producing 343 horsepower and 246 lb-ft of torque, which is a decent bump from the factory 230 horsepower at the wheels.

Body and Aero
As we mentioned, this build is about way more than just power. Shimbori-san's goal for the project was to optimize the platform's performance on the street as well as the race track. The addition of body modifications and aerodynamic elements was a no-brainer. And there's plenty of that in play with this build, most notably ADVANCE's application of a wide body kit.

All About the Details
Numerous subtle aerodynamic upgrades have been engineered into the kit to help improve air flow, reduce drag and lift and provide additional downforce. Sophisticated ducting in the wheel wells plays a huge role in that. Speaking of the wheel wells, the wider track has allowed for the incorporation of wider tires, improving mechanical grip. And while we're down there, let's not forget the addition of 4-piston AP Racing brakes.

Lapping Fuji Speedway
The final product was thoroughly tested at the world-famous Fuji Speedway, where the ADVANCE HSCC (high-speed circuit challenge) is held. The event invites drivers to put their street cars to the test at the track, with a chance to earn recognition in the “Under 2 Minutes Members Club.” The NSX project set an impressive lap time of 1 minute and 56 seconds, a huge improvement on the factory car's 2:20 time.
