At MotoIQ we have always contended that it is a much larger challenge to build an engine to hold up to the stress of road racing than nearly any other motorsports. For road racing or time attack an engine has to live despite being pounded on for many minutes at a time. A typical track session is 20 to 30 minutes long, way longer than a quarter mile or freeway blast. The continual stress of track driving is an acid test for an engine’s reliability, coolant and oil temps soar and the engine is run near redline for many seconds at a time.
A high powered road racing engine cannot be slapped together using cheap Chinese knock off parts bought on Ebay. The attention to detail required to be reliable in this environment is intensive. In our case we will be taking on one of the biggest challenges for the tuner, building a track reliable turbocharged engine out of an engine that was not designed by the factory to be turbocharged. In this case, every bit of the engine must be scrutinized for suitability.
Project NSX is the Brainchild of FX Motorsports Development, an NSX tuning shop whose time attack turbo NSX is currently smashing unlimited class records throughout the Redline Circuit. FX Motosports Development is transferring a lot of the knowledge gleaned from their time attack program to build the ultimate NSX turbo street motor.
The goals of our motor is to make a rock reliable 500 to 550 wheel hp on 91 octane pump gas with the ability to be track driven without missing a beat. Basically this engine is the same powerplant that propels Billy Johnson’s FX Motorsports Development NSX Time Attack car to over 750 whp on race gas. For our project car, big power numbers are just a turn of the boost control knob and a tank of race gas away.
