This sunfire has a 2.4L turbo charged DOHC with an inter cooler. The cooling system has been modified to keep the engine cool. The exhaust pipe has been widened to 2" with duel euros. We installed a race tuned ECU. It has topped out at 148 MPH. It has won races against honda's and mustang cobras. Thats all we can tell you.
It is the lead car of a unknown and growing car club.
