Tubular O2 Housing with Tial 38mm wastegate. 3" Downpipe, 4" intake pipe and of course a GT35R turbo. Fuel is again controlled by an AFC. NO NITROUS

The Head is ported with upgraded spings, retainers and valves. the motor is bored .02 over as well as the Block Being O-Ringed. Pretty standard motor build for us here at AMS.

We will probibly keep the car in its current tune untill a viable ECU solution is released. At that point larger injectors, timing control, and more rpm will make this thing unreal. The 6200 rpm rev limiter is absolutly killing the car at this point. Im used to GT35R cars revving to 7500 at the least.
