Actually his car should have a TREMEC 3650 trans. I would say use the trans unless you can upgrade to a T56 (03-04 Cobra trans). The king cobra clutch will for sure give up on you if your running those numbers. I can tell you from experience the Centerforce DF clutch will give up around 550 RWHP. I went with a DFX clutch from centerforce and I haven't had any problems so far. Its reasonably priced. About 500.00 for clutch kit and TB.

Let me know how that thing runs when you get it all together.
