I am working on a Ls/vtec turbo set-up, and I have an b16 already in my rex. I was wondering if I need to upgrade my clutch disc from my ACT street/track disc to a ACT 6 puck when I swap motors? I already have a heavy duty pressure plate, and my goal with the Ls/vtec turbo is 350hp-400hp. Any suggestions?

 

Yeah, don't do a Spec.
