I would like 50rwhp more out of my s2 R33 gtst and would like suggestions on how to achieve it.
I was thinking custom exhaust manifold + plenum like what Brendan had done to his car. One mechanic said it would cost me about $5k.
Currently I have 3" exhaust from turbo back, POD without air box, high flowed turbo, hiflow cat, EBC set at 0.8bar achieving 252rwhp, heavy duty clutch, fuel pump, adj regulator, powerFC, adj cam gear and I think that is about it.
