Ok, I have a 03 350z greddy twin turbo on 7.5psi with 417whp and 390lbs trq. I am wanting to buld my car to have 600 to 700whp. And im wondering what can my car hold as far as hp goes. Like my axles, transmision, crankshaft, just everything i guess. I live in east Tennessee and I need to know what might be the closest shop near me to help build my car. Just if you can post some information to help me know what exzactly I need to do to get my car to these specs and still be driveable and wont be breaking down on me.
