you are going to blow your car up..

An intercooler is not NEEDED but its highly recomended, do you have any injecors,fuel pump or anything? do you have any intercooler piping? anything to tune with (such as safc or w.e they use) ? do you have a manifold? a downpipe? By the sound of it, I think you will like the greddy type S bov and any wastegate will work for 8 psi on that car.
