I'm even more lost now, why didn't you just say that in your first post? I'm not trying to be a know at all but the advise I gave you is pretty must srtaight foward. If your cars for the most part stock, your going to blow your shit up with a mammoth or even a f1a. I'm all about over kill but thats nuts! A d1sc is more the enough to push the limit of the 3 valve.... if I'm correct prochargers basic kit w/ the p1sc can make 400 to 450 ish, Why not just keep it?
