Hi guys. I'm building my first turbo car. My intent is to turbo a bone stock '94 GT minus emissions equipment. I'll be installing a larger in take pump, blow thru MAF and 80lb injectors. I've read and heard that I should run head studs and better valve springs in the E7 heads. I've also read that the heads can still lift with studs and that the stock valve springs are fine. The engine has 53k original miles for reference.
