I would check and make sure what block you have before you do anything to it. Its not worth spending money on the turbos if the block is sh**.

anything over 35 psi on a hx35 is just hotter air. boost is not power it is a restriction. Mass of air = power. colder air=more power. pressured cold air is what you want. I occasionally get to 45lbs.

Studs are about $440 and require several re torques to maintain integrity.
