You can keep the change.
Ok, so quite a few times ive hit over 40 lbs of boost with the fagtory turbo and head gasket. Thank god for no problems yet. It is my understanding that anything over about 40 psi with factory turbo/ head gaskets is asking for trouble. Im looking to add NOS and a few other goodies but before i do that id like to see what you guys thought about choosing a good set of head studs and what is a recomended head gasket to use to hold more boost??? Thanks.
