Hey guys i just put an rb25 in my r32 gtst and i've made some good numbers but want to know how far i can go. I'm running a stock head gasket with arp head studs so i'm good for lots of boost. And i have factory internals. Now how much boost can the internals handle cuz i know i won't have to worry about the head lifting and the gasket blowing out with the arp head studs? And i'm currently making 400 wheel hp on a mustang dyno with 20 pounds of boost. How much more can i make before worrying about internals?
