No need. My internals are good up to ~550awhp. Weak point for the 4G63 is the rod bolts at that point. Only thing I had to do to run 30psi was install ARP head studs.
ARPs are an easy and recommended upgrade for Evos running over 25psi on the stock turbo or running aftermarket turbos.
EDIT: Do want Robispec. Will be buying in about a year and a half. OMFG do want.
