Well, I remember Ben's MR2 (turbo) is running 24psi with stock ZE internals and making over 200kw at the wheels, and he did 11.7 on street tyres. One of my mate is running 33psi on his stock ZE internals, but he over reved the engine, and kills the bearing, but the Piston/Rods are still in perfect. I belive they are forged, as long as you dont make the engine pinging and good tune. ZE internals will handle alot of boost.
