Thanks again for all the replies.

2 psi means around 60 RWHP, and like Peter ( from APS )told me once: "I advise all 350Z TT owners to limit the power to around 380 whp if engine longevity/relaibility is high on their agenda" . If you are thinking in more than 400rwhp with stock motor , then you can expect anything................like me, my stock head gasket blows at only 7.5 psi.
