However the owner of the car wanted to go with the Greddy system. I was able to get him a good deal on it so its not like its a bad deal. Also considering you cant really touch the power any turbo system cam make for the 350Z with out building the bottom end first. Correct me if I am wrong but the TT ASP, TT JWT and TT Greddy systems are capable of producing 20 PSI + its just too bad anything more then 8 psi on the stock engine and your in for a bad day if you on pump gas. I have already informed the owner it will be fast but not to get stupid with the boost on stock internals.
