Hi there just wanting to know whats the limit of boost i can run the engine is stock just been cleaned new rings/bearings/seals and i have larger ball bearing turbos/nistune/555cc injectors.
Are your turbos hi-flowed stockies? If so 18/19 psi, if they're aftermarket and bigger possibly more.
They are not stockies there aftermarket that sort of psi wont lift the heads or break the studs it is a stock motor
Plenty of guys in the states pushing 500hp+ on a stock bottom end. What's your engine compression like? IMO depending on engine condition, you should be fine to see 300-330rwkw. Any more and you're playing with fire on a stock engine. Just make sure the tune is good!
