    Hey guys,

    I was wondering whats the highest you can safely boost on a stock GSR engine, with a little fuel management?

    0 psi.

    You need good fuel management like an FMU (shitty), a VAFC (not ideal), or hondata (ideal) and larger injectors to run any boost safely.

    The components will probably hold about 8-12psi, thats sort of the general consensis, but the HP goal means a lot more than PSI.

    consensus seems to be 300whp among the DIY crowd.
    Most ppl need 9-14psi to get there, depending on turbo size and efficiency, intercooler size and efficiency and competence of tuner.

    Power is a much better measure of stress on the motor than boost level. Read in the forced induction forum if you need to understand why.

    psi/boost is relative and in and of itself meaningless.

    stock gsr blocks can hold 300 whp with PROPER fuel management
    and 200-230 with hack jobs things liek fmus and vafc hacks

    without anything, it will hold about 1 psi and make 160 whp. the map sensor with throw a check engine light at 2 psi and retard your timing into oblivion, and you'll make 40 hp.

    way to cheap out

    I would expect 300whp out of a stock GSR turbo.
