18253, max psi
Posted by ecl98pse, Mar-22-02 02:31 AM
what is the absolute max psi i can run on stock internals w/....
FMIC, 30lb inj., 6:1 FPR disk,
i know it's about 7psi for stock fuel sys., but not positive w/ this setup. I think it was around 10(i know it's hard on stk internals)
also what would it be if i ran race fuel?

The only thing i can tell you about this question, is that if you decide to venture into anything above 5 psi, make sure u replace the head gasket, it is the weakest part in our engine.
And it sounds like u'r getting up there in the compression, time to think about timing retart.

Stock fuel/stock internals. 10psi MAX!! It has nothing to do with luck, its making sure what your doing isnt causing any damage. Before you up the boost, do a compression test. After a week at the higher boost level do another one to make sure the boost isnt causing any damage. I raced a TT Supra a week ago with a couple mods (stock boost) and i was a car behind at 120mph...we started at around 50mph. I was running 5psi at the time.
