[Italipalm]

just outta curiosity how much boost can a 99 gst motor take on stock internals w/o damaging the motor

Depends on your turbo and supportting mods.

24 psi with race gas is the limit on a stock motor

6Bolt motors will hold a little more. I know guys, including myself who run over 26psi on stock 6-Bolt motors, of course thats on the ragged edge, on race gas, with plenty of fuel tuning.

The larger the turbo the less boost but with any of the normal "street " turbos 25 is the max I would go on race gas. I have seen some peaople run 27psi and I have seen someone snap an rod on 29psi.
