Re: 300zx twin turbo max boost
stock turbo's max out around 16-17 psi... but i wouldn't recommend pushing them much harder than 15 on a normal basis...

yeah, fuel injectors cant handle much past 15psi. once you upgrade those you could probably max out the turbos but i still wouldnt recommend it for standard driving conditions.

Re: 300zx twin turbo max boost
when runing 1/4 mile ive seen guys running 18psi with ported turbos on stock injectors but i wouldnt recomend doing without risking damage
i run 15psi consistanly n havent tried to take it up yet, with the injector up grade i think you can run up to like 22-24

stock turbos start losing there efficiency maxing them out at around 17-18psi...so with upgraded fuel injectors you could possibly run 18psi but once passed that your looking to deteriate the life of your turbos drastically, if the engine withstands the power. i personally would leave at about 12 or 13 psi and take up to 15 psi when needed...but i like to play things safe because bad luck seems to be my shadow.
