How much boost?
 

Hello,

I just recently acquired a 1990 300ZX TT and she is running at 10PSI. I was just wondering, how much boost can she handle with stock internals and stock turbos?

a bit more...
 

I was running at 15 psi peak stabilizing at 13 psi after 4500 rpm with a complete exhaust and a front mount intercooler ( all my piping was in 2.5 inches steel tube). 346 hp on the wheels and 393 foot-pound of torque on stock internal, turbos and injectors. You'll need a good air filter upgrade, much more fuel pressure ( 70psi with boost) and someone who can tune it ...
:icon_super: made 3 summers before blowing a head gasket... Of course, I'm doing drag racing and time attack so the stock internal is pretty strong.:023:
