I have a 1990 Automatic GTU that I just got a full engine swap from a 1990 t2 with less than 60k miles on it, and i was just wander 1) What is the stock boost on it and 2) Wat is the highest recommended boost for a stock turbo?

 

Stock boost with the factory boost controller peaks at about 8 PSI.

With my supporting mods (see sig below) I'm running 5 on lo & 11 on high boost.
With the header dump open, it spools faster and I get 6 low & 13 high (14 on a cool morning).
The G-tech shows 220-233 net HP.

 

Thanks man, gotta question do you think at 10psi I could beat a stock 1994 300zx 5speed?

 

Maybe.

Driver skill could make the difference.

Cheat all you can.

 

I mean I think a stock 300 has 222hp plus he has a cold air intake which i 4got about so thats prolly 230, and if im not mistaken his car weighs about 300lbs more than mine, so im thinking it would be extremely close and would come down to drivers as well, which me and the 300zx driver are close in skill level...
