5 psi in 1985 , I beleive. At some point they switched to a T25 turbo boosting more , with a resulting 5 more Hp (In 1989 actually) .........
When I hooked my Autometer up to my car , it read 5 psi at full boost , so I'm assuming most Z31s are doing the same. Can't confirm it anywhere , however.
I will have to disagree with what JamesZ has said about boost pressure though , Z31.com states that 14.5 psi is the efficiency limit for the T3 , so therefore me running at 15 psi is not too far out of it's range. The stock limits are fairly high on everything , you should be able to get 270-280+ whp out of everything , this with no upgrades at
ALL.
