R32 std boost on Australian delivered car

page EN-23 in workshop manual

"remove the intake manifold canister hose, place a cap on the hose, Connect test hose to intake manifold and attach pressure gauge.

"when engine operation check is performed check the pressure does not rise above 0.8 to 0.9 kg/cm^2 (11-13psi)"

In practice mine runs 8 psi with stock exhaust and 10.5 with a cat back

Hope this is of some help

Cheers Alex

mine ( r33 gtr ) runs 14.5psi with turbo back exhaust on stocc boost solinoid , 4th gear uphill it hold 15 psi . i have an engine manual but it doesnt specify how much boost it should have . it does say at what pressure the actuators should open the wastegate and thats within specs . just wondering why it boosts so high .

8 psi thats a bit low alex , i thought around 12 but r32 may be different to r33 .

My car was a dead stock unit when I brought it in from japan. Stock airbox, exhaust, like it was just from the factory. It was making around 6-7psi, then I added a cat back exhaust and it picked up to about 8psi. I then put in a ebc and ran 12psi on the stock turbo day in and out and I sold it when I upgraded to the td06. The turbo was still in excellent condition, thats about the max boost I would run on a day to day basis on the stock unit.

rob77 was that a gtst, rb25det or gtr , rb26dett ? stock gtrs run a lot more boost like 11 - 12 psi i thought ( thats bog stock ).

mine will hold 15 psi on 4 th gear uphill no probs .

Would this sound right? on my car i have cat back exuast 3 1/4 inch.. with pod filter and heat shiled..all stock and im getting about .5 bar and then at 5000 rpm it boosts to .7 bar.. so from about 7.4 psi it goes up to about 10 psi at 5000.. is that normal for r33 gtst.. its a 05 model with series 2 engine..

sorry 95 model series 1 with series 2 engine

shorty, that is about right for R33 GTST's.

Both the R32 and R33 GTR runs 9psi in standard form.

Not too sure about R34's.
