R32 Gtr Boost Levels

[daniel55]

Hi all!

Just traded in my R33 GTST, and have bought a R32 GTR. I was Just wondering what the stock boost level was for them? Is it the same as a r33 gtst @ 7psi?

none run 7 pound.

target boost is 11-13psi

Now I know this may seem like a real silly question... laugh if you want, but..

What are the stock actuators set at? I have an old blitz twinsbc and no longer have any of the original boost signal lines or solenoid, including the yellow band restrictor.

With the unit turned off boost sits almost neatly on 0.5 bar.

Is this what it should be?

Stock boost is 0.75 bar apparently, contolled by stock solenoid and restrictor in vac line.

^^ what he said, take the restrictor off it runs about 0.95-1bar. recommend you dont do it but untill u have aftermarket/steel wheeled turbos. gtr should be enuff power to blow u away from a gtst upgrade (assuming it was stockish).

bar/psi conversion anyone?

*takes one for the noobz*

[GTR1993]

1 bar=14.5 psi

No one knows?

Yes I did search, but the only answer given is that stock gtr is ~10psi, but that is with the stock solenoid and restrictor..

the factory wastegates/turbos are at .5bar. but with the factory set up target boost is 11-13

Thanks champ. Considering how bodged all the systems on this car are, it is nice to know that some things are right.. just need to know what they should be.
