I searched for everything and couldnt find anything too specific. What is stock boost psi for a 94 twin turbo, and what is the max it could run?

 

10-8-10
the same for all years

not too sure but i think i read that the max the actual turbos could run is around 15psi. but don't do it unless you have proper tuning.

 

Max PSI the turbos are capable of is 27psi, although they are well beyond efficancy above 17psi.

This is what I have always read and have been told. I'm sure Majhik will arrive with the true numbers as he shares the same brainwaves as Re-Animemiya himself.

 

Actually if you want the turbos to last as long as it should. keep it 1.0kg^2cm or lower.

 

amd what does 1.0 kg^cm2 equal in psi?

 

I got a feeling that 1kg/cm2 will end up at around 14.7 psi

 

What RPM is the car SUPPOSED to hit full boost at? Supposing the boost is 10 psi.

 

Healthy stock Hitachis should hit 10psi by 3000rpm at WOT.

 

i thought it was 2800 rpms

 

Read where and told by who?!?

If you could sustain 18-19 psi to redline with stock twins, I'd be amazed, and they're running out of their efficiency zone at around 15 psi.

 

This might help......

EDIT:

Besides a good set of Turbos, other factors such as properly funtioning solenoids, wastegate, leak proof connections and correctly plugged vacuum hose system will ensure your 13B-REW will boost 10 psi at 3K.

 

14.22 Psi

 

Damn, im hitting 5 psi at like 4000 rpms. My car also shoots out a lot of blue smoke at start up... time for new turbos.

 

Check your WG/PC solenoid elec. connections. They may be crossed.
