Stock Nissan Boost?

[reNEGaDe88]

Hey guys. I have been wondering for years and still couldn't find exact figures.

What were the stock boost levels of the good nissan engines?

Like the R32 GTST dash only goes up to +7psi for the RB20DET

Wikipedia says the RB26DETT were limited to 10psi stock, but would run 14psi otherwise.

What about the SR20's and CA18's?

Cos I wanted to compare Nissan engines to the Subaru Sti engines and the Mitsu Evo engines.

All smallish displacement turbo engine as compared to the big V8's

Thanks in advance.

the stock boost gauge isnt in psi, its in mmhg with +7 being close to 1bar i think

mmhg is millimeters of mercury. 1 millimeter mercury (@0°C) = 0.00133322 bar, or 1 mmhg = 0.019336721 psi.

I wonder why nissan chose to use that form of measurement...

mmhg is millimeters of mercury. 1 millimeter mercury (@0°C) = 0.00133322 bar, or 1 mmhg = 0.019336721 psi.

so +7 on the stock gauge is 0.135psi?

mmHg is only used in VACUUM.

I can't remember what the positive pressure side is measured in.

But the GTS-t RB25DET R33 runs 7PSi max stock.

Cheers.

So would the R32 RB20DET also run 7 psi max stock?

The RB30ET's ran 6 psi max stock I thought...

Please use the search function.

Stock specs, basic mods and so on are very well covered

4mmHg ~6psi

R32's stock run a 10psi actuator.

This is all covered, and i think also just 2 days ago
