Silvia Club of NSW

Ok I seem to have been mis informed here and am just trying to work out my boosting levels to see if theres something wrong or not.


Can someone please tell me.

What psi is factory for a 91 s13 silvia sr20det ?

I have been told, 6, 7, 9 & 10. Which is it?

Thanks guys.

Aaron

from what i've read.
7psi is standard.

though some specs say 6psi is standard

Officer ! I swear its all factory standard.

Depends on the weather. Your boost will very depending on relative humidity, air temp and atmospheric pressure.

Factory standard you can expect anything from 5 or 6 up to almost 8 psi.

If you add an exhaust and pod filter, a cold, low-preseure day can produce anything up to and around 12 psi of boost.
