Oops, compression ratio for the S-body SR20DET is 8.5:1. The GTi-R SR20DET is 8.3:1. You can click below for specs on various SR20DET engines

However, I have to now assume you are wanting the compression in psi for each cyclinder. If that is the case...

Optimum - 179psi / cylinder
Minimum - 151psi /cylinder

Here is a useful link on how to check compression: http://www.240sx.org/faq/articles/compression_test.htm

Those number are for KA24DE...


For a SR20DET, me and my friend are getting around 120 ~ 130 PSI

Hey Thanks for the mush needed info!

Hopefully my 91 piece of crap 240sx will get a sr swap later this month!
