Does anyone know the factory stock compression numbers on the 02 WRX?
Mike
The shop manual says 8.0:1.
CR = 8.0 is correct... 8.5 is too high for a turbo motor that runs 14 pounds boost.
Or, did you mean what is the normal PSI for a compression test? Common question after someone cooks an engine by using a manual boost controller.
Spud.
Yes, that's what I was asking, normal PSI for a compression test.
Thanks,
Mike
Are you looking for the compression _ratio_, or the actual pressure?
Shop manual says 142 PSI to 171 PSI @ 200 to 300 RPM
