what is the compression on a 91si motor? i heard it was 125...am i hearing right? thanks in advanced.

 

I highly doubt that.
I just did a comp. check in my 90 DX last night and I was pulling solid 195's....I havent looked in my Haynes manual to see what the factory comp. should be my stock motor has 200,000 miles on it. I still have blow by though due to bad oil rings.
My friends GSR was sitting next to mine and we both had the hoods up and figured we'd do it on his car too and he was pulling 205's to 210's.....But his engine is in impecable condition...
