Cylinder compression for a 1990 Chevrolet Beretta GTZ?

Question

2.3 L Quad-4 (High Output). What should be the compression rating........not the ratio, I have those numbers!!

Thanks

Answer 1

I really wouldn't know with that, so im taking a guess, but it's an educated guess. i would say anything from 120 to 140 would be fine.  make sure they are all in the aproximate same rating.

Answer 2

140 plus or minus 10% max. higher then 170 is carbon, lower then 120 rings or valve.

90 or below...sell the car...that should show up at idle.
