Well i decided to do a compression test today to see how my car was doing. I was a little shocked at the outcome. I got a reading of 160-180-160-180!!! Im not too sure but i think that this is a little high. I have a pretty much stock d15b2...i read on here a while back that it should be somewhere in the 130 range across the board. Does this seem a little high to anyone else??? What is it supposed to be on my d15? If this is high what could be the ptrblem and what damage could it cause...if any? Thanks.

the high numbers just means that the rings are still good. I don't know what the exact #'s that motor is supposed to be but your fine.

 

look in your manual to see what the numbers should be, it will also list a maximum differential pressure. My compression numbers on my z6/a6 piston combo is 217 across the board. I verified three times.

i checked the helms for you and nominal is 185psi, minimum is 135psi, and the max variation is28psi.
