94k 180 compression?

[97gsssst]

I recently bought this gst and it has 94k miles on it. So the other day I did a compression test on it and it was about 178 to 180 compression across the board. I have owned one first gen and the compression was like 75 across the board and it only had 100k on it. So the question is could a normal 7 bolt engine with that many miles on it still have perfect compression without being rebuilt? Thanks.

I recently did a compression test on my 87k mile motor and it had perfect compression so I don't see why not.

Yes. If the car was well taken care and not driven around constantly boosting it. Or the motor was replaced or rebuilt.

My Talon has the same #'s across the board also.

As done mine with 215,000kms

Anything much higher might indicate some combustion chamber build up that might need some cleaning out.

Also 1G stock compression is I believe 165, 75 is very low. 120 is the service limit on 1G's, but I know of a few people with the compression you got with high milege engines on 2G's.
