standard should be 162. lowest is 121, any lower than that you'll need an engine rebuild. you should not have a difference of more than 15 between all of them. hope that helps

Can you elaborate? Do you want to know factory compression rate, top end and service limit of test with those pistons or your car specifically?

125
123
110

Yeah, those numbers are pretty crappy, but I had similar compression and drove for over 2 years without problems before I decided to put in a new engine.

Also, you'll want to get a leakdown test. It could be rings, but it could also be a head issue (IE: valve stem seals), which would be cheaper and safer to fix.

best thing to do is start saving here and there and take care of it then build it like theres no tomorrow. =) <-- going big or going home with mine...
