Default 03 EJ205 Compression test results @ 165K

Just finished doing my compression test and here are the results!

Was done on a warm engine following the FSM's instructions.

Cylinder 1: 160 PSI
Cylinder 2: 161 PSI
Cylinder 3: 160 PSI
Cylinder 4: 161 PSI

FSM says 138-166 PSI is standard so needless to say I am very happy with the results! I even went back through and did the test twice to be sure.

Just posting this up here to see what others are getting as far as compression numbers, I've seen a few but please post up your year/mileage/compression results if you want!

I will change it to EJ205 if it will make you feel better.

Well I wanted to check it just to give me piece of mind because I am about to be upgrading the turbo and shooting for 300 wheel. These results make me feel a lot better about going ahead with it!

OP you are a lucky man, as of two years ago my compression test would have shown something like 150, 155, 0, 158

I broke a rod in to pieces....
