Just finished building my new engine guys :)

Has anybody got any compression test results of a stock n/a?

This is a cold engine btw.

My previous swift gti's had 210psi comp pressures. Is this on your starlet n/a car. I never done the test when cold, so i dont know what figure you will see when its at hot engine temps. If it goes higher, it would be considered near a diesel engine i guess, dunno.

Every time I see a thread about cylinder compression on this site I always get confused. I have never seen a starlet make more than 145 psi across the board. 210 is unbelievable :eek:

Thats a bit more like it, i assume that was on a reasonably fresh engine. I have only done tests on well worn engines tbh but 210 seems excessive to me. Can you tell me what the cc volume of each chamber is on the heads as standard?

On my bog standard 60k 4EFTE I got 180 on 2 cylinders and 185 on the other 2, this was from cold after being run :). I was told that was pretty bloody good!
