5SFE Compression Numbers, Post yours, heres mine- Options

[Silver94CelicaOw...]

I finally bought a compression tester the other day, and got results for all four cylinders. Cylinders 1-4 all check out very consistent and even all the way across, maintaining around 180-185psi after several cranks of the piston reaching TDC. My battery isn't the greatest so it may not have been cranking at enogh RPM's to see proper results.

For reference, I wanted to get a little compression comparison going on so that I can get an idea of what people with healthy 5S's are running. I'm doing these checks to determine whether or not to lightly boost what I already have or to go for a newer 5SFE before the project begins.

Post up figures if you have them, otherwise let me know what you think of mine and what route I should take with the motor.

Manny thats good news to me. I couldn't for the life of me remember what the numbers were on your motor. I knew they were excellent though.

High miles Art....like probably somewhere in the neighborhood of 175-180 grand. Thats my primary concern, however the motor runs amazingly well. I've been running synthetic for over a year now and it seems to run just as well if not better than it did when I first bought it four years ago...very smooth. Thats not to say that it wouldn't pop under boost, but it seems like it'd be capable of running very strong for many more years to come.

Can u guys explain the procedure of a leakdown to me? I've been told before as well as read that it will give you a great look into the condition of the motor, but never knew what is involved. You compress air into the motor and see how quickly it leaks or something?
