Now my true noobness shows..
Ok So my Jspec s5 t2 motor is sitting on a pallet in my garage. Decided to check compression on it. Now I know I don't have the mazda tool but I have also read many of you don't use them anyway. I also know that to get a true reading the motor needs to be up to operation temps ect ect.. But I figured I could get an Idea of what I was looking at as far as if I needed to rebuild right away. So I hooked my battery up to the harness and turned the motor over And tested the rear rotor first and I did the surge test first and it was right at 85 psi everytime the needle surges then I let go of the button and within the first 3 or 4 surges it went straight to 110 psi Then I did the same thing on the leading plug same readings.
Then to front rotor, and nothing. Zero!!! Any Ideas?

Inspect the apex seals through the exhaust first. If they are intact and go ahead an spin the motor up. Drop some oil inside the chamber. check compression from the T plug holes. Cold you should see at least 75psi on all faces. It is not uncommon to find a 100psi on one rotor and 75 on another if this is the running case expect it to blow.

Shh.. dont say that, Our poor poor track...
Yeah I was thinking about rebuilding anyway. The guy I want to send it to is in TN, so I may just attempt it myself...
