100psi on both rotors at 125k?
I did a compression test on my motor today, admittedly the motor was not warm, but I got between 95-100 psi on both rotors for all three pulses. This is much better compression than I thought it would be, and suspect it was rebuilt at some point. My oil pan has a mazda reman. sticker on it as well, but I thought nothing of it because there were two stickers. Do you guys think it may have been rebuilt?

It's really too hard to say just on compression numbers. Just be glad they're good!
I have six identical 95psi pulses on MY original engine and the mileage is basically twice what yours is.

Must be those super high compression rotors from ebay! :P
JK, Those numbers are great! You did modify the check valve in the compression gauge or atleast tapped thre pressure relief button in right? If no, then you could get higher then norm compression numbers.

Yea, just held in the pin. I was pretty surprised, I have been thinking about the N/A->TII swap, but I think I may just end up selling my car and buying a TII. I guess I can wait for a while on that, meanwhile I've got emissions right around the corner...Oh well, good news, thanks for the responses guys.
