I just had the compression test done for the 91 NA that I've been looking at, here are the numbers:

this is done with a Mazda compression tester.

rear rotor:
8.2, 8.1, 7.9

front rotor:
8.4, 8.3, 8.1

these sound like awesome numbers, what do you think???

 

Those are pretty good. How many miles and is that the original engine?

 

the guy at Rotary Performance in Manassas VA (Bret I believe) said it's probably a new motor when he was doing the test...

 

oh, and the odo on the car says 116k...
