Anyone know how much a rotary compression tester cost? and where i could get on at? thank you

 

holy crap never mind that thing is dam expensive, anyone know how to test thier compression without a rotary specific tester?

 

Get a regular piston compression tester and take out the valve which keeps the max reading. Then you can watch the compression bounce over the 3 rotor faces. Or you can just take it to the dealer and they can put it on the real mazda tester (if you're dealer is any good)
