Chris.

Just have the present owner take the car to a local Mazda dealership for the compression test. The rotaries use a specific compression tester. You could use a typical compression tester for a ball park test, but I prefer the Mazda tester. Ask the dealership to fax you the results. The test should cost around $100.

fwiw, the compression specs for a 93 or lower than the 94 and 95 model

i just want to make sure that the dealer is competent in doing this test, should i follow the 94-95 specs of 85 psi, or the 93 spec of 85 psi?

I believe that most Mazda technicians should be competent enough to perform this test. I aasume you have heard/read horror stories about the dealerships, but this is a relatively easy test.

I don't have the specs nearby, but I if I recall correctly the min for the 93s was about 90 psi and the min for the 94-95s was approx 105psi. There is also a max delta between the peaks that you need to be concerned about. The dealer should give you all this info with the test results.

good luck
