I want to do a compression test on my motor to see if I need a rebuild or not. I was wondering if I need to have a rotary mechanic do it, or if a compression test could be done by any mechanic? I was also wondering if it does any damage to the motor?

BTW, I did a search and couldn't find anything.

oh, and check out this video, its pretty funny

Procedure for a 3rd gen is (page C-11 RX-7 Workshop Manual:
1. Warm up engine to operating temperature, then allow it to cool for 10 minutes while you get the plugs out.
2. Remove the front and rear trailing (upper) spark plugs while the engine cools.
3. Disconnect the circuit opening relay, and the igniter connector. The CAS and EGI fuse are both unplugged so that no gas nor spark will occur during the test.
4. With both spark plugs out, fully depress the accelerator pedal to the floor, and motor the engine for 5-10 seconds. You should watch for 3 bounces of the needle (once for each rotor face). Specifications vary depending on the brand of shop manual. I’ve gone by 7.0 kgf/cm2 or 100 psi minimum @ 250 rpm as stated in my 93 RX-7 Workshop Manual. Other references say 6.0 kgf/cm2. Yes, you can compensate for higher cranking rpm during the test. There's a chart in the Workshop Manual.

20+ for a pressure tester.
a certified mechanic ASE or a shop specifically on rotory
gota love copy and paste.

lol @ the clip, i think that would be a innovation of speed ticket
