Compression question
 

http://www17.ocn.ne.jp/~rx7_fc3s/spec/rrotor.jpg
Does this car have 3 rotors???If not can someone explain how to read this compression test and what are the best numbers for a FCs T2 engine.

im sure that shows the compression for the 3 different faces of the rotor.

Uh huh. Good numbers, too.

Those are the readings from the 3 faces of one rotor, and those numbers indicate that the combustion chamber tested is virtually new. Those are very good compression readings, just hope that the other rotor is as good.

I wish mine would have been like that, I got 6.5-6.9 on both rotors.

wuts the best compression possible? How much does a comp test usually go for. Also is it really hard for Average condition T2s to pass CA emissions?

damn those are really good compression numbers man, the highest is 9, man i hit 6.7 on the front rotor and on the rear 0-0-4.7. I'm just curious how many miles are on that motor?

Download or buy the FSM and it'll answer your questions.

doesnt 0-0-4.7 mean you have a blown seal or somthing?
and to test both rotors you put the compression tester in the front and back lower spark plug chambers right?

seriously tho say it was a rebuilt t2 motor..would it have problems with smog or just be splitting hairs?

Is it now, or will it be, connected to an exhaust system with a catalytic converter? Are the OEM emission-control components still in the car and operational? Are you running the OEM computer? If so, you should be OK.

how much does a compression test and full tune-up go for on average? Also is there any Rotary Performance shops in the Nor Cal area??

hmm well everyone in nor cal bay area knows about ricks rotary in pleasanton haven't been there myself, but i might stop by in the future

Thats a bit strange.

The faceplate says the unit of measure is x10 KPA.
kPa x 0.14504 = psi

So 90 x 0.14504 = 13.0536 PSI.

That alone confused me.

Another consideration is a genuine comp tester reads in kg/cm2 (bar). So it would be misleading to compare numbers off this meter with numbers off a genuine meter.

Move the decimal point to the right. 1kPa = ~ 14.5 psi.
