Is there a way to do a compressor test with engine outside of the car?

No flywheel on the motor? If it is, you could make a quick fixture to hold the starter in place and crank it. I had an old RX7 12A motor that I was able to compression test by holding the actual starter by hand while my dad cranked it and watched the compression. But those motors are extremely easy to turn over… so I was able to hold the starter without any issue…

You know why your dad told you to hold the starter?

:shifty

rofl:rofl:rofl

I’d imagine on those little rotarys its not to bad, can’t imagine trying to hold a starter on most engines though
