compression test is just about removing spark plugs, removing fuel pump fuse, putting a compression tester in each spark plug hole and try to crank . Repeat for each cylinder, and do it with throttle fully open and battery fully charged. That is a dry test.
If results are low, do the test again but add a spoon of oil in each cylinder (by the plug hole) before testing. That is a wet test. If results are now good, your rings are not sealing anymore (means dead rings, or worn pistons/ bores).
A compression tester is worth maybe 20$, get one.
Another cheap thing to get is a product you add to a sample of your coolant. If it changes color, exhaust gases pass through your coolant (which is bad).
riced => ask google, he will tell.
You wont find a decend SR20 that does not need a rebuild, really.
