Default compression test results. ok for boost?

It came out 180 180 210 210. then i put in some oil into the 180's and it was 215 185 (probably higher b/c i didn't even put a half cap full). So the piston rings are bad?
Think its still ok to boost? only 36k miles on the stock engine b18c1.

Check your valves, maybe something might be wrong with them.

no nitrous, its stock.
compression test with a compression tester, i don't know any other ways to do it than the spark plugs out, fuse out, and test.

Are you opening the throttle body all the way?

not one cylinder should be lower then 15% of the highest number you get.. in your case, its 210, so 15% of 210, is about 31%, 210 - 31 = 179, since you hit 180 on both other cylinders, your compression is good, not the best, but good.. Could you turbo it? yup, my friends running 8lbs and a 75 shot ona motor with 172k miles ona stock sohc.. and no, he hasnt rebuilt the motor..

whoever had that motor before you though didnt take very good care of it if it has those compressino numbers and only 30k miles on it..

anything above 180-185 is good, anything 200 n above is a real healthy strong motor

i do find it funny that your first 2 cylinders are that much different then your other 2, are you sure you tested them right?
