What should the compression in psi be on a jdm h22, is 210 across any good? thanks.

 

That compression ratio sounds about right, anyone want to verify? Secondly, compression ratio is not in units of PSI, compression ratio does NOT have any units of measurement.

 

Its not really the number that is important when doing a compression check. Its how close each cylinders compression is to one another. The actual value will vary by how many times you crank the engine while doing the check. Thats a good number if the rest are the same or very close to that.

 

i would love to explain this to you, but i dont have the time right now. So read this:
