Normal compression on a gasoline engine is about 125 psi.
HI, Compression should be 128 to 156 psi, with no more than 14 psi. difference between cylinders.
200 psi
standard compression is 178psi min is 142 psi. +/- 15 psi between cylinders. That's for the 2.2 engine.
87 - 04 compression standard 121 psi minimum 114 psi max 128 psi
then youre running about 8.5:1 compression
29 psi
With the engine off then turning it on, it should be between 23 to 31 psi. With the engine running, it should be 13 to 20 psi.

"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
Engine compression psi? Radiator cap psi? Engine oil pressure psi? Tire pressure psi? Fuel pressure psi?
With a compression gauge.
