compression numbers doesnt really tell you anything except for how your motor is sealing...atleast in my experience


Here's an example of how my motor's compression was:

H22 NA 11.8:1 = pinned the compression tester at over 325psi per cylinder
H22 10:1 stock USDM= 150 per cylinder
H22 10:1 rebuilt 4 years ago..=160 per cylinder
H22 10:1 stock JDM = 220 per cylinder
H22 10:1 built = 260-275 per cylinder
GSR turbo 9.7:1 = 250psi per cylinder
