    dont know exactly where #1 #2 #3 #4 cyls are so i'll draw it out

    drivers side front, 175 psi
    drivers side rear, 172 psi
    passenger front, 175 psi
    passenger rear, 173 psi

    IMO thats pretty damned good for a near 200K mile turboed n/a 2.2 with no management, stock injectors, and 8-10 psi of boost ( i know a leakdown test would yeild a more accurate test but this works for me) i will be installing my rising rate fuel pressure regulator as soon as i can figure out how to make the fitting that it came with stop leaking. to me it seems way better then the 10% variance between cyls that i was told it should be. what do you think?

    OMFG dude! That's some very deece results. How many times did it have to crank over to get those numbers though? That's still pretty good, but just for fun we should do a leakdown test.

    I agree with Dream. A turbo upgrade is what that engine wants (after the clutch of course). It's begging for it!
