Shitty compression #...Need help.
Installed my Inline Pro Headgasket and did a compression test on my car today and got 90,90,90,90 across the board. (Did the test about 6 months ago on stock motor and got 210 across, Car hasn't been driven since) What could cause the extremely low numbers? possible error with the test? It was a cold start, Car hasn't been driven in months, but other than that it started right up and idled fine with the turbo/hondata, no cel's, no smoke, etc....Its driving me crazy. BTW its a jdm 2 gen b16 with Inline pro 3mm headgasket.

Hmm, sounds like an error with the installation of the headgasket possibly, or the timing. have you verified your timing using that headgasket?
Sounds like it went out of timing (not at exactly TDC) due to all the numbers being the same. Unless you torqued all the headbolts at the same lb and isn't torqued enough =X

I agree on timing or headgasket. The numbers are all even, so that's a good sign, but a 90 is not a good sign.

Try to do the compression test on your friend's car with the same gage and see what happen. I think it's your gage.

Im wondering about the timing
Although all teh marks do line up

well if it's a thicker headgasket, you have to adjust your cams by a tooth I believe, this also applies to those who mill their heads to bump up compression.

Most definitely can. One tooth can cause bent valves as well -- but assuming you have stock cams and stock pistons with a 3mm headgasket, I don't believe one tooth will knock valves, but the combustion chambers aren't sealing all the way which means compression is leaking out.
Try advancing the cams by 1 tooth. You need to make sure we have the head at TDC with the bottem end.
