Finished MINIME but low compression?? HELP
Ok guys, I just finished doing my MINIME swap 2 days ago and I spent all yesterday trying to figure out why I have very low compression. I have pretty much 90 across the board. Shouldn't it be at like 140 or something? Also I used a NON VTEC headgasket and I had to cut the farthest 2 top holes to make it fit but I instagasketed those... do you think this is why? Should I just go get a Z6 headgasket? I really need to get these numbers up because I am planning on HMTing this within the next week (already have everything). Any ideas?
Thanks
Thanks

OK guys, I just went out and redid another compression test with a wideopen throttle, and my numbers changed. Its like from cyl 1 to 4 the compression gets better.
1 = 40
2 = 50
3 = 70
4 = 110
Any ideas what this could be? Im REALLY leaning towards the headgasket now...
Also does anyone have an answer for me about the B7 distrubitor on the Z6 head?
Oh and I have tried 2 different compression testers...

Re: Finished MINIME but low compression?? HELP
you need to pull the ECU fuse to cut fuel and spark as said earlier
crank at WOT untill the gauge stops jumping and stays steady
all your tests seem really low.. did you make sure the block and head were flat when you used them? my Z6 had 198 across the board before it blew if thats any indication on what you should be getting
