I did my compression today on my b16a. Every thing is stock. I got 215 in every cylinder. Is that good, and what would my ratio be. thanks guys.

 

as long as they are close you ar ok

 

I know but is that high or low compared to everyone else

 

i got anywhere from 170-185...

 

Thanks, has anyone else compression tested their b16.

 

i think the manual says 175-185...dont quote me on that. give or take 15 per cylinder. i would not worry about it. ****. u have high compression. worry if it is low. but thats just my 2 cents...

 

if everything is stock then ur comp ratio is 10.2:1

 

If stock is between 175-185 then why is mine so high. I know that it is good to have high compression but what would have caused mine to be so high. dose it matter if it is jdm or not. mine is.

 

what is the formula to convert psi to ratios?

 

i dont think there is one... i thought you calulated ratios based on bore/stroke, piston height and combustion chamber volume.

 

i did one on my friends old b16 when he had a bad headgasket and it was at around 213 and one was at like 156 then wwent back up..... and my sohc vtec is at around 195 so 215 sounds fine..

 

I got 210 on three of mine and 170 on one. So 215 across the board is really good

 

anybody know how to do a leakdown test and where I can get a leakdown tester at. I've got a compressor, all I really need is an attachment to go from my compressor hose to the spark plug hole. Any ideas?

Will I need to take off my intake manifold, exhaust manifold, and oil pan to hear the air coming out.

Also, my compressor maxes out at about 125 should I just take this to a shop.
