i have a b16 swap in my 90 hatch...i have a 95 gsr port and polished head on a b16 block with 81.5 pr3 pistons. bottom end has been redone at the machine shop. well i did a compression check and im at 180 psi on all 4 cylinders. well not all at 180 but like 182, 181, 180, 183 . my buddys 00 si is around 220 across all 4 cylinders so im confused. i am bogging a bit so thats why im concerned. i know theres no real def "good" comp since i have a gsr head and its hard to say whats good or not. just dunno what my next move should be

 

I know a gsr head will take the compression down if its on a b16 as compared to the b16 head. My buddy did a compression check on his si b16 and it was 210 all across....I have a Jdm B16a in my EK hatch with low miles...about 75,000. I ran a compression check on it and it was 195 across all. i looked up in the manual and on the net and a b16 is supposed to be around 195. but with the gsr head on it it would take the compression down for sure

 

I think B series motors whenever you do a compression check, should be between 180-220 psi. The D-series, should be between 150-190. On my D16y8, the compression was between 180-190.

 

so am i lookin good? i know if i had a big diff in psi's id have a problem but it was all even..hmm i still have a bogging issue
