just did a compression test on my B18.....what should it be???
what should the compression be on a 90 B18A1?!?!?!?
i just did a compression test and i got ~150psi across??? |
Re:just did a compression test on my B18.....what should it be???
i thought around 190-220

Re:just did a compression test on my B18.....what should it be???
yeah....me too... :-\

Re:just did a compression test on my B18.....what should it be???
come to think about it...my ZC had 150compression, and my D15 has 150....maybe my tester is just gay??

possiblity too....but i have had my WB sence i went to the dyno, only times i have been lean were at cruzing speeds not under load...

Re:just did a compression test on my B18.....what should it be???
Your rings are just fine, that is the correct compression for an LS due to it having a 9.2:1(i believe) compression ratio.
My b16a had 170-190 across, but that was because b16's have 10.2:1 compression. My LS Vtec motor has 8.5:1 and when I do a compression check it gets 120psi across all 4 cylinders. |
Re:just did a compression test on my B18.....what should it be???
umm....i thought that the place that sold me the motor said something about 200-205 on all cylinders?
i was thinking the same thing about hte CR...the ZC/D15/LS all have about the same CR...so same on the compression test then! |
Re:just did a compression test on my B18.....what should it be???
when i rebuilt mine the compression was about 175 acrossed

Re:just did a compression test on my B18.....what should it be???
130 or 135 is de minimum...you're still ok
|

I assume your opening up the throttle when your doing the compression test?
