Hey I don't know if this is in the right forum so sorry if it's not. I just did a compression test on my b16a first gen. motor and I got 180 across the board. I heard that stock #'s on USDM b16a2 is 190. I just need to know if these numbers are ok since my local auto store didn't have a manual available. This motor will be turboed down the road so that's why I need to know if these #'s are in spec. Thanks

 

yes thats fine

 

thanks guys

 

nah man thats too low u should get 300psi hahahahahahahaha LOL....
180 is kool....thats where its suppose to be anyways

 

as long as your compression in all cyl was within 5 points of eachother.. 181, 183, 180, 184 etc... your ok... if they were all at exactly 180, maybe you testd wrong or your motor is perfect

 

2 cylinders were 180 and the other 2 were like 2-3 psi difference hard to tell exactly what number since my gauge didn't have slash marks between 175 and 180. And from what C-speedracing.com states that you can be +/- 20 psi apart before you should start to worry.
