Just tested my s2 rb25, it was cold and dry but I thought of that after it was done. I read 140-150 is good but I also read people driving 400+whp with 120psi and nkt having problems for years, obviously situational. My results are as follows cyl 1:120 cyl2:110 cyl3:120 cyl4:115 cyl5:115 cyl6:115


Just wana know if it that is acceptable

Seems low, I assume you are running this motor already by the cold and dry comment?

does it have stock cams?

If its not filling the catch can i wouldnt worry..

mac, aren't they pretty well within ea. other - not a bad "grouping".As long as you don't feel the subtle "bumping " of a bad cylinder upon brisk acceleration your OK ? Now people will tell you to squirt Oil in each sparkplug hole and then you WILL see a rise - Now you've just fouled all your plugs . Be smart and keep the OLD set of plugs to do that But your probably OK that w/oil you gonna come up 10-15 lbs!
From a cold sitting motor - everything sort of is very normal. G 4/5/2018
