I did a compression test and got 230psi across the board. Its a b18c1 motor wuth 70k on it.

I see in helms it says 270psi is nominal.

What are you guys with b18c1 motors getting?

225 across cept cylinder 4....did 195...

 

230's across the board is great... do a search, most of the guys are coming in between 210 and 225 or so.

230 is good compared to most i've seen, but if 230 is so good why does the Helm manual say 270 is normal.
just a ?

 

Its all dependant upon the tester you use -- Im sure its not identical to the tester Honda uses. 230 is awesome

 

Not only are you looking for higher numbers, but you're also hoping that the cylinders share close to or similar readings.

230 is damn good. My compression results for my '98 GSR with 118,xxx miles was (from Cylinder #1-#4) 205, 195, 190, 205. They're lower than yours but still within the normal specs.

 

I just did my sisters GSR with 80k. Her's were 240 except the 3rd clyinder was 230.
