Well did a compression test and this time did it the "right" way.. Unplugged injector clips (removing fuel pump fuse or ecu backup probably work just as good). Took all 4 plugs out and did it when the car was WARM, hot even. Also WOT everytime during cranking.

Cyl #1 195psi
Cyl #2 185psi
Cyl #3 185psi
Cyl #4 190psi

These are much better then my semi-warm non WOT readings of 175psi avg.... I think my motor is handling boost pretty well so far and am proud of her

 

how come my JDM B18C with higher compression got the same # like urs

 

Did you do it the same way I did? REALLY warm motor, full throttle while cranking, and disconnected fuel in some way? Its more important that the numbers are consitant like 20% difference MAX. some gauges are off, some aren't.

 

my friend and i both got first gen b16 motors and his read 180 across while mine had 215 across. Same compression tester so i don't know what was going on

 

Sounds like wear.... how many miles? Only problem is it could be a whole crapload of different things, headgasket on its way out, ring or piston wear, head... all kinds of stuff, only a leakdown would give you any grounds of the problem..

but honestly I don't think its a problem at all and wouldn't worry about it unless other symptons came along.

 

nah i did it after i drove the car like uhmm an hour approx
i didnt disc the fuel lines , but i did it @ WOT

looks like my pistons rings are fucked

 

Nice numbers...
I did a compression test yesterday and i got:
1: 190
2: 185
3: 185
4: 190

I have 114,000 miles on my engine (B18B), 54,000 of it with my turbo (Drag 3) boosting 7-10 psi.

 

forgot to add...my car is a 1995 Integra.

 

Nice!!! just more proof that the good ol b18b's can take it :D
