the reason i did a compression test was because of my weak dyno numbers;
139HP
100TQ
w/ JDM 2nd gen B16a I/H/E, ITR manifold, CTR Cams, and FPR

Starting from the distributor to the motor mount;
205, 200, 195, 200

Then added a cap-full of motor oil;
230, 215, 235, 200 <-----not too accurate because the battery kinda give away, but the other 3 cylinders had good cranks

from the numbers above it leads me to believe that my piston rings are fucked, any opinions on what else could cause my motor to be such a bitch????

Around 200 isint that bad I ran 14.6 in my B16 hatch with 190ish in each cylinder..

 

around 200 is the average even for the b18c1

 

okay so at least i meet average compression, but then where did all my power go??? On my original post, i posted why is my B16 so weak and found out that everyone with my exact or near exact mods are making 20-30HP more than me and thats some ****

 

check your ignition. and fuel system

 

i dont think its my fuel because im running a B series pump and i just changed the fuel filter and put in a the bigger SI fuel hose as well, but igition is a whole other story. Should i start with wires then cap and rotor then move into ignitor and coil

 

it could be that ITR manifold.... i hear rumors that a mild b16 wont make any power with it.... it made more power with the stock mani....(clubsi\NA forum guys know more of this)....

i dont know about that one, others were making 160-170HP with the exact same setup and thats where i thought i would be, but when i dynoed it that wasnt the case

 

I think your cool on the comp...look elsewhere

 

could a bent vavle cause such a power loss??? i remember when i first got the motor and ran a chipped P28 that had a rev limit of 8600 RPM, i went vtec happy on that sucker. just a thought because i havent reved it that high since when i just got the motor

 

Try doing a leakdown test....
