hi guys !! i have a 99 honda civic hatch (cx) i have a b16a2 engine in it with a gsr tranny and i went to the dyno today n came home crushed It only had 115 hp they told me that i should have about a 150 with my mods any advice questions please ...

tommyka

why or what shoul i do or thats normal? ( i don 't thin so)

azandford

first off a b16a2 should be putting down 140-145 to the wheels bone stock

what mods have been done?

how many miles on the motor? have you done a compression check?

is vtec engaging? any cel?

need a bit more info before we can help you

tommyka

ok
i have a dc header,exhaust system, intake system, and i have a p 28 ecu i dont know too much about this stuff but i know i have these i also have fuel presure regulator and an msd 6 box. the engine has about a 100.000 km;s and no i haven't done a compression check . The v tec is engaging at around 5000 rpm . what;s cel? sorry thanx in advance!!

Welcome to the world of gutless b16's.
Throw the msd in the trash it isnt doing anything, Was the car tuned or just dynoed?

tommyka

it was just dynoed and the check engin light is not on.

Try doing a full tune up for starters. Also do a compression test. Does the motor seem to run well other than the strange lack of power?

tommyka

yes the engine runs excellent!

tommyka

i made an appointment to a tuner for next week w'll see what he says. the wors case i gotta do a swap.
no money for that now

tommyka

my goal was to get about a 150 hp thats why i got the b16a2. im confused

98civdx

Do a commprerssion check

my friends made 142 with im,header,intake, ciped and tuned p28. he has perfect compression across the board.

tommyka

i just did a commprerssion check today ,an they told me it;s perfect 190 all the way!!

then what else could cause the lack of power??? any guesses?

gsrhatch2356

lots of things cause loss of power but you should start with compression, mechanical timing, then a\f ratio will give you a good idea of where to start to find your loss

98civdx

my friends was 220-225.

What type of dyno was it on? some dynos read differently then others.

gsrhatch2356

140 is averge for a stock setup and intake and exhaust dont yeild that much

98civdx

Average? i would be worried if my b16 went that low, the lowest you ever want to see them is around 130psi, your in bad ring territory on that one.
My other frineds with over 200k still sits right around 180-90

D16SiHatch

i believe he meant 140hp, not compression psi.

since we're on the subject though. 135psi is the minimum, and 184 is nominal, with a max acceptable variation between cylinders of 28psi.

gsrhatch2356

yea 140 wheel hp at that. of course its 160-170 at the crank usally if the compression is good you should see around 180-200 on b16 or b18c and we put some type r's in with new rings and we got 230 out of that of course they are 11.1:1 but these are just realitive. just start there and see what you come up with
