It's a 92 JDM b18c with LSD. It's in a 92 4 dr lx civic

Mugen header
AEM intake
Apexi N1 exhaust
AEM cam gears
AEM fuel rail and regulator
Apexi V-AFC and ITC (only goes to 7200)
MSD ignition and coil
AEM pullies
Mugen clutch
Excedy flywheel

That's all i can think of right now but i probably have more.
MY car only made 143 hp But it made 123 tq which is pretty good but the hp sucks. Please bare with me i know the charts aren't to clear.

This first one is my hp and air/fuel

The second one is my hp and tq

The last one is my hp and tq compared to a stock GSR


Can someone tell me what's going on. I know my air/fuel is not right when i get in the higher rpm's but i was expecting more like 170 hp. I don't think there's anything wrong with the motor because it made a lot of tq. I know the ITC (ignition timing controller) only goes to 7200rpm. Can someone help me

What ECU are you running?

jonas

definately get your air/fuel fixed, mess with the V-AFC and your FPR.

dude, your vtec is way too low.. theres a huge spike there

TruePlayaz114

i think i'm running a p72.

jonas

you said jdm b18c.. b18c as in sir-G/GSR or ITR?

again, your vtec is way too low, do a leakdown test if you can't figure out the problem.

vtecvoodoo

are you running a cat? If so, might want to check that to. I always give the car a tune-up before I dyno. Oil, plugs, valve job, etc etc

TruePlayaz114

it's a JDM b18c as in SIR/G. It's not the ITR. But if the motor had a problem would it have made 123 tq at the wheel. I mean considering it's suppose to make 10 more hp than a USDM GSR and all the parts i have one it i was expecting atleast 170 hp. I think the motor is fine

jonas

more parts does not equate to more power. tuning more parts equates to more power.

dont believe in that 10 whp more than USDM engine bs.. and you think your motor is fine? not according to your dyno.

vtecvoodoo

Just get it running right first. Tune tune tune

TruePlayaz114

but if there was a problem with my motor would it have made that much tq. And i'm running a Apexi n1 catback exhaust

eg6ajk

hope its not a JDM P72. which sucks. yes at least 10whp and 2-10lbs/ft of torque less then the USDM ECU.

also make sure that the butterflies aren't closed at all times, i had that problem on my b18c.

Burke

i dynoed higher numbers than those on a mustang dyno. about 150 whp which on a dynojet translates out to 165 whp or so. compared to type r's with bolt on's dynoed on the same dyno i had an average of 8 more whp and a max of 12 whp more than the type r's. they only got me by like 3-4 peak above 7k.
here is my setup
jdm b18c w/lsd
jdm p72 - stock
aem cai
dc 4-1
no cat
greddy PE
cam gears - +3 intake +0 exhaust
this is also with the timing retarded to 12 degrees so i dont blow it up on the zex. i prolly could have got about 4-5 whp advancing it to 18 degrees.

i dunno. i think my motor is a freak
hth
later

TruePlayaz114

but i just wanna know if there was something wrong with my motor would it have made 123 tq. I mean i look at my graph and it's not bad until i get up top at like 6500

Jackson

Two questions...Are you running your stock fuel pump? You should consider replacing it with a b18c one if you havent already. Secondly, they made b18c's in 92?

BoostedGSRBubble

GET IT TUNED! All those parts do you little good w/o tuning.
Stock fuel pump is fine BTW. I ran a cx fuel pump on my gsr motor and made 168 w/ all bolt ons.

.paul

compression test?

i got my b18c motor the sir/g... it's a 94 no dyno results yet or anything, but it pulls like no other, compression test was 220, 210, 210, 210

all i have is JDM 4-1, and a exhaust, with a straight pipe.

good luck, hope your compression numbers turn out okay

-Paul

thecord

that should be making at least 170.. get a thorough tune up before you dyno.

ajchen

i think there is someting wrong with your motor. doesnt matter that you're making decent torque... it shouldnt be running that weak, mods or not. definitely get it tuned, but before you even do that, do a compression/leakdown test.

good luck..

hybrider

i made 143whp when i was stock

your 2ndarys as mentioned earlier, obviously isnt the problem....

tune

memphiss13

something is definitely wrong. my b16 made 157whp with just intake and exhaust

J2turbo21

Yea I think stock gsr's make around 150whp so you should be good for about 170whp.

BlackNoise

tune that **** man....my friends b16 made 137...your power curve looks crazy go nuts ugly. good luck.

RangerDan

You get that thing tuned and it should do more that 170. Which motor used the p73?

TruePlayaz114

i'm gonna do a compression test today but what is exactly is a leakdown test. What is included in a leak down test. What do you guys think of my curve before i hit like 6500. I mean it looks like a nice straight curve until i get uptop

JDM_Sol

leak test and tune....should solve your problem.............
