.....I did a jdm b16 swap into an eg DX hatchback. get everything timed right, motor is running good and everything, but it just doesnt pull like it should. vtec opens up real loud, but nothing pulls hard. we did everything needed for the start-up warranty from hmotors (car, rotor, plugs/wires, tbelt, h2o pump, etc) along with draining the gas and putting 92 octane in there along with a new SI fuel pump (because we dont know how long it had been sitting). i throw no codes now that the knock sensor is in, and it still doesnt pull. it has everyone i talk to stumped. please help me honda gurus!

 

you can't expect a stock b16 to pull THAT hard man,
if your car is faster than it was before then thats a plus

 

Maybe you're expecting too much torque out of a 1.6 liter.

 

go and get the car DYNOED

 

no, i lost to a stock v6 camaro that i used to beat in my stock 92 h23 prelude, and i ran a guy that has the same exact swap that im friends with and got waxed! even from a roll! they even drove it and said that it doesnt pull at all.

 

i would rather not spend the cash to get it dynoed when its not even running right

 

and you're sure that VTEC is engaging? what ECU are you using?

 

should be the p30 that came with the complete swap from hmotors. and it gets really really loud at a decent midrange rpm (not sure, havent gotten the tach yet) but nothing happens.

 

bizump

 

Do a compression or leak down test. And let us know what the numbers are. Are you still running stock parts? Like intake, exhaust, exhaust manifold. Maybe some aftermarket upgrades. If I was still in Nebraska I would help you out.

 

is the knock sensor wired up correctly?

 

i think u're just expecting way too much out of a stock b16, maybe do some bolt ons, CAI, header, exhaust ect. then u'll feel a difference.

 

maybe he needs a new clutch?

v6 camaro?? get that motor checked out ..... a freind of mine told me he put a jdm b16 in an ex, and he said my b16a2 runs better, im in a dx civic though ,but im pretty sure theres some nice jdm swaps out there....but your in a hatch it should be pretty quick

 

dude b16 has no torque what do you expect?????? and also are you a good driver it doesnt matter what kinda motor you have in your car if you cant drive you will be owned!!!!!!!!

that'd make me double check the timing again, then the compression check ordeal

My worned out clutch on my Z6 makes it pull like a *****. Is your clutch like this?

That could actually lead you to the problem, maybe it's missing up top, you'll see that on the dyno chart. The $100 is well worth it imo.
Also if your making the rite power for the motor (within spec) then you know nothing wrong....you may just be expecting to much out of it....

 

Are you still using the stock dx exhaust if so there's your problem.

 

Yes your expecting too much, just like me...I expect my sohc to pull as hard as a b16...well it does on 1st gear :] but all the other gears...just feel like a sohc :[ Still im happy with my car bwahah!

 

It's bitch when reality kicks in, huh?

 

yeah i am, it must be too restrictive......would that be why im gettin NOTHING whatsoever? thats what ive heard from a few people.

 

Yup thats the problem the stock dx exhaust can't flow enough at high rpm for your motor. Plain and simple

I run the stock dx exhaust on my b16a2... I think thats far from the problem, try a compression test or just go to a dyno , you just gotta suck it up and do it , its not going to get done just sitting there

 

remove the exhaust and take it for a quick rip. thatll answer your questions.
