i have a j-1992 civic lsi,with a d15b2 engine in it,which i belive has 92bhp?
i want to tune it to around 120-130ish and i was wondering which route to take.i was thinking about just getting exhaust,manifold,induction kit and maybe some ecu work of some kind,,can anyone tell me what hp increase i might expect to get,,or if u think i would be better swapping the engine??

any help appreciated

mpfi swap would be a good idea.

look at my sig and the 1/4 mile run.
That 15.6 run is when i still had the wrong a6 timing gear on and my valve timing was retarded, now I have the y8 timing gear and i have my low end, mid range, and top end power back. Probably now it would run 15.4 or so.

Just a d15b2 with a stock dx tranny and stock clutch, all have 220 000km including engine.
ONly mods are 2 1/4'' exhaust, ractive 4-2-1 header, free flowing muffler, 3'' short ram intake and cone filter.
but the most important mod is MPFI SWAP SO DO IT...all my parts for the mpfi swap were from a d16a6. So im using the pm6(a6) ecu, injectors, intake manifold, a6 cam, throttle body(which i polished by the way).

My write up I did a little while back, i wrote it late at night so its formatted so it seems like theres too much info, but everything you need to know is there, feel free to ask me if you have any questions.

thx,for the info dude!sounds good,,some1 else recomended i use the entire a6 head with the z6 intake manifold and multipoint and a ecu off a dx!what do you think about that??i just trying to gather as much info as poss at the moment..

the intake defintely, the head will give you more options with camshafts.

well if u dont want to do the mpfi swap which you should, then get the a6 cam or head(supposedly b2 and a6 heads are the same except for the cams)...you could take the dpfi cover off and take out the little restrictor screen on the throttle body and the other plastic junk on the inside.
But if you do go mpfi, definately go for a z6 intake manifold( but be sure to use a6 obd0 injectors with the a6 pm6 obd0 ecu)...also the z6 throttle body would be a good piece to have along with the z6 intake as even though the air intake sensor and MAP sensor wires have to be extended a little bit and even though the z6 tps and all other sensors are off a obd1 car, everything will still work properly with the a6 pm6 obd0 ecu

hold on though.....your cars a 92???? then i think you have a d15b7 which is already obd-1 and already mpfi'd......but im guessing its neither an american nor canadian car...so who knows..lol....for example uk models of new jeeps have turbo diesels...who woulda thought :)

its definately a d15b2,i checked the engine number,,i think i have a wierd model,,the car is an eg civic with j registration,j is 1991 but the car was first regestered in 1992,,maybe i have a 1991 engine in a 1992 shell,,,its not been swapped,i dont think.when i got it it had 1 previous owner from new and it had 45thousand miles on the clock

mpfi swap is well worth it. you can also do a mini me swap (non vtec block with a vtec head.

10-06-2006, 12:04 PM
since your car is 91 0bd0 use pm6 ecu on the mpfi swap

same engine as mine, D15b2 dual point 90hp
all 1.5 civic hb 92-95 in europe have dis engine.

really eh...hmm my thoughts were correct about the wacky differences between US/CANADIAN, UK, and European honda models.
But ok so d15b2, so you need to convert to mpfi, so basically go according to my instructions at first.

could you tell me which gearbox i have in mine?,,its a lsi if that makes a difference

sure....at 100km/h(60mph) in 5th gear...are you reving at 3100 or less(dx 5 speed tranny) or 3750rpm or more(si) tranny

ok,mine revs at 2900rpm so i guess its a dx

man....my 90 dx (d15b2)wouldn't go to 90mph,,,,it took forever to get up there....
d15b2 blew.....
swapped to a crappy d15b8,
stock with dpfi ran a 20.5
I/H/E ran a 19.3
b7 head swap..milled ran a 18.3
mpfi swap ran a 15.9

mpfi swap practicly made a 2 1/5 sec. gain

MPFI SWAP IF YOU HAVE DPFI FTW!!!

ok,ive decided to go for,,a6 cam,a8 timing gear,mpfi swap using z6 im and tb,
all other bits for mpfi i will take from a doner car i intend to buy,one fitted with a d16a6 mpfi,i think thats right..all thats going on my b15b2 btw.

i will also be fitting an induction kit,4-2-1exhaust manifold and a stainless cat-back,,,possably a few other things.

let me know if you think my plan is flawed at all......

my civic is stock and its done 120mph and i recon it would do a lil bit more too

do induction kits fit dpfi and mpfi the same,,so if i buy an induction kit now and upgrade to mpfi later,my induction kit will still fit???

Nope, compleatly different in almost every way. Do the MPFI swap first, then go F/I.

if by f/i u mean forced induction ie turbos,superchargers,i never said anything about that!,,by"induction kit" i meant an airfilter upgrade

Dweezil
10-06-2006, 09:43 PM
Sorry, I assumed you ment forced induction when you said induction kit. The DPFI and MPFI are slightly different, the DPFI is set slightly lower and is further from the airbox, but not by much.

malone83
10-06-2006, 09:47 PM
ok,cool,,so i could probably get away with it then

Dweezil
10-06-2006, 09:50 PM
Yeah you could probebly get away with it, but your not going to gain much if anything. I'd save the money for the MPFI swap first, then worry about an intake. Or get a stock DA Integra arm and use that.

so,does all that sound ok??will all the a6 injectors and other bits and bobs fit the z6 im and tb??

MPFI SWAP IF YOU HAVE DPFI FTW!!!
HAHA..i hear you man, MPFI SWAP DOES A BIG DIFFERENCE . You shoulda seen the big argument I had with this one guy on honda-tech, he said he wired up "over 1000" mpfi swaps and none ever made any real difference from dpfi, ok der.
I said it once and ill say it again, MPFI swap from dpfi is the only 10HONDAwhp+ that actually makes a night and day difference and in most cases a drop of 2-4 seconds off the 1/4 mile.
Even if you turbo'd a dpfi going 19.3 1.4 mile, or 50 shot of nitrous, something tells me it would still be a weak 16.9@XX.XX run...mpfi is the way to go babeez.

And for Malone83: everything you stated will be good. I think you meant y8 timing gear instead of a8 as i have the y8 timing gear and it solved my d15b2/a6 cam timing error. And the z6 intake manifold and throttle body will work great on the d15b2, and i think if anything, you may just have to use the little rubber injector plug things from the a6, but the z6 ones might fit, either way if it turns out to be a problem, 1.5 seconds later you have a solution.
Good luck on the swap, and use shielded wire pleeeze.:TU:

yea,i meant y8 timing gear,sorry..
thx for all the info people,,any more tips or things i might of missed would be appreciated,,thx all

you can also tell if its dpfi if it as that little black circle thingy in the intake manifold. converting to a mpfi is definately a good choice. Why have 2 fuel infectors when u could have 4? i have the same motor but instead of spending up to 400 bux on the entire mpfi system i just decided to buy a rebuilt d16z6 which already has mpfi as well as the vtec for the extra umph for also 400 bux. and it makes about 125 hp which is what i think u were looking for but if you did the swap then u should still get at least an inake.

got a 91DX Sedan
D15B2
Totally Cherry Red&Black
I am seeking horsepower...
I want to do a mini-me....

I have replaced the plugs : Bosch Plat 4's
I have replaced the wires : Bosch again
I have replaced the valve cover gasket and the oil pan gasket
It was not leaking oil, I just had to see the top and bottom.
Whoever had it took care of it, inside and out.

I modified the intake(disengaged the snorkel)
saving for exhaust.

It will look stock;) It will sound stock at idle;) but it will not feel stock on either side of the gas pedal.....ever
