Simple Q,
I have searched,
most people say all b/d are 240cc,
but that is obviously not true, there are various smaller cc injectors.

now I have a d15b vtec and the injectors could be causing me electrical problems.
Will the injectors of my 92 cx motor be the same??

is there a way to check?
I've got the cx's right here.

ABK

well I've used dx injectors on tha swaps before. As far as I know d, and b series use the same injectors.

Part numbers are different though between z6 and b8 injectors

I would try to use them, but if you feel your engine starts running messed up replace them.

ARIZONA

Same.

Tad

yeah only thing is the cx is really extreme as far as a lowpower output motor goes.

I mean if you look at the TB compared to the d15b TB,
the cx is like half the size!

anyone kno fo sho?

i'll probly try em out to troubleshoot my elec. prob,
but I would like to know for the longrun.

thanks.

(Ive heard the 96+ CX units are smaller cc/min but I dont believe it.)

Damn you would think they would be considerably smaller because the car isnt getting much air (intake mani is smaller than the carb on my dirtbike!!! lol)

But I guess I learn something new everyday

Tad

well i'm looking at both right now
they do look different but similar.

visually identical except,
heres the differences.

d15bvtec:
green nipples
have 5IH3 written on the side

d15b8:
orange nipples
have 1FLC written on the side

aside from that they look the same

wrong and wrong i had cx injectors in my d15b and they ran the car so lean it was throwing 02 sensor codes. do not use cx injectors !!!!!! they will **** up your ****

ABK

cool, btw the link up there is great, should be put in a FAQ or something. Very usefull stuff.

Tad

faawwkk

ok .... wtb 235cc injectors!!!

thanks guys

Harry_Randal

Ah hah! lol

Good thing you found out before using them badboys... or shall I say them lil boys

Thank god for H-T

Tad

heh, i'm running them right now, haha.

needed to diagnose.
looks like the buzzing i'm hearing isnt coming from the injectors..
might be something right below them, like the wiring or maybe oil press sender ...

so i guess i dont need new injectors afterall

take them out or stop driving the car. using them may cause you to burn a valve. BTW those injectors are holding you back by 5-6 tenths

yeah i know man,
I just put em in to diagnose my electrical prob,
drove around for a while and took it real easy.
car felt alittle sluggish but no problems.

put the d15b injectors back in already.

oh and I broke one of the bolts/studs the the fuel rail mounts to

YAY!!

oh and by the way,
**** this **** i quit

its one thing to use cx injectors with the correct fuel pressure regulator and fuel pump (for the motor) but its another thing to use a CX pressure regulator and CX injectors and a CX fuel pump for a bigger/vtec/dohc motor

Tad

well i tried my cx injectors on my d15b,
with the d15b fuel system, only the cx injectors swapped in(from a 92 cx)

it ran ok, was felt alittle sluggish at lower rpms,
I didnt try to take it into higher rpms.

but definetely wasnt anything gnarly or life threatening for my motor.

bump for some more opinions.... i have them (92 cx injectors) installed right now on a SirII b16a swap and need to know the size of the injectors. I have 240's on the way but was wondering if it is safe to drive approximately 5 miles on these injectors in order to get the new ones put in.

dude someone already replied with a site that shows the cc's
its 180cc for the 92 cx injectors.

pretty low,
but its definetely safe to drive 5 freakin miles man,
just dont go mashin on your engine hella hard,

only time i'd be worried is if I was boosted.

you know you could put them in urself also
it isn't hard at all.

just be carefull tightening the fuel rail bolts.. i snapped mine off

y0 homie hows the sohc treatin' ya? dont know the whole story... but where are they d15b injectors? didn't matt give you the whole manifold to use? anyway... let me know if you need anything... just not this weekend cause my motor is goin in

edit... ok dammit nevermind... you're having electrical problems... i have a shetload of extra sensors if you wanna try anything out... lmk

BatuKing

Are you getting code 16? also what is the Resistance on the injectors your having problems with&gt;?

thanx man, the setup is going pretty well now.
fixed my electrical problem, turned out to be a loose transmission wire..
looked like it was on there.. but then i jiggled it and noticed it wasnt torqued down.

I thought it could have been the injectors cuz they got pretty oil soaked(maybe shorting) so thats why i was trying the cx ones.
Matt definetely gave me the whole shabang though, I have the d15b injectors back in there now and they work fine.

still gotta get an exhaust though, mines busted and sooooooooo loud

dude wtf are you talking about both engines are sohc and i was using a d15b fuel system with 93 cx injectors. the car ran so lean it threw oxygen sensor codes. i talk from experience. maybe you should to

morningstar

hmmm no wonder when i swapped in the d15b with the cx injectors all it did was smoke and give me an erratic idle...pos
