i just put on my V-AFC to do the vafc hack for my turbo LS in my crx.......i tried to install my DSM 450cc injectors i got but they were too fat to fit in the injector seals?? is this common how do i fix this??

and heres a pic of the injectors.....are they the right injectors???? thanks!

You need to bore out the stock seals...or order bigger ones from http://www.allorings.com

i mustve been eating my wheaties, cuz i got those things to fit in w/ some wigglin.

KoRE

they fit fine in mine i just gave them a shove but i'm on a d16.....
i bought b16 injector seals and didn't even use them

CovertFI

so they fit fine with d16 injector seals? good info

boostinb18

yah i think i will just shove them in and then tighten down the fuel rail!! thanks for the help guys!

if you want to get them cleaned and balanced..send them to http://www.cruzinperformance.com

$10 an injector..you cant go wrong.

tonydatyga

damn straight, and I would just dremel a bit off to make them fit willingly... unless you enjoy fitting fat things in obviously undersized openings. Holy crap that was so wrong

Mine were a tight squeeze also. I got some injector o-rings from Napa. They are about twice as thick as the stockers, and are made of a better material.

What I did: I bored out the o-rings slightly, removing the inner lip. Put a dab of oil on the top of the injectors. Popped them into the fuel rail. Put the o-rings in the manifold. Alligned and seated the fuel rail with the injectors sitting in the o-rings. I then proceeded to install the three 6mm bolts on the rail and tighten each one, slightly, and moving from one nut to another. The injectors seated nicely and are not leaking

I've bored out a ton of stock grommets with a rotary rasp.
Just FYI, -ALL- honda injector grommets are the same. D16, B16, etc. All the same.
If you are gonna try forcing them in, you might want to try popping them in the microwave for a bit to soften them up (dont try this with females living in the house. They dont seem to like the idea of car parts in the microwave).
Its really not that hard to bore them out, if you have the right tool that is.

yeah, I totally had to bore mine out...I don't think there's anyway it would've fit without risking tearing the ring...I'm still running the 450's with no management and their fine, just a hair rich, according to my voltage meter on the o2 sensor.

I just put the injectors into my rail, and then lined up the bottoms with the manifold and bolted the rail down. It was a tight squeeze, but they went in without any boring of the seals.

yah i just shoved them in and tightened the rail on!! it seems to work fine but the car does feel faster! but the idle is ruff......my settings are -40% 1000-5000 rpms then -35% from 5000-7000 rpms......does this sound good?? and should i leave my check valves in??? my FMU??? my inline pump????
thanks!

you can ditch the check valves, FMU, and inline. You can get an intank down the line, but a lot of people are running on their stock pumps without any problems.

Not to create an argument, but that isn't entirely true. I have at least 3 different sizes at home. Some thinner (top-bottom) than others and some with larger bores. I've been through so many engines (not just mine), I forget what they came off of. I must have about 30 sets of injectors in my basement

One thing noone has said, but is very important, is that you should oil the hell out of the seals. A good coating of 10W30 will make them slip right in. I did dremel out my seals to amke it easier, but the oil helped immensely.

I put all the seals in the manifold first, then pushed each injector down over each one. Then bolted on the rail, no problems.

yeah DSF is right the d16 is thinner then the b16 and i didn't check the bore sizes but i guess i should have i'll see if i can borrown my friends digital camera and post some pics......

rioninja

Good to know
to rephrase that, all the injector grommets I'VE ever seen have been the same. I've dealt mostly with JDM B16s and older d-series.

SlowB16

Could someone post a pic of how much they had to bore the 450's?

GOLDBERG

good info..so will the oil affect anything negatively???just slip some onto the injector??or onto the seal?
