Fuel Injectors

[od2681]

Ok i know that right now my injectors are screwed up and everythin cuzz fuels overflowin and there is other stuff....anyways, I went to auto zone and they told me that it will cost 365 for 4 injectors.......365!!!!!!!!.
Im going to try to get some for 80 bucks at a junkyard....i will take a mechanic with me to check them out...
anyways how much did it cost you all for injectors and will those injectors be reliable...i mean the junkyard ones if they are in good condition..the guy said that they were usable

try nopionline.com
also check rc engineering, dunno how much they charge though.
$80 for junkyard injectors? You must be kidding. If you get from the yard, just make sure there are no stains on the manifold.

I got factory injectors from RC Engineering (rceng.com) for $42 each. You will have to get the number from their web site and call as they are not listed on the site.

are you sure the whole injector is shot? the o-rings may have just worn out because when they go bad you get fuel everywhere. see if spending $40 on the o-ring set fixes it.

[DBMaster]

I am betting against o-ring leaks. Since the new injectors come with o-rings all you will end up doing is wasting money and time and just have to take everything apart all over again.

I had three leaky injectors; o-rings would have just been a waste of money for me.

Does anyone know if the stock B16 injectors are peak and hold?

[Kevin]

Peak and hold?? Whats that?? I know that other honda injectors will work good!! I have a set of stock H22 injectors in my hatch!! But i also have a few bolt ons!! The stock injectors are 235cc and the h22s are 310cc!!! I think the Gsr and Si injectors are 260cc!!!

[AZmike]

!!!wow!!!?? Thats amazing!!

If I'm not wrong, all Honda injectors are peak and hold. But you can't just dump another injector in there and expect it to run correctly. Your ecm needs to be corrected.

[AZmike]

If all four injectors match, can't the ECM use the oxygen sensor's signal to figure out that it needs to shorten the time the injector is open?

[AccordEpicenter]

most honda injectors are the same 220cc i believe, so in theory you should be able to grab some, say from an F22 for example and theyd work no prob, but ive never tried it. I heard somwhere that b16 injectors arent peak and hold... but im not absolutely sure.

The stock ecm is not calibrated for it. If you use bigger injectors, the stock injector pulse width that should work now wouldn't. You'll have an imbalance fuel mixture somemore in the power band. I'm not saying it won't run, but it might not run correctly. With the correct fuel map, it'll run better. True, the ecm might change the values due to the o2 sensor readings, but what happens when the car runs in open-loop at WOT.

[AccordEpicenter]

the car will physically run but with the stock fuel pressure regulator pushing the stock pressure itll run way rich. If you have an adjustable one you could try lowering the pressure a few psi but im not sure how thats gonna affect your mixture quality.

Ok, I have no clue what you guys are talking about with with hold Bs-Ill i know is my accord hatch had 235cc injectors and know there are running with 310cc injectors from a 94 h22!!! The car does run better-probaly mostly Bc my seals were leaking-but it DOES NOT run rich!! The tip of the muffler is still clean a week after cleaning and the A/F gauge reads stoich @ regular throttle and @ WOT it reads rich!!!
