Are the Accel fuel injectors any good? The Holley's are $475 and I can"t afford that right now.I don't want to put my manifold and everything back on with the original injectors, but I've already spent a lot of money. I was going to send them to cruizin performance but he said my injectors were some of the worst ones ever made and would not be worth servicing.

i have them and i love them. They are very good priced and if you don't like accel, you can always get ford SVO's injectors. Please keep in mind that the SVO injectors are rated at a lower fuel pressure.

I have acctually heard the opposite! Not starting a "flame war" or anything but i had to change injectorts b/c of this. I am waiting on my new injectors as we seak. I had the Accels and when i went to order my prom from fastchip.com/ Ed Wright, i was told that i should go with the Ford SVO injectors. When i had asked why, they said that the Accels are never the right rating as they are advertised. They said that they are almost always off and that the Ford's are more consistant. I was told that they were always taking chips back and having to re-tune them and send them back out. It was such a pain and the chips never came out good enough that they do not burn any more chips for cars running Accel injectors. Just a word of advise if you are going to have fastchip do a chip for you, do not get the Accel injectors. They will not do it. Now i am waitng for these Ford injectors to come in so i could possibly get my car running. Good luck

I guess i must be lucky two times, i installed a set of accels in my friends car too and they work so far so good. So i can't say anything negative about them. I have heard many postive remarks about the SVO injectors so if you want to get those, those are fine.

86IROCNJ

Yeah, i am just changing injectors due to the fact that i had to since fastchip does not deal with those type of injectors. I have never heard of this problem before otherwise i would not have bought them. The only difference between the two is basically the price and this "problem" i guess. The SVO's are around $219 and the Accels are around $229. Both, from what i understand have a spray pattern just like the Bosh design. If you want, you could always go with the Bosh injectors. They run about $500 for our application. I doubt that they would be "off" either. good luck

Are the SVO injectors the ones in the Mustang section of the Jegs catalog? derfrank, you said they are rated at a lower pressure, I'm installing an AFPR and plan on running around 50psi. will they be okay for this? Anyone else with any info or opinions please post, I really need to get some injectors ordered, thanks!

1990GTA

I just did a search, so if I want to stay at 22# , I need to order 19# SVO?

91RS5speed

Im running the accels in mine without any problems had them for almost a year now. If you have a 5.7 I say just go with the 22 pound.

86IROCNJ

The part number you want is 397-M-9593-A302, which is out of Jegs. Where ever you order it from, the model number should end with M-9593-A302, thats for the 24lb/hr. Really not sure about the injectors being "off". Like i said, i just had to switch b/c fastchip had problems tuning chips for people with the Accels, that is the only reason i switched. Now, if they wanted me to go with the SVOs, i would think that they have had better success working with those injectors, IMO. It was a hassle to take out the Accels and order new ones but i had to do it otherwise i would not be able to have a chip from fastchip. I am sure tons of people have had good experience with all types of injectors. Just buy what you think is right! Thats all. If you plan on going with fastchip down the road, don't get the Accels, that is the only reason i have posted. good luck

i never had to change injectors yet, but i most likely would go with accels.

What kind of power are you making in your car, is it bone stock?

1990GTA

350, Crane Powermax Cam 270/276 adv.dur. .452"/465"gross lift, AFPR, l.t. headers, double roller timing chain, ported plenum, otherwise stock. ( removed AIR pump and all smog stuff )

oh you're from florida, you don't need any emissions stuff, that is nice. I recommend the 24 lb SVO injectors because i think the 19lb is a little small.

Fred91GTA

Do you have an L98 in your car? This is because I was thinking about sending my injectors in to Cruzin Performance to have the injector cleaning service done. If you have the L98, then we have the same injectors since I have an L98 car. I may have to start looking for new injectors as well since mine are leaky.

1990GTA

Yes,I have the L98. I already got my SVO injectors, I ordered the 24# but I am thinking about sending them back and getting the Accel's. It just don't seem right to me putting injectors in that are designed for a Ford. And then there's the different pressure issue. Once I put them in and run the car then I can't send them back, If someone that is running the SVO's is reading this ... did they fit properly?, have you had any problems with them running to rich?, I'm getting a custom chip but can't afford it right now and I need to get my car running.

Fred91GTA

1990GTA, where did you get your injectors and how much did you get them for? I am definitely doing the Ford SVO injectors. I have a Holley AFPR so I'm not worried about the difference in fuel pressure ratings between the SVO injectors and the Bosch/GM injectors. There was a similar discussion about this strted by me on the GTA Source Page. One guy had an interesting idea. He has a '91 L98, which is the same motor as ours. He bought the SVO injectors and lowered his fuel pressure down to 37psi, and got the injectors to run at 23lbs/hr. His car runs smoothly and passed emissions according to him.

If it is at all possible, could you please check the parts numbers for me? I'm trying to get a set off ebay.

Also, what is the difference between Ford Racing, Ford Motorsport, and Ford SVO? Aren't they all the same? Their parts all look similar enough...

1990GTA

The part # is M-9593-A302 for the 24lb.They were $219.99 from Jeg's , a lot of people on here refer to them as SVO that is why I called them that. In the catalog it say's Ford Racing and the box they came in say's Ford Racing ( SVO).I have the Holley AFPR also but there are issues with the stock chip that may not be able to be compensated just by turning down the pressure. I'm just quoting what I have read on here , I really don't know. I have a few mods I am working on now so maybe it will need a little more fuel anyway. A lot of people on here use them so I guess I may just keep them , I have heard nothing but good about them except the fuel pressure issue wich can be remedied.

I know of a couploe people running the 24 SVO's(or FMS or whatever - Ford injectors) and stock chips. You can get what you want out of the AFPR. The Ford injectors drop right in, and work well according to all the info I've gathered on them. I've been researching this for a while, because I'm trying to get my FI to feed my new motor. I'm goint to run the SVO injectors and a Stealthram on a stock chip. Thats been done before too. I may need a little more than 24's though...my 355 is making around 425hp... - also, 1990GTA, where are you in Orlando? - I'm on Alafaya out by UCF -

1990GTA

Shagwell, thanks for the info. Do you know what fuel pressure they are running ? BTW, I live right down the road by Lake Underhill and Goldenrod .

Shagwell

not real sure - somewhere around 40-50 psi I believe. I may cheat mine for a while. I just read a TPIS article. They made over 400hp w/ the stock injectors, and AFPR, and their mini-ram. I'm going w/ the Stealthram, but still, if the delco's will keep up, I'm all for it for now. I can upgrade later, just gives me more steps, to ease the blow to the wallet. - What color is your car? - I must have seen you around somewhere before. I run around this town way to much. - I drive a burgundy GTA ragtop w/ a tan top.

Shagwell

nevermind - I looked at the pic - gotta start remembering to look first...

The Ford SVO 24lbs are rated at a different psi. So the 24lb SVO's will easily support your 425hp.

Der91Z

Running at 37psi seems a little low, i bet it would run better if he got smaller injectors and cranked the pressure up. the spray pattern just doesn't compare to one with higher pressure.

Shagwell

Yep, the 24# ones will support my 425. I wasn't thinking. Besides TPIS made more than 425 on stock Delco's. - Higher fuel pressure makes for a more pricise fuel spray. Not a noticable difference in power, but a little more effiecient.

Fred91GTA

True. I'll be lowering the fuel pressure to that low to get the car running smoothly just as a temporary measure. I'm still new to burning my own chips, and it's very hard to gather data and calibrate PROMs in the streets of NYC. As long as she's running and passes emissiones, I'll be able to get her out to were my college campus is, where there are wide open roards and I can gather accurate data and get my calibration correct.

Do you need to use the clips that lock the injector to the fuel rail
with the ford SVOs injectors?

1990GTA

I'm sure you do , but I have not installed mine yet. Still cleaning and polishing

86IROCNJ

I am almost positive you need to. When i put in my Acells, they needed them, so it should be the same for the Fords, no? I'll find out sooner or later.

Der91Z

iTrader: (1)

yes you need to put the clip on or that liitle o-ring seal will get deformed over time and cause a leak. I have seen this happen at the dealership many of times where the technicians forgot to put the clip on or put it on wrong.

86IROCNJ

Wow, and these guys are pros?! I still wonder why dealers charge so much for service when i hear "horror stories" all of the time. A friend of mine, one of his relatives went to a dealer for the basics. Well, when they rotated the tires, they never put one wheel's lugs on all of the way and the damn thing crashed on the way home. No joke! He was fine, just out of a car for a while, forget which brand though, an import of some kind i think. Someone else i know had their motor sieze up after a "routine" service. I think it was a Ford that time. My other friend works at a Toyota dealer and is only allowed to do oil changes for now. Hes been there since May with like 60+ credits too. Wonder when they are going to let him do some damage!?!? lol

This might be a little off topic, but at my local jiffy lube, some guy forgot to put the drain plug on all the way and as he was pulling the car out for the customer the drain plug came out and he left a trail of oil and i just had to say something to him before the customer got in and drop off. anyway, to keep this on topic. You must put the fuel injector clips on, GM wouldn't of put them on if you didn't need them, cause it cost money.
