Well I may have discovered a problem recently. I was tracing a strange wot leanout for quite a while, I had to set my wot enrichment to 65% to get it to the right afr! When I repalced them with some 28 lb/hr's the problem went away. The strange thing is that it ran at the right afr when I initially put them in...

bookrat

I'm still using mine and no problems so far. Try checking out http://stores.ebay.com/Mr-Injector?_rdc=1 This is where I bought mine. He gets them from junkyards but says only from vechiles that are less then 100,000 miles. then sonic cleans them replaces the O rings and tests them.

87bluebird

has anyone used these kind of injectors.do they fit better than the ford ones. earlier in this thread someone mentioned that the ford injectors were short and the o rings didn't fit. would the 3100/3400 injectors have these issues. also would the fact that there 17lb not 15lb make a difference. my bird has a completely stock 2.8 with 73,000 miles. and idle is really rough and the throttle response is really slow. what all would i need to get to switch out the injectors gaskets for for plenum, dielectric grease, and injectors. is there anything else i'll need to get. how much do these injectors cost and does anyone have a link to them. one more question which injectors work better the ford or the 3100/3400?thanx.

edit: this guy has them listed at 20 something. but does not mention if thats 1 or 6 injectors do any of you know?

southbay08

hi, the ford/bosch injectors do fit. All you need to do is use the clips or, we can apply a second oring on the bottom for you so they will be plug n play. We carry the bosch gen ll in 15lb which will be fine for the 2.8l. We have sold many of these injectors to members of the forum for your particular application and they have been very happy,, no problems at all. They are $125 for the set. They are flowtested and flowmatched. If you have any questions please pm us or give us a call at 516-492-6504

The picture shows a Multec injector. IMHO, a waste of time to install them even if they were free. Get some Bosch injectors, even if they came out of a F0rd.

OK, I've been reading this thread over and over, checked the links, read all (well mostly all) the various interchange info, flow rates etc.

It appears the F1ZE B4C injectors are only 14 lb injectors (listed for the 3.8 litre engines on Motor Man's page.) I would really like to replace mine with 15lb disk type injectors but where to get them and which number is the right one seems to be a bit of a mystery. Maybe I missed something? Can anyone help me out here guys.

Also, any insight would be appreciated. Just bought a 1990 w/3.1 litre and 191,000 on it. Runs pretty doggy but the basic tune - cap, rotor, wires, plugs, filters, were a good start and helped. Running sea foam thru the power brake vacuum line provided the usual amusing white smoke. Also running 25% Marvel Mystery oil in the crankcase and in the fuel tank ~7 oz to the tank full. Seems to be very gradually running ever slightly better so that is what makes me think the injectors (probably never changed) will make the difference if I can find the right ones.

southbay08

We carry them...the number is 280150941. They are flow rated at 14.5lb @ 43.5psi which would be absolutely fine for your application.

www.southbayfuelinjectors.com

90RED3rdGEN

OK Southbay thanks for the response, but these are not the Bosch 15 lb injectors tauted in this thread. Also according to your website the Bosch 15 lb injectors listed are pintle not disk type which the guys on this thread say are the way to go due to spray pattern and operation/performance improvement. I'm ready to order if these are what I want but would like clarification.

southbay08

yes the injectors that i have listed are pintle type, but we also have the disk type in stock. Again the number is 0280150941 FOSE-B5A. The other injectors that are listed on this thread are from Motor man. You have to understand that there are many fuel injectors that are the same exact injector in every way but the part number. If it is the disk type that you are interested in then give us a call and we will be more than happy to help you. 516-492-6504

I just picked up a set of f1ze b4c injectors at the local junk yard out of a wrecked mustang. Where do i get the right size o-ring's so they don't leak? I messed one up pulling em out so I'm going to replace the o-ring's and the plastic tips.

86ttopbird

Those Mustang injectors might be from a 3.8 which would be too large for a 2.8. You just get new O-rings for your car not the Ford as the Ford ones will be too small. Just make sure you lube them up when installing the injectors or they will roll up causing a vac leak or worse, a fuel leak. You want to look for injectors out of a bronco II or a ranger with the 2.9 liter V6.

firebird904

I read they were 14lb injectors.

jensen73110

^Depends on the year of Mustang.

A few days ago I had some 19 lb/hr Ford "yellow tops" land in my garage for basically free, so I'm gonna give those a try. Yes, I'll need a tune. I'll eventually post how it goes....

firebird904

these have a gray top and have the f1ze b4c on the side all I've been able to find is that they were 14lb injectors...maybe I'm wrong

here's a pic ford injectors are on the left

90RED3rdGEN

I ordered my set from Southbay. Should be here Tuesday. A few things to remember if you order some (to the best of my knowledge after a long discussion with Julie at Southbay):
1) the discussion thread indicates the Bosch injectors have a better spray pattern and atomization
2) Bosch has their own part number for them. Ford's is the F1Z denotation
3) You want the disk type of injector, not the pintle type. This is a crucial point as the disks perform better.

southbay08

That part number is a 14lb injector. Many injectors out there are made from the same manufacturer, look different, look the same, have different part numbers, 4 spray, pintle, but.....have the same exact flow rate.

firebird904

I finished putting mine in today and I must say its made a huge improvement on throttle response and the idle is much smoother than before.

jstrdn90rs

Sure mine did the same thing..I think they maybe a little on the lean side on upper end (can't confirm it ,but I dont see upper end much) I tried 3.4 injectors (GM) and the idle was irratic and fluctuated up and down,and blew out my O2, but highway speeds it was awesome.I would like to find something a little in between but what would fit?.Dont own a junkyard so thats out of the question?

90RED3rdGEN

Hey, writing because it looks like you have had quite a bit of experience with this injector business - also because we have similar cars 90 RS 3.1L

When I took my top end off to have the heads done I very carefully observed parts, took lots of pictures, and labelled everything in zip loc's etc. The injector harness had numbers 1-6 on each plug in connection so I mistakenly assumed they were matched, the cylinder numbers 1-3-5 passenger side, 2-4-6 drivers side.

Installing injectors and then attempting the harness I have learned I was wrong. there is no way this numbering system would work because there isn't enough wire to reach between the 1 & 6 plugs & injectors. Now what?

Is there a way to test or match these plugs on the harness to the right injectors based on electric signal?
If so, how.

RBob

iTrader: (1)

It doesn't matter which plug goes on which injector. Route them so that the harness fits properly.

It is a batch fire system. All six injectors fire at the same time.

RBob.

90RED3rdGEN

Can do, will do, and I like this answer but help me out, i don't understand how this works. If they all fire at once isn't there fuel going out unused on the exhaust stroke on some of the cylinders?

RBob

iTrader: (1)

Going through Stan's injector list here are a few candidates:

0-280-150-237 14.55#/hr Buick v6-3.0l

0-280-155-600 16.55#/hr VW

0-280-155-703 16.75#/hr Chrysler 4-2.4l, Dodge 4-2.0l
0-280-155-705 16.75#/hr Ford
0-280-155-819 16.75#/hr Ford 4-1.8l

0-280-155-821 14.25#/hr EV6 Ford v8-5.0l
0-280-155-844 14.30#/hr EV6 Ford v6-4.0l
0-280-155-863 14.66 #/hr EV6 Ford 3.0l

Note that the EV6 are a small body injector that takes a different connector.

The flow ratings listed are at 43.5 psi.

The best bet of the bunch are the Buick injectors. Most likely they are a drop in and have the proper length. Along with having the slot for the clip.

The Bosch part number can be found on the injector. The top plastic piece will have it. Hitting a u-pull-it and browsing for these would be a good choice.

RBob.

No, during the exhaust stroke the intake valve is closed. The fuel just sits there on the back of the valve and runner walls until it opens.

RBob.

90RED3rdGEN

Oh, DUH! on my part. Makes perfect sense. Thanks for the info RBob.
On to getting this thing running. Really looking forward to turning the key.
When I bought it, ($450) it barely ran. Cracks between intake exhaust valves on both heads, cat converter totally trashed and plugged up sp absolutely no power (surprised i even got it home), and it had the usual 191,000 miles of grime on everything under the hood. It is coming back together nicely.

Pulled the interior completely out to clean everything from the infant that the chick turned loose with food in the back seat on a regular basis. It is just coming back together and should have it running later today.

Will need a paint job too. Been 30 plus years since a project like this and I'm having a great time with it.

when I figure out how to post pictures on this site will begin a photo log to share.

GTA50

Hmmmmm, this has got me thinking. What size injectors would be recommended for a modded 2.8?

I've done a bore (30 over) plus 3.1 rotating assembly. Balanced and blueprinted, high volume oil pump, double roller timing set, port and polish of heads, performance grind on valves, 1.52 roller tip rockers, ARP studs, and 260 grind cam complete the internals. Also, I done headers, cold air intake and a cat back exhaust.

Car runs great - lots more power, but when I did the build, I kept the stock injectors. The car does seem to "hunt" at idle for the right setting - but I'm thinking that is more of an ECM thing (and I'm on a steep learning curve for that one LOL).

What I should also mention is that I have about 450,000 km on the car!! So, changing injectors is also a possibility.

southbay08

one of the most important pieces of information that you need when trying to figure out what size injectors you need for your application and or modded engine is to have an idea of what kind of horsepower you are planning to run. If you have that info it is very easy to figure out what size you will need.

GTA50

If I look at the old hotrodder's guage of 1 to 1.1 hp per cubic inch, I'm probably somewhere about 180 - 190 hp and could push it to 200. I haven't dyno'd the engine but the butt dyno puts it in that range. So, I would probably size for 200-250 (based on after I tune it as well).

RBob

iTrader: (1)

A decent choice is the Bosch 280-150-901 injector. Found in Buick 3.8l FWD engines. EV1 design, 18.55#/hr, will support 210 HP at .45 BSFC and 85% duty cycle. They are also a perfect fit, proper length with GM o-rings and the retaining clip groove.

Note that you WILL HAVE TO TUNE to use these.

RBob.

90RED3rdGEN

Hey RBob, sounds like you have some electrical now how so here goes with the next question. Everything is back together, heads, intake, plenum, TB, etc. Hit the key, heard the fuel pump pressurize the system, motor turns over but nothing. Checked for spark - none at the coil. Anything obvious I missed or should check?

Can a coil just go bad from taking it off and cleaning it? While into the engine I replaced several pieces of plastic conduit on the wiring harness as it was cracked and heat aged. Taped any frayed or burnt wires and carefully checked them all. There isn't very much wire between the coil and the harness so it should be ok.

Any ideas?

RBob

iTrader: (1)

Double check everything you touched. Grounds bolted onto the back of the head(s)? Any fuses blown? Check all connections for bent pins and such.

To check that the distributor is sending reference pulses to the ECM. Key-on, engine-off. Listen and wait for the fuel pump to stop (about 2 seconds).

Then crank briefly, then listen again for the fuel pump. If the distributor is sending DRP's to the ECM, the ECM will fire up the fuel pump for another 2 seconds at each cranking.

Can pull the injectors fuses to prevent flooding the engine.

If no fuel pump, then check the power to the coil/ICM, check the two-wire pigtail between the coil & ICM. Pull cap off distributor and make sure the rotor turns as the engine is cranked. And so on.

RBob.

90RED3rdGEN

Thanks. Fuel pump cycles like u describe.rotor turns. No spark from coil wire. How do I Chekhov pigtail at coil w/multiple meter? Set to dc & plug lads into sockets, & looking for what - 12volts?

90RED3rdGEN

Is there a way yo test a coil? It worked fine before the tear down

Whats up people...


so question...have any of you guys or anyone on here used these injectors

E67E-B4B F1ZE injectors

I bought them awhile back and someone told me its to much for my camaro. I did put them in but thats when my Camaro was acting up and with a cracked upper manifold that some idoit did.

So ya, Just wondering if I should just go back to stock or stick with these. I did feel a difference but felt like my stock injectors worked better or maybe it was just me.

Thanks guys

After a lot of rough running, hard starts, terrible hesitation, and stales at red lights I finally broke down and ordered some 0280150941 FOSE-B5A 14.5lb injector from southbay and they worked great! My car is no longer embarrassing. Everything it way better. I did find when I took the old ones out though that two were cracked pretty badly at the bottom. Which is probably one reason why it was so bad in the first place.

So, is this what we're looking for?

I have the stock injectors and fuel pump in my 86 TPI. I make a decent amount of HP as is, but now that i'm tuning the car, would it be wise to buy bigger ones like 22lbs instead of the stock 19lbs i have now? Also, going to be going to higher pressure fuel pump as well...

thanks!

Yup a upgrade fuel pump is needed in order to keep up withyour upgraded injectors. ive been reading up on this form and still havent figured out whice is best for my 3.1.

ok guys, I have an 89 rs 2.8/700r4. I'm planning to do port and polish, headers, intermediate pipe with a high flow cat. also want to do a shift kit, with the throttle valve/plunger set from summit to open up 4th gear to WOT shifts(also have a trans cooler from a GM truck picked up from the swap meet as well). doing numerous suspension upgrades.

I am aiming for around 200 to 210 hp, with 50-75shot nitrous fogger on a 1000 shot tank, rigged for the go button and not controlled by the ecu or equivalent. I'm going more for a circuit course car, but not with so much horsepower that it makes it a pain to drive in traffic. It is a daily driver.


Currently on the car is a hollowed out cat with a thrush welded muffler(Sounds AWESOME), aftermarket two tooth timing set, custom cold air intake that i made myself with a $10 elcheapo intake kit from a swap meet(average air temp @ 60mph - 59 degrees/lowest 57 and highest 65). 16 inch aluminum rims with some 225/60r16 General Altimax RT, overall i am extremly happy with the tires. Making slightly better power than stock, and the car screams on the highway.

My question would be which of the injectors discussed in this post would be ideal for what i am planning. I definately want the disk injectors, probably pulled from a junkyard.

This is a long term project so time is not of the essence, but i would like to get injectors next because as far as i can tell, my current injectors have 200,000 + miles on them.

Any input will be nice, as i will be coming here quite often for ideas, help, and advice



(before you bash on me for buying general tires, they were $72 a tire when i bought them from tirerack.com, and on a scale from 1-10, scored 9.5 on dry and wet traction with excellent wear durability, with over 160 reviews, my only quam is that they suck in snow and ice, but i dont think its snowing anytime soon in florida.)

Hey southbay, are the stock 19lbs injectors good enough for 270HP or more?? I'm tuning the car now and will definitely be netting much more horsepower than my stock tune.. Do I need to get a larger size injector like say 22lbs? If the 350 engines makes 245HP and have 22lbs injectors, and I am making more HP with smaller injectors, I would assume that going to a larger injector will give me greater HP numbers (along with a tune ofcourse)?

EDIT: http://www.injector.com/injectorselection.php

Found out that my injectors are at their peak for HP.. It's time to upgrade to larger injectors and higher pressure fuel pump!

southbay08

The 22's should be fine for 270 to about 290hp @ 43.5psi.

hellz_wings

iTrader: (2)

wheel horsepower or flywheel horsepower?

southbay08

flywheel

hellz_wings

iTrader: (2)

So then the stock 19lbs injectors are good for how much HP then?

southbay08

You can go either way with these injectors. At 43.5psi @ the fly wheel the 19's are good up to about 270, if you need a little more you can just bump up the pressure. If you go with the 22's....again at 43.5psi you will be good at least up to 295hp and if it is too much you can always back off on the pressure.
It all depends on what you are looking to accomplish and how much hp you are planning to actually run.

hellz_wings

iTrader: (2)

43.5 is the stock pressure IIRC.. But how does that pressure relate to the tune in the PROM? Or is it just an overall increase in fuel pressure? From my understanding, the computer controls how much fueling the engine needs at certain RPMs, LV8's, g/s of air, etc.

southbay08

it's an overall increase in fuel pressure
