View Full Version : Mustangs Fuel Injectors Are Awsome!

I have been struggling for the past 4 months with BAD MPG and slowness at the start. I use to see the fuel gage needle go down so quick it was awfull. Th obc always read 8-10 mpg and now it read 17.3 but actual from pump with 4 gallons of gas gave me 16mpg!

The car use to be fast when floored at 35 mph but now the car flies big time. These mustang injectors made a HUGE HUGE difference in both MPG and POWER. The power is just amazing, I gunned it and within 2 second I had to hold on to the steering with both hand. I'm just not use to that kind of pull so kinda got scared!

If you want more mpg and more power get these MUSTANG injectors! You won't regret it.

Bosch - NEW (yellow ones) Thye can also be purchased at ebay for around $80.00 used, I had then cleaned at http://www.cruzinperformance.com/

From a scale of 1-10 I would say 8 if you can change spark plugs on this model. I don't know if they will work on 2.8 check the website. I'm sure you can get some others that will fit on yours. As long as they are NOT the original injectors but that will fit your car you will love it.

I bought them used at ebay, but when I put 4 them on the car the car started shaking like crazy. So I send them to get cleaned. So total with shipping was 80+103.05= $183.05. Try these http://cgi.ebay.com/ebaymotors/Fuel-Injectors-Design-3-19-Ford-Mustang-BMW-4-6L_W0QQitemZ150058486034QQihZ005QQcategoryZ33554QQ rdZ1QQcmdZViewItem

Lokks like a great deal, specially if they are trluy cleaned. I think I saw brand new one at ebay for $200.00 which is good.

The hardest part about this job is taken out the old one. They sit very tight between the fuel railing and the block. It will feel as if you missed some bolts and so they don't want to come out. The key is to make sure all the bolts are out (8-10 of them) and the top and bottom clips of the injectors. Than use a little bar and put it between the railng near the front or back injectors and prye them up. They will come loose. Than just pull the old injectors out moving side to side in and angle and they come out.

Now the new one just put right in, no clips, nothing, awsome. The railing pushes against them for a tight perminent seal. Keep in mind there is a lot of little stuff that has to come out to get to the injectors. common sense will guide you. JUST MAKE SURE YOU DO THIS WITH THE CAR COOOLD!
There will be gas that will come out from the injectors no matter what you do. I used a pressure wrench and taped 2 quarters between the teeth and squezed the fuel line on top driver side and it stopped the fuel from coming in to the fuel railing. Than I started the car to get as much of the remaining fuel burned. Car turned of and I was read y to go. I disconnect the positive and negative battery as well.
If you guys try it let me know if you need some help, it';s not that bad AT ALL. Just takes tme and patience, pay attention and you won't go wrong.

None at all!One thing I did notice was that once the car warmed up the idle was a little higher than usual. After a drive of about 5 miles the computer set ip back perfectly. Whoever decides to do this will come back here and post how great this update is. Don't be afraid and go for it. By the time you get "input" you could have finished the job. I too was looking for input on this upgrade and most people were against it (because they never did it so it was just theories). So glad I did not listen. I found one guy who did this with a chip upgrade and he loved it. That is why I'm looking to see if anyone has a chip for this year and model.

From what I understand, when doing a "chip upgrade" the part itself doesn't get replaced, but it is the software that gets modified.

Can anyone confirm this?

I have only installed 2 magnaflow cats, 02sensors,bosh plugs, fuel pump and fuel filter, k&n filter. But even after all that I had 8-10 mpg. Than I installed these injectors and everything came alive. Have not installed nothing that would make it "modification" accept for maybe the k&n filter but that's it.

"From what I understand, when doing a "chip upgrade" the part itself doesn't get replaced, but it is the software that gets modified. "

Even if it's software a little bit is better than nothing. Hope someone will come in here and tell me where to buy any chip for a 95.

Plik: when you do an "upgrade" to the computer in any 1995+ 7 series it is a software upgrade (firmware) and not an actual hardware upgrade or replaceable "chip."

Hence why it requires you to take the car to a shop or send your ECU into or swap it out to have the upgrade done.

They look the same as the ones I installed. I like the 4 big hole sprayers. The old ones I took out had 2 tiny ones. If you plan to get those they will work great. You should try to cross reference them, I'm sure they are the same as the ones I put in. Today I went to the mall (30 mile ride) and got 16.1 mpg with 66 miles total of gas with 4 gallons I added(already had 36 miles on the car before going there). So the on board computer is pretty accurate

So what is the major difference in the fuel injectors? What size is factory? Why just stop at 19lbs? Will this increase or decrease my gas mileage?

PS: 19lb mustang injectors are super cheap and easy to find. This is a great find if it really works.

41 bucks!

And by the way, mustang is just a brand, the fuel injectors could come from almost any 87+ 302 based engine. For example: Explorer, F150, Cougar, Mustang, Thunderbird, etc.

speedmon

12-07-2006, 01:54 AM

Does anyone here know what the stock injector size is for a 740 is? This may vary by year and engine size.

Bosch makes fuel injectors of all sizes as I run them in my Z06. Yes, Mustang SVO injectors (from 28 to 30#) are a common upgrade in 01-04 Z06s. Lowers the injector duty cycle and increases torque, sometimes up to 20lbs at the wheels.

Given that the ECU software remains constant, that is the signal to open and close the injector, any power increase due to injector change can be due to 2 reasons. Given the fact that the injectors were not just old and dirty and not working.

1.) the stock 740 injectors were undersized and bouncing against their duty cycle (#of open and closes) at full throttle. Therefore maximum torque was being limited by the injectors.
or
2.) the SVO 19#s the thread starter installed could have lowered his Air/Fuel ratio thereby creating more torque, thus the feeling of increased power and happiness. Lowering the AF ratio too much is in effect leaning an engine out (less gas more air) and if you lean it out too much the combustion chamber will run too hot and burn up. The way to check is to measure the AF ratio on a dyno to make sure you're safely within tolerances.

Injectors basically all work on the same principle. I'd be interested to know if the thread started installed bigger ones or smaller ones?

12-07-2006, 08:40 AM

I just want to know about gas mileage! :D

benz2bmw

12-07-2006, 09:50 AM

First of all I can say that my stock injectors where not dirty. If they were it was very little because the car ran great and with no shakes and veru smooth idle. I have had the mustang injectors for about 2 weeks now and the car still gets good mpg on city 15-16 and highway I got up to 24-28 at 50-65 mph.

I don't know if these injectors are bigger than stock but from what I have searched and read a review of a guy who did this (which made me go for it) the injectors spray much BETTER than the stock ones. So you get a better "mist" which is easier for it to burn and therefore for power and better mpg.

I also read that bmw uses these as an "upgrade" for older bmw's such as mine (95). I love these injectors and they are easy to install and well worth the time and money for the upgrade. If anyone has 740s from 99-2001 I would first make sure that there injectors are better than the ones they have on their car. I know that for 95s and perhaps up to 98 these will be better. At least for my year I know it made a huge difference and the car runs fast when I want it to.

740iMC

12-07-2006, 11:06 AM

I really want to know what the injector lb is. If is less then 19 I can see the benefit I would go for 24lbs though and maybe have the MAF sensor recalibrated.

They are truely cleaned... It's weird how I stumbled upon my own auction on the web. I can offer these for $75 / set shipped to your door. You can contact me via eBay to verify my identity. I have about 15 sets which came in the mail today from one junk yard I will be cleaning, flowing within 2-3% and should have about 13-14 sets depending how many duds there are.

I used to look at this forum a lot when I was looking to buy a 3 series last year. Pulled the trigger on a GTO though.

If I read this thread right, any Ford v-8 302 from 87 and up will have these desired injectores in them? Or is there something in particular that I have to look for? These will be going into a 90 750. I have quite a few "yards" around me that have these newer vehicles in them. I always had need for the 88-91 gm injection stuff, but not the fords until now.

there is a point were putting on a larger injector will have adverse results. The standard program ECU will operate within certain limits, as long as the O2 sensors can function to within the specified fuel/mixture ratios pre set by factory. In other words the fuel to air ratio must be able to be maintained as close to a 14:1 air to fuel ratio. I do not know the max output rating of the biggest injector that u can use, but if you over do it, a rich mixture will be certainly obtained, more noticable at idle and low speeds. This over rich mixture can do serious damage to the O2 sensors as well as the cats. Very expensive. I run 50 lb injectors with a s/c with the proper programming get awsome power and performance. Without the s/c but with the hi-perf intake and air induction upgrades you can run 30 lb injectors with programming. Without programming i am not sure what size u can run. Keep up the postings sooner or latter it will hit the wall.

THe injectors work well, but they flow too much. I was adivsed that .5 lb/hr would easily be handled by engine management. It is..but it pulled the mixture full lean to do so. Which means sometimes I am too rich like idle and nothing can be done about it. MPG dropped too.

Yeah my new Five-O-Motorsport injectors have caused my cats to over heat and go bad in six months or less from running rich but I have some other problems too. It doesn't help the air/fuel ratio (currently mine is like 12.5:1 and stoch is 14.7) when the idle air control valve is shut constantly so I am running rich from two things but man do I have power out the ass!:redspot

Like I said, for a modified engine they are great, but i will probably go back until I run my FI.

Its hard ti succesfully mess with stock. If you want to go a little richer, runner a FPR from bavauto.

I am stock other than Bav Auto coils (which isn't much) and the injectors so it is a nice change with the added power.
