0280156007 VS. 784 Injectors

I see a lot about the 784 injectors but not the 0280156007. Has anyone used them?

Also seems like I see a lot of "short term" reviews along the lines of, " I just put these in an hour ago and they run good" but no long term reviews...e.g. I have had these on for a year now and I am still pleased......


So do you guys have any long term reviews?

Just stick to what's well known.
784s for your 99+ work fine from stock to stroker.
The computer adjusts how much fuel is sprayed anyway. The only difference is the spray pattern.

Yea, I was just curious, I see a lot of people say that they installed them, but I don't see any long term updates... my curiousity is spiked, I have to know!!!!

Plus the BOSCH 0280156007 flow less, so I would assume they would tend to give a better MPG than the 784

I don't know why anyone would run a injector large enough for a stroker in a stock engine (this includes the usual bolt ons). The PCM is already programmed a bit rich on the top end and running larger injectors just makes it worse, not to mention screwing up the fuel trims. The 007s are very close to your stock injectors in flow.

Just stating that I had heard people use them in their stroker build.

I rebuild 784 and 703 injectors
And I personally have 784 in my 99 and like them a lot

831, is yours a DD or a trail rig? I am setting up my DD. I really do think Taylan is right but I just hoped someone who had actually done the swap would chime in.

Just updating. I ordered the 007 injector I will report back when I see results. I do want to note that I replaced my gas cap( finally tracked down the gas smell) and I have seen an increase from 17.7 to 20 mpg. I have put 400 miles on the jeep since the gas cap but so far best 10 buck mid yet.

I've run the 007 injectors for over 6 months now in my 00. Work great. Long term fuel trims are less than 5%.

I'm running the Ford orange injectors.

They run fine.

But with what year? And what do your fuel trims look like?

1999.

Down the basics, I get about an extra 30 miles to a tank with these. In all honesty, there's nothing else to brag about.

Re: 0280156007 VS. 784 Injectors

Thirty miles to a tank is a pretty big difference in the long run... at least from my perspective.

So I got mine installed yesterday (007s). There is no difference so far in "peppyness" or in starting faster.... I will be taking a 400 mile trip this weekend and I will report back on gas milage. My old injectors looked to be in great shape (14 years old and 150 miles... they looks almost as good as the refurbed ones I just bought).

With changing injectors, resetting the PCM is recommended so it learns the new injectors faster.

Really I would expect 0 performance gain unless the stock injectors are dirty. The PCM will maintain 14.7:1 AFR in closed loop (most of the driving). Sure you are getting a finer spray, but you also have to take into consideration that the stock injector is firing on the back of a very hot closed intake valve.
