It all makes you wonder why they didn't use 4-holes in the first place lol
Cheaper to drill one hole?

5.9 confirmed

I literally joined this forum just to confirm a 99 dodge 5.9l with the 703 injectors. I had been reading and figured i would try it. Bought used neon injectors and the recommended rebuild off ebay and was going good a week later. I'm getting roughly 2 more mile to the gallon both by the overhead and the miles to gallons math.

Just finished installing 703's in my 5.9. Pulled em off a few stratus's with 2.4l. All the neons I looked at had different injectors.

World of difference, smooth idle, better acceleration. Too soon to tell on the gas mileage yet.

Did this last week. 703's in my 4.0. Fresh fuel filter, mopar tune up kit and a K&N drop in filter. 200 miles later, my overhead went from 13.1 to 16.8. Haven't done the math yet. Great upgrade. Almost has tha fresh motor zip to it.


BTW: used reman injectors off ebay. $100

Would there be any benefit or problem with converting to uscar injectors using plug and play adapters such as those found on ebay? I recently picked up four different types of Ford 24# blue injectors and am debating on which set(s) to keep and which to sell. Here's what I have:

Denso F55E-A2E === out of a 2nd gen Lincoln Mark VIII 4.6 DOHC (basically same as a Cobra) - single pintle type w/Jetronic connector
Bosch 0280150947 === Ford p/n F1TE-D9A (4 hole Jetronic)
Bosch 0280155715 === Ford p/n F5DE-B5A (4 hole Jetronic)
Bosch 0280155849 === Ford p/n XF1E-A5B (4 hole USCAR)

One thing I noticed is that although all three of the Bosch injectors have 4 holes, the holes are much closer together on the 947 which uses the same pintle cap as the Denso injectors (which practically look identical to the 947). From what I've read elsewhere the 947 style is known as a Bosch type 1 or type 2 - not sure of the difference - and the 715 and 849 style are Bosch type 3 (sorry if it was covered here but 29 pages is a bit to read through without stuff starting to blend together).

I would try to keep all injectors of the same type in the engine. There are too many variables in injector performance (spray pattern, ohm resistance) plus adding adapters to mix and (try) match.

I currently have USCAR 24lb injectors with adapters in my 98 Mustang GT. I have a CEL "misfire" code, I'm not sure if it is one of my rebuilt injectors, an adapter or a plug. The engine is new, plugs are new and I'm not a happy camper.
My next step will be new injectors without adapters.

I am also in the process of building my own injector cleaning/ testing stand.

If you need some let me know. The only ones I have 8 of are the Denso and the 947...they're still 24# w/Jetronic and I can include the parts to rebuild them or I could rebuild them before I send them. PM if you're interested...I'm sure we could work out a very favorable deal.

I would be interested in a set of EV3 - 6 19lb's, set of 8. Due to health issues, ( I had a double hernia repaired as well as my RH knee rebuilt). I "farmed" the PI head swap on my '98 GT to a friends garage. He gave me a price, I was OK with it so they started. It was like having my house built all over again, if it was not this, then it was that, a cluster F___. My New PI heads from a East Coast Ford dealer's Ford Racing Department, were perhaps not new - purchase date to build date was too late to complain. The cam in one head would not turn, it had apparently been dropped on the cam cap. The cams are so radical that the valves hit the pistons. #2 set of torque to yield head bolts went to install a stock set of non-PI heads. Then came the anouncment that my NEW BBK headers did not fit, ..ya right. After 5 minutes of inspection, it was noticed the motor mounts were broken, mind you the installation instructions describe unbolting the mounts, lifting the motor to install.
My bill now doubled, I said just install the exhaust, I'll finish the motor. On the way home (2 miles), my $700 Basanii exhaust melted the plastic zip ties and fell off.
I no longer need 24lb injectors, 19's will be fine. I adapted the PI aluminum intake, headers are good as well as exhaust but the PI heads are for sale as well as the cams. To think I was going to ask them to install a 32V Cobra motor, thats still on the stand.

On a brighter note, I do have the '95 ZJ front signal harnesses ready for you.

Man...to say that sucks just doesn't say enough. I may have a set of 19's as well but will have to check. Send me a PM tomorrow to remind me if I don't let you know...and we'll firm things up with those harnesses.

the 703 injector from the mopars , are they from a auto or manual trans ? I'm going to get mine from a junk yard and I need to know before I start pulling parts off. I would think they are from a auto since the listing has some vans in it. thank you much.

If you're going to get the 703s from one of the 4 banger Stratus's or Cirrus's, you can read them before you disconnect anything. Same for Neons. I found they're way more prevalent on Stratus's and Cirrus's than Neons.
