Jeep Strokers

I have been tying to figure out what fuel injectors will fit my stroker(2003 TJ). I bought a set of Ford injectors that I thought would work(recommended buy five o motor sports). The part numbers on the injectors are XR3E-C5B, 0280155865. From doing more research, it seams these flow 24lbs at 39psi. With the 2003 jeep fuel psi @ 49, are these injectors going to be too big? I have also looked at the accel 24# injectors. They are rated 24# @ 43.5 psi.

I'm having a hard time trying to find articles about choosing fuel injectors. It seams I always come up with just an injector calculator. Putting numbers in the calculator,I come up with 26# injectors, which I have read are too big. Now I am finding out there are EV1, EV6 injectors...I am sooooo confused . Does anyone have a link to a good fuel injector site, or point me in the right direction?

Look for injectors 0280155849, was used in Ford 99 Taurus/Sable. These flow [email protected] and have EV6 connector as in your harness.
You can get a used set for $30 off eBay.

Will flow 25.47 @ 49PSI.

The LT1s I'm using are rated 24#@43.5psi and are 25.5#@49psi. I've maxed the duty cycle via PSC in order to get 12.5@WOT in 5th, so I'd say they're a bit small for my app but should be good for some strokers. They have the 6-hole pintles and are ev1(better for 99 and under).

hi, gradon was looking to find someone with a running stroker because i am in the process of building a 4.6. There is a lot listed on the site and just looking for info on what type and size to go with . I would appreciate any help or suggestions you could give me.

There are a bunch of injector options, but first you need to know what system you're working with. 87-95(renix-obd1) 4.0s had a 39psi rail w/ return and the 96+(obd2) had a 49psi rail. I believe 87-98 injectors are ev1 style connectors and 99+ are ev6. I use mid-90s LT1 injectors that are rated 24#@43.5 psi and flow 25.5# on the 96 49psi. rail. I've tried the single pintle Ford blue tops(24#@39psi, ~27#@49psi), but could tell that it ran better with the lt1s.

i have a 98 with 49 psi. thanks for the help , just alot of info floating around and not sure what the best way to go would be. I have the whole harness for the ev6 setup that came with the 99+ intake i bought , so I have a couple of ways to go.

I have the XR3E 9F593 C5B from a Ford Cobra. I feel they are too big. They flow about 28lb at 49psi. I'm going to try a set of 0280155849 from a 1999 Ford Taurus and see how they work out. They flow about 26lb at 49psi.

There is also the Ford XR3Z 9F593 A4B / XR3E 9F593 A4B which flows about 24lb at 49psi.

ok when you try them out let me know how they workout.

Ha.... how long would you like to wait?

oops had a mental block . slipped my mind that you are not doing so well with your project. just a wild thought on that issue , is it possible that when installing the cam you are accidentally somehow putting a burr on the cam bearing when you are installing the cam?

i think i may be facing a similar problem. my XJ is an '88/Renix with a '94 year 4.6L stroker from Titan engines (I know, I wish I hadn't). intake mani was updated to '99 as well, but the TB/fuel rail are '96 and bored to 62mm. I had gotten the 24# from fiveomotorsports as well, but seems to be running rich and the plugs are black as hell. I did not initially install the motor, twas a good friends uncle/trustworthy mechanic, but no jeep whiz. now 2 years later i am trying to bring her back to life. for one I don't know that he ever even properly adjusted the TPS which he somehow mated to the newer TB without using hesco's adapter. seems like larger injectors/higher psi fuel rail could would cause it running rich, but i think i do need to get a good af meter. does have an adjustable fpr installed, but i can't remember about the MAP. anyone else out there with a renix XJ with newer motor/intake setup that can comment? thanks

So your injectors are 24# on the renix 39psi setup or do you have the FPR set at a higher psi? You should turn down the FPR if it is adjustable. If not, try a 21-22# injector and then take a look at the plugs.
