neon injectors
Is anyone running neon injectors? What does it do if i were to swap them out? Anymore power?
|
A little better gas mileage.

Neon? Like a Dodge Neon?

i did it a while ago and i feel it was well worth it, i havent measured the milage, but im sure it helped a bit. I noticed it had way better throttle response and it never stutters now. You want the injectors with 0280155703 on them. I believe they are in the 2.4L from 95-97.
This might help too, https://www.cherokeeforum.com/f2/mor...-13848/index2/ |
I'm swapin' mine out tommorow....I'll post if I noticed anything!

those year neons never came with a 2.4 so stick to the stratus's
|
Ford blue top?
|
|
Did mine yesterday, no real increase of power, but the throttle response seems better.
|
Got mine swapped today...as stated before there is throttle response difference but power wise not noticable....
|
anyone ever try this on a 5.2 zj
|
I'm looking at doing this swap too within the next week so i'll post up some results too :thumbsup:
|
I have a set of injectors from a neon numbers 703's for sale. I just swapped mine you can check my build thread in my sig to see. Super easy to do and while I didn't notice any gas mileage gain I have noticed better acceleration. Well worth it imo.
|
i dont mean to jack the thread...but does anybody know if the #703 injector from the 95-97 2.4L is a plug and play for a 97 xj? or should i be taking the connectors from the 2.4 as well as the injector?
side note...has anyone run into the issue of the ECU having to relearn the timing/duration of injection because of the differences in the two injectors? or are they rated the same, just the neon has more orifices? |

The 2.4 and Neon 2.0 injectors are the same.
|
I checked my mileage after the injector swap, gained 1.5 MPG.

Ok, the last tank of fuel averaged out to 17.8 MPG. Before the swap I averaged 15MPG, so a 2.8MPG gain is huge for a simple injector swap!
|
would this swap work for an H.O engine?
|
Just to make sure what im reading is right, the neon injectors -0280155703 from 95-97 are a direct plug in to my 89 renix right?
|
i did the 703 swap to find out that on my 2000 xj they r to short so i got 784 out of mid 90's stratus and they give better fuel mileage and response, revs up alot faster with no hesitation. they are direct plug and play with 4 hole instead of 1
|
i know you guys have been talking about this injector swap for the 4.0 but will this swap also work on the 2.5 in a 95 xj?? thanks guys
i love cheap upgrades!!:thumbup: |
i beliieve that they would work. & u only need 4. less money.:party:

ok good to know.. i figured it would work fine. since the 2.5 is pretty much the same as the 4.0 just with 2 less cylinders.. so i figured the bore and stroke / injectors would be the same.. correct me if im wrong but isnt the reason why they injectors increase mpg / throttle response etc is due to the spray pattern right? cause ive read that our stock injectors have a one hole spray vs the neon 4 hole spray? thanxs for all the great input guys
ps i was born in manassas va too so good to see a fellow virginian... except now im a west virginian lol |

Got smoother throttle response, smoother idle, and better gas mileage. Power wasn't noticable. I thought the 2.0 was shorter than the injectors from the 2.4?

I'm considering this upgrade like everyone else...just a couple stupid questions about it: 1) how hard is it and are there any writeups for step by step on here (searched tech and didn't find one) 2) will this work on the later versions on the 4.0 in a TJ motor?
Although the Cherokee isn't a daily driver, I've got Dixie Run coming up and don't need to screw up something that works fine as is..just doing the mod if I can make it a little better and it's not all that bad, then why not right? thanks |
looks like I'm off to pillage 3 neons, need 2 sets one for me and one for my GFs 96
|
what do you guys believe is better neon/stratus or mustang injector swap def. want 4 orffice
|
Sure am glad I joined this forum... we have a 1996 Cherokee with the 4.0 and two 90's Dodge Neon... and two spare engines sitting in the garage! Heck, they don't need the injectors, right? :w00t:

I know this thread is old but a guy came over and said that he did the swap and had a huge power difference. he con tuned to tell me that before it wouldn't really do a burnout then he did the swap and had them tires turning like it was nothing and had great fuel milage but what i don't understand is would you loose fuel pressure because now your dumping more fuel and i wonder if it would make a difference to run a bigger fuel pump?

Did the 703 swap and 99+ intake manifold at the same time. Noticed a bit of power increase but mostly better throttle response and the jeep runs smoother. Definitely worth it.

This might help too, https://www.cherokeeforum.com/f2/mor...-13848/index2/ So do we need the srt4 investors? Cause they are impossible to find used. |
