Most you wanna run on a 4.0 is about 21#. Anything over that you'll just be wasting fuel and running rich. Even the 849's at 24# should only be used with a minimum of a bored throttle body and a true cai (snorkle), but are better suited for a stroker.
For your 93 you can run the 710's, just know that you won't be able to use the retaining clip. You can use your stock rail. The slightly higher pressure allows more fuel to flow, but it's the 4 hole nozzle that creates a better mist compared to the stock 1 hole.

 

okay sounds good, I dont wanna run rich or wast any fuel. You think the 21# would be best or should I just go with more of a stock one. Also you sell these right? How much would six of these ones be.

 

I don't have any 710's right now. I should have some 703's (Neon version of the Ford 710) this weekend though which I think you'd like better than the 710's. You can also check with Programbo to see if he has any ready to go right now. He and I both sell sets for $60 that are fully cleaned and tested.

 

okay that sounds fine if you think id like the 703s better, ill take ur word ur the expert here it seems. Just to clear up one more question. With the 703s I do not neeed to switch out the rail right?

 

You don't do anything but swap the injectors. New o rings of course.

 

correct. And I believe Programbo includes new o-rings with his sets, just like me.

 

Sweet thanks guys! Sorry for all the questions. Cant wait! Hey no rdplz shoot me a pm or post up here when you get those injectors together will yeah!

Ohh one more question about the memory wipe on the computer. I have a short in my headlight switch somewere(headlights still turn on, but rear tail lights wont. couldnt find short so re wired tail lights) I still use stock headlight switch to turn on headlights. but i use a diffrent switch to turn on tail lights. you think this would effect anything when reprograming memory?? Any way I can try and re set it befor i do the swap and know if it worked?

 

It won't affect the reset. As long as the headlights come on it'll be good. And yes, I'll let you know when I get a set in and ready to ship.

 

noob question here, how do you relieve fuel pressure?

 

push the schrader valve on the fuel rail (looks like a big tire valve), have a rag handy and make sure the engine is cool to the touch

 

Thanks much!! I'll try and do it tomorrow and write it up

 

My friend has a 05 Unlimited with the 4.0 in it, would his Jeep also need the 1 to 4 Injector up date, or is it already good to go?

 

No rdplz, which ones would work the best on a 98' auto?

Ive been looking at doing this and now that I have a new map sensor and my mpg are back to around 17-18 Im ready to pop these in.

You still reconditioning them? $ set?

 

703s

 

Hey Dukie, how are things? Waiting till the drive dries out a bit before I mount those brake lines. Then my bastad packs!


How do you like your 703's? What kind of effects have you seen from them? I figure it would be nice to swap them out cuz I will be living high altitude better atomization would be a plus!
