Has anyone done this or can anyone point me in the diection of a write up of what it takes to do this?

 

Got mine of Ebay for $20. Just unbolt the fuel rail pop out the old injectors. and put the new ones in. Unless your buying new, replace the orings.

 

Same thing. I found some from the junk yard in a v8 explorer is another option. I'm running them no problem very very easy swap

 

Sweet so it doesn't matter what year?

 

What year do you have?

You could also use Dodge Neon injectors, 703s are the last digits of the number.

Run a search for injector. You'll find plenty of info here.

 

88 renix system, any explorer with a v8 is gonna have the yellow stick injectors. Do a Google search u will find more than enough info

 

I have 97 xj 2 dr 4x4 4.0

 

what are some pros and cons about doing the injector swap
i dont want to get worse gas mileage than i already do

 

I'm running injectors from a crown Vic they were a " pocket item" from the junk yard.... not any better MPG but a lot more power great improvement totally worth it

 

I went from 9-10 mpg to upper teens. Of course my injectors were 20+ years old. I cant think of a single con if you do the job right with the right injectors.

 

I grabbed some injectors off of a 90s GT mustang and put them on my 2.5L YJ and they work amazing!! My motor is bored .30 over and has a bigger throttle body on it so the GT injectors boosted it almost back to normal. If your motor is stock it might waste some more gas but lets say you have the 62mm throttle body on your 4.0L it prob wont be a bad idea to try the GT injectors out. I'm gonna try it when i get a bigger throttle body for my Cherokee

 

What pound injector would be best for a stock engine? 19? 24?

 

19 is what u want. 24 is to much unless u got a stroker. I'm running 19 same mpg but runs way better. All I see are pro's with the swap

 

How much are injectors I don't know were at jy is

 

I''m actually the injector vendor, and I sell these injectors for 55shipped with a 30 day warranty or 60shipped with a year.
They come completely cleaned, flow tested & new filters!

And no 24lbs are not too much for a 4.0 search my recent posts, just posted tons of tech in a recent thread!
