Upgrading my injectors

From what cars can I take injectors from for my XJ? I've heard of people using like injectors from Dodge Neons? And pretty much any 90's Ford or Dodge vehicle at that. What do you guys recommend and what works with my Renix 4.0?

Okay. So I'm assuming my engines a renix so do I need to upgrade my fuel rails too? Or can I just do a straight swap out of injectors?

Just injectors. Use new o-rings that you get from the parts store. Put a little motor oil on them before installing.
Have you ever looked at this site? I've used 3 sets of his injectors with excellent success. No guesswork. The price is per set of 6 BTW.
