I have a 96 XJ 4.0 HO. I wanted to upgrade to a 99+ intake and since I was at it I would do the injectors and TB as well. I wanted to know if the 784 injector will work on this setup and do I need a 96 TB or a 99+ TB. I also have an aftermarket header on right know and was wondering if there is going to be any fitment issues with the 99+ intake.

 

The intake will bolt up to the head just fine. The TB are all the same size through the years. The 97 and up TB use different sensors so you will need to use your 96 TB. As for the injectors do a search because i believe the 784 are for the 97 and up xj. You will have to extend a few of the vacuum lines for the new intake. If you need more explanation then do a search, there are alot of wright ups out there.

 

I have done my research and could not find anywhere if I need injectors for my 96 wiring harness or for a 99+ intake. Thank you for clearing up my other questions

 

I have a 96 and want to do the 99+ intake I was going to use the 703 injectors from a neon. Everyone says good thing really. I'm not sure if the work on the newer intake tho. Ill look around

 

The injectors are the same size from 91-01. The only difference is the electrical plug. You can use your stock 96 injectors or the neon injectors as i did and they will all bolt in the same.

 

Thanks! I will be out looking tomorrow after work!

 

What kind of power gain are we talking on the intake

 

Not sure someone did a big write up on it. If I find it I will post it just search 99+ intake it shouldn't take you long to run across it

 

Yea I know I was at work and didn't have time figured this thread is up might as well ask
