86jeep Posted January 29, 2012 Share Posted January 29, 2012 2.5 fuel-injection to 350fuel-injection. Since my 2.5 is FI when i switch to 350. I wonder how hard it would be to keep the FI. I got a 91 burb that is throttle body. what is ya opinion on that topic. I know the 4cy fuel pump might not carry enough fuel. And i know i would need the computer from the burb . I got my 78fsj narrow track passger side drop Axel. My motor will be a 91 burb motor. Tranny And Tcase from the 91 burb. Thanks Link to comment Share on other sites More sharing options...

pwrliftin Posted February 2, 2012 Share Posted February 2, 2012 I've been doin a lot of research on this because I will be doing the swap this summer. The best thing I've found is to run a carb. I've talked to a few people that said making a stand-a-lone setup wouldn't be to hard, but I really don't know anything about wiring or fuel injection.

pwrliftin Posted February 2, 2012 Share Posted February 2, 2012 http://www.novak-adapt.com/knowledge/xj_swap.htm Doesn't talk about keeping the old fuel injection, but about halfway down there is a section on TBI and FI. Whole page is very usefull! Link to comment Share on other sites More sharing options...
neohic Posted February 2, 2012 Share Posted February 2, 2012 I don't recall the website off hand, but a while back I found a ton of information on an International forum that centered around using GM components to add fuel injection to their V8 Scouts. I went a similar route that I needed to build a stand alone fuel injection harness for my friends '90 YJ using GM 4.3 parts. As far as I know, the wiring is almost identical between and 4.3 and the 350s for TBI. Very easy to pick apart a harness down to what you need. I'll do some digging tonight to see if I still have the links. Edit: This Link hads a ton of information for adapting the wiring and parts to an IH motor. Again, I used much of it just for the wiring diagrams. Link to comment Share on other sites More sharing options...
