Hey Guys,

I haven't read all 32 pages of this thread but I do have a question, I eventually want to go fuel injection on my 73 -5 but I only have a single barrel carter carb, do I need to have a two barrel intake to put the 4.3L fuel injection on my Jeep?

Thanks
Grant

Yes you do have to swap the intake. In the grand scheme of things, that's a minor task.

I'm more worried about finding the intake honestly

You can use any 2bbl manifold from '77 (I think that's the first yr of the 2bbl) all the way to the '90 Wranglers. Any '81 and up intake will also require the '81 and up exhaust manifold. AMC cars are also a source.

I have a 1983 2bbl intake and exhaust manifold. Pm me if you're interested.

Hey Guys,

I tried searching through this thread but didn't see this answered. Turns out I don't have a 258/4.2L, I have a 232/3.8L, with the 4.3L TBI swap still work as long as I get the 2BBL intake and exhaust right?

Thanks
Grant

Yeah, it will still work. You may have to tune it a bit more to get optimal power due to the displacement difference, but it will definitely still work. Based on what I read on some other sites, the only difference between the two is a shorter stroke.

On the same topic, I would highly recommend looking into the EBL Flash system for tuning. It eliminates the tricky chip swapping and EEPROM flashing. I used it on my 258 and was more than satisfied. I moved it to my new 360, and am thankful for the ease of flashing! Much tuning is in my future.

Is there a more updated thread on how to do all of this? Or maybe a better parts list?

CSP I don't know if you will see this but you were talking about a pre cut harness where do you find that?

An updated thread or better parts list? This thread either has all of the info needed or links to places that do like the other reply I quoted. You are going to have to do some research on your own just like everybody else does who does this via DIY. That binderplanet link has threads in it with info specifically listing what's needed.

I bought a pre terminated harness from Affordable Fuel Injection as part of their DIY setup to save some time. I don't know if they sell the harness alone.

I just posted a collection of parts for a 258 EFI conversion on the classifieds. It's not complete, but it's a good start. (Under Misc. Jeep Parts)

I have a 79CJ5 with an AMC 360 in it. I live in the desert and the damn think keeps vapor locking. It gets warm and if I stop accelerating it dies. I have been told that the issue is most likely the ethanol in the gasoline nowadays. Same guy told me that putting an electronic fuel pump should solve my issue. That got me looking into fuel injecting it. I had it die on me doing a hill climb at altitude and was told that Fuel injection would solve that problem. I'm fairly new to this type of stuff, but I consider myself pretty handy with a wrench. I've done plenty or R&R stuff like fuel pumps, axles, valve cover gaskets, ect. So I don't think that this type of a project should be out of my abilities. (but I've been wrong before as my wife loves to point out).
Does anyone have any recommendations on how to go about doing these two things?

If you aren't a fan of junkyards and used parts, there are several companies that make FI kits for your engine. Howell, Affordable, and MSD to name a few.

Aww Matt, Used parts need love to.

If going new, I vote for Hamilton Fuel Injection. Bill is the best, he helps all.
