Is this possible??

I was thinking about trying to put an old straight 6 with carbs in my ZJ....possible without a lot of modifications?

Anything is possible. But my question is why? Why would you want to go backwards?

If you want a straight 6, just a a ZJ that already has one.

I knew I would get that question...

I have my reasons that I will keep to myself for now, but the ZJ I have is in great shape and has a 5.2L motor. I'm looking to get a bit better MPG and can't find a good one around here for a reasonable price. So, I thought I could just modify the one I have.

If you want a 6 that bad, why not swap in one with EFI, out of another ZJ? There really isn't any reason to go from MPI to a carb setup....

Difference in gas mileage is barely noticeable on a ZJ 4.0 and a ZJ 5.2. Not sure how much the carb type (probably not the 4.0 HO) would save you though.

It would save nothing. You will get worse mileage with a carb.

No way I can see that you'd get better mileage from a carb. Everything went EFI for a reason.

I guess at the very least it would be interesting...but your talking about basically every computer system not applying in this setup...totally replace fuel system for one thing. And you'll never pass emissions ever again lol.

If you're going to do that...throw in one of the old powerhouse V8s or something lol

Less power, worse economy, worse cold weather starting, difficult to make the interior computers happy...not really a decent idea. Even a carb v8 isn't a very good idea.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

You will never get better mileage with a carb versus efi

Plus, the switch from a V8 to an I6 involves a ton of stuff. You'd likely spend as much on that swap as just selling the ZJ with an 8 and getting a ZJ with a 6

I was pleasantly surprised to discover this when I started driving my 5.2

Plus carbs give problems on the hills and offroad in general.
