5.3 swap in '97 TJ

Ok. So I have a 5.3 Chevrolet motor. No tranny, or anything else.

I have a '97 TJ with a 5 speed tranny and a 2.5 4 cy.

What else do I need for this swap to work? Will I need a Chevrolet tranny, and transfer case?

Thank you!

It's all custom, so you need everything. Wiring, gauges, drivelines, exhaust, dana 44 or Ford 8.8 rear, probably a radiator, all the emissions stuff. etc

Also, you don't want to put a V8 in front of an AX5

Ok. So I know I don't have to have a Ford rear end for a Chevrolet 5.3. I also know that I don't need to rewire everything, and change all my driveshafts whatnot. And I know i can use the same radiator as long as it doesn't overheat, which could be possible.

So back to it. I figured a transmission was a must, and most likely regearing the rear end. Can I use the Jeep transfer case? Or will it not hold up?

The 5.3 is supposed to be out of a '93 Sierra, so it's not a whole brand new computer setup.

I don't figure it'll be dirt cheap, but I don't plan on trying to drop a 6.0 out of a 2014 Escalade.

They make harness adapters so you can use both the tj and Chevy computer. Now you have to find one

jeep radiator won't work outlets are wrong you will need to do some rewiring driveshafts probably need lengthened or shortened on the bright side the transfer case will work just needs adapting in short this is a huge undertaking do lots of research.

Thanks for the replies, guys. I know I'm not going to just drop it in tomorrow, but it's nice knowing that some things are interchangeable and some aren't. I just was curious about the basics before I start diving into the details.

An big project

It will give you a real pride in ownership and a very nice father son project but

It will likely cost 3 or more times then you think and take 3to 5 times as long

It will have more power but may never pass emissions

It will likely lower the vehicle resale value but no matter if you plan to keep it

Swaps were much easier to accomplish before the OBD emissions and assoc rules so if I wanted a v8 I would go cj or yj not tj

Don't know if someone responded about the rear axle before, but the reason you want the Ford 8.8 is because you can mount it right up after changing the leaf spring mounts to coil mounts. It fits the rear end of the wrangler nicely aside from having a different suspension mount

And to do the swap you don't "have" to do a lot of things. But if you want longevity in the swap, the entire driveline will need to be beefed up. The parts you leave stock will likely just end up breaking under stress after a little while
