62mm throttle body

I know what you mean. I'm working up a build sheet for that very thing. The cost is actually pretty reasonable for what you get out of it. What would kill me is the down time. All the research that I've done says that the best way is to do a frame off restoration type build and use a GM engine and transmission. Increased power and possibly gas mileage would be really hard to argue with.
stG58,
The other less talked about engine swap is using a Dodge engine. The good thing about this is there isn't any flim flam needed to make the computer talk to the dash. Now a lot depends on what year TJ you have. I have a 97 so my swap was real easy. I started with a 5.2L Magnum V-8 from a Dodge pickup or Dakota. You can also use the V-8 out of a Jeep Grand Cherokee if you want they are just a little different.
The Ram computer fits in the stock location and you just blend the Jeep & Dodge wiring harness together. The 5.2 I got was a low mileage engine but I could never get it to run right. So I ended up buying a 5.9L V-8 that was pulled by a shop and replaced with a crate engine. When I got the engine I had planned on just rebuilding it but a stroker engine fell into my lap so now I am building a 408ci. To handle all the extra power I had a RE46 auto tranny built. I had a SE model so I was going from a 4 cyl to the V-8 which was nice. If you plan things out you can have the swap done in under a week. There are some good write-ups over on the JeepForum about guys who have done the swap. If you would like more info just drop me a line and I'll try to help where I can.

This is interesting, I didn't know this but now I am going to do my research on this!
 
Chris,
If you wanted to go with a Mopar engine you should look at doing the Hemi swap. Dodge stopped using the Magnum V-8 engines in 2002 so to stay smog legal the only way is with a Hemi swap. They aren't that hard of a swap either with companies like Tera Flex and Novak making kits.

Yes I am currently exploring all my options with Chevy engines, dodge and the 4BT Cummins.

Just trying to determine which one is the easiest to swap in, and most cost effective way to go.

Have not looked at Novak lately but when I did mine they definitely were a GM swap company. They actually we the ones that convinced me go go GM over MOPAR. I originally wanted to do the he I swap but kept getting outbid at auto auctions for any wrecked vehicle with a hemi in it. I paid 5k for a 2012 3/4 ton HD chev truck with 24 k on the clock. Every damn hemi I bid on went for a hell of a lot more.
Nothing against the hemi, but there is a lot more after market support for the GM conversion. 2cents

Stinger,
Not going to argue that there isn't a ton of support for GM swaps. But there are companies out there that support using a Dodge engine too. It is crazy anymore as to what is out there. My engine and tranny was bought at a junk yard so I don't know about trying to buy a complete rig. You can find hemi takeouts on Ebay with the tranny & ECM plus wiring harness for under $4k.
 
Oh the choices I have... The good thing is that since we're moving to Salem I don't have to worry about passing emissions, so it's pretty much whatever swap I want without having to worry about emissions.
 
Chris,
I understand what your saying but I would want to keep my rig smog legal just in case I ever moved again or if where you now live changes and starts doing smog tests. Of course it is your rig and you can do as you want.

My intention is to keep it smog legal in the long run. I just mean in the short term I'll have time to get things figured out.

I realize that this is an old post, but curiosity has gotten the better of me. Chris, did you end up doing a swap?

B

No V8 swap yet. It will happen in time, but right now I've got so many little things to deal with around the house.
