Want to BUILD a Jeep

Have a 2002 TJ that I love, but the frame is rotting out. Looking to stay with the TJ, and was considering buying a cheap donor with a good frame, and swapping in a V8. (plus lifts, etc.). Had some questions though:


1. Is a amanual or auto easier?
2. Does it matter if donor is a 2.5 or a 4.0?
3. Best options for a V8 (not looking to spend Hemi $)
4. Will I also need a new tranny (and best options there?


Thanks

1. I'd say it depends on what the Jeep originally is. Easiest is to keep an auto an auto or keep a stick a stick.

2. Doesn't matter for a frame donor.

3. 5.3/6.0 Chevy or 5.9 Dodge.

4. Most likely. Best to use the tranny from the engine donor.

I would say the magnum 5.2l or 5.9l swap would be the most cost affective option. The motors are cheap. a majority of the wiring does not change. Factory gauges can be made to work. As far as the auto or Manual goes I think it comes down to preference. I started with an 2.5l auto and now have a 5.9l manual.

I just swapped in a chevy 5.3l into my LJR. Was very easy using Daves motor mounts , stand alone harness etc..Had to modify my cross member as everything moved up 2" but that was the worst of it.

Using the NSG370/241OR combo with a Novak adapter plate. Love a manual V8. Can't complain at all. Running stock gauges.

My cost was about $5800 cad (minus $1000 for my old 4l I sold and $800 for having it uninsured, saved)

Don't mind the wicked black tape mod in my pic I have not got around to "blacking" out the check gauge/ engine light bulbs.

Magnum 5.2/5.9 swap is the easiest and can be done extremely cheap if you find an entire donor vehicle, and then part out the donor after you pull the engine/trans/whatever else you need, AND if you do all your own work. People are typically most afraid of the wiring harness portion, but again, with all the info out there and all the FSM's available online, its extremely simple.

Well you have a one of a kind Hemi jeep now. Seems like these LS swaps are popping up everywhere after my build. I think people here are thinking, "if TJnBC can do it, I CAN! " hahah, as I had never done a motor swap before.

I learned a lot from this swap doing 90% of it on my own (welds by others), all for the good. Was happy it worked out as inexpensive as it did, because I was warned of $10k for swaps easily.

Best advice I can give.
Sell that rust bucket and buy something with ZERO rust..


PLENTY of good jeeps that have a lot of good mods done to them also out there. Unless you just enjoy the process of doing a V8 swap... There are lots of those out there too for a LOT less money turn key ready to go. Also I dont play that "if you dont build it yourself you will not know how to work on it" well with the advent of internet everything is at your finger tips on repairing even the most complicated issues...
