Not to mention the engine is lighter, has more power, gets better fuel economy, more potential to mod, sounds better, etc, etc...
Not a cheap swap though. On a budget I would have to go with the 5.2/5.9 magnum.

The exhaust for the V8 will be custom.
Transmission behind the V8 will often require a custom crossmember.
V8 will sometimes need gauges other than stock TJ gauges.

|clintrivera||I'm curious what hassles a V8 swap has over a I6 swap. If you are mechanically inclined enough to do a I6 swap, a V8 swap is not much harder if harder at all.|

|nic012cinko||yeah im looking to do this also, but i dont want to deal with the hassles of a V8. I just want to do the 4.0. Let me know if you find anything out! i would be happy to help you also if i find anything worth while.|

I just finished my swap of a 2002 4.0 into my 2001 TJ. I even reused the old mounts I cut from the frame.

I did it, as did many others on here.. It is as easy as going to a V8, but much cheaper..
I bought a wrecked TJ with I6 and swapped all the parts.. Other than welding new motor mounts on, it was all plug and play..
After selling the old parts and selling the rest of the wrecked TJ I broke even or actually made a few $$...
I could not be happier.. 4.10 gears from 4cyl, I6 power and torque.. Even with 35" tires it ran and has more than enough power..

|2000TJMan||I figured it would be easier to buy one with an I6 just checking though. Thanks.|
