itll be easier to just buy a 6 cyl, I think that you have to modify the fender wells, and front end...seeing as how the 6 cyl is 2 cyl longer...

You don't have to modify the fenderwells or front end. The TJ came with both a 4 and 6 from the factory.

It is more an issue of engine mounts, tranny mount, etc. It can be done....if the deal is that good on the 4-cyl..... However, consider the extra cost involved in a swap first, tho, before buying it to save $$$. It could end up costing more to swap than to go with a 6 to start out with.

Yeh, I wouldn't do swaps like that on newer vehicles when other models already came with the 6. Swapping to a V-8 or something is another issue, tho.

However, I noticed in his other post that he decided against the swap, a smart move in my opinion.

V8 swaps are, i my opinion, best suited to trail rigs that don't have to conform to the CARB rules and guidelines. I would love to drop a V8 in a YJ or even my XJ, but I wouldn't want to mess with making it legal.
