4cyl - 6cyl swap - HELP!!

I am looking to purchase a 2003-2006 TJ as a daily driver\beach\ranch vehicle. Most all mods will be minor with safety and economy in mind. That being said, I have not purchased the vehicle yet. I was wondering (and with everyone's expertise to help) if the motor mounts and transmission mounts were the same for 4-cyl as the 6-cyl. Since most every mod will be tame, stock engine and transmissions will suffice. Knowing if upgrading will be less technical than custom mounts will help me decide what my purchase has to be. Any help will be appreciated!

Why not just buy a 6 cyclinder to start with? Would be cheaper and you could just drive it. I would recommend an auto for the beach sand, i have been driving on sand since 1994 and an auto is the way to go.

it is definately not worth this swap, its the same amount of work to do a V8 swap. The you will need the engine, tranny, Transfer case, wiring harness, and computer to make it all work. then you have to make/fabricate/cut off doner jeep - the motor mounts and weld in, you might as well just buy a 6 cyl. to begin with. and for future reference, no the transmission will not bolt up, the xfer case has different spline count, and motor mounts are differnt.

X2.. However if you can't pass on this particular Jeep and your already thinking about a motor swap why not do a Magnum 5.2L or 5.9L?? Basically not much more work. The Jeep 4.0L is a great little engine but if I were swapping that's what I would do..

That's the information I was looking for. I was hoping to be able to get a 4cyl cheap and run it until it quits, stock piling other upgrades, and do the whole swap over at once. I'm now just going with the 6cyl and will piece it together as I go. Thanks everyone!
