TJ 6 CYL IN YJ

HOW HARD WOULD IT TO PUT A 2001 TJ 6 CYL INTO A YJ WITH A 4 CYL? I KNOW I WOULD NEED A NEW TRANY (AX15 I THINK) AND A TRANSFER CASE BUT WHAT ELSE WOULD I HAVE TO BUT. WOULD I HAVE TO MAKE ANY BIT MODS FOR IT. WOULD IT USE THE SAME ENGINE MOUNTS. WHAT WOULD I NEED AND HOW MUCH IS? PLEASE HELP ME OUT. ALSO I TOW MY DADS BOAT ALOT AND IT FEELS LIKE IT IS VERY HARD ON THE ENGINE AND THE TRANY. SHOULD IT BE HARD FOR A 4 CYL TO TOW A 20' BOAT OR IS IT JUST ME?

duh.. the 4cyl isnt made for towing..
6cyl maybe.. but you're better off with a larger, heavier vehicle with a longer wheelbase, like a mid-full size suv or pickup..

With my inline 6 4.2 liter engine, I have had no problems towing a 14" motorboat (estimated weight 1000lbs). My Jeep runs with 3.73 gears which helps alot!

If you wish to tow a 20" boat with your Jeep, I would say best bang for your buck would be 4.88 gears and a little extra weight on the front. With cost of installation (if you can't do it yourself), you might be looking around $1000 (someone can confirm).

A used Chevy 2 wheel drive 1970's to early 1980's 1/2ton truck .. might cost you $800 .. I would say get another vehicle just to do the towing.

I agree with Naekid. I towed my boat w/my yj a few times. Short wheelbase and long 2000lb trailer is a very interesting combo when you live in hilly areas. I bouth an '82 chevy heavy 1/2 ton with a limited slip rear, v8, and super granny low gearing. All for $700. It's ugly, but way nicer to tow with. And after I get done refinishing my boat, the truck will get the next treatment.

Fellas, prepare for a good laugh. Until recently, I was towing my 23' 5,000lb boat/trailer with my YJ. The trailer is tandem axle with brakes, or this would even be more ridiculous. It wasn't pretty, but it got the job done....eventually. Recently, I added a Navigator to the fleet so my Jeep is much happier.

As far as the original question, the gear swap would be the easiest way to go. The 4.0 would probably drop right in without too many hitches, but I'm not certain about that. Remember though, Jeeps are not tow vehicles. I would have to agree with the other posts, spend a few hundred duckets getting a old beater pickup.
