4cylinder swap to 6 cylinder Is it worth the trouble???

Ok so my parents have a 1997 Wrangler 4-cylinder 5-speed base model that Iíve been given / purchased for a very small price (its been in the family for 12 years). I also have a donor fully running 1998 Jeep Cherokee with the 6-cylinder motor.

What type of headache would I be in for if I decided to pull the anemic 4cyl out and replace it with the 6cyl with 15k on a new rebuild motor???

Iím not looking to have the Jeep inactive or unusable for long I was hoping that itís a direct bolt in type swap.

Or is it even worth the trouble, as I will be selling off my other cars and only driving this one for the next year or so.

Other than the motor mounts is a direct fit. You got to cut and weld those back in right spot.
You have 4.10 gears with a 5 speed. So consider that when installing the 6. You will not be able to use the 5speed from the 4 banger. I would install the cherokee trans either if its auto or 5 speed. Wiring can be as simple as splicing in 2 more injectors or ordering a OEM wiring harness from junked TJ that had 6 stock..
Worth it money and time wise, no. Worth it for a learning experience yes. Worth it to get the cherokee auto, yes. Time wise you will have to be on a schedule to do it all in a weekend. Drive shafts will need to be cut and adjusted for the new length.
READ there are a million post on this. Been done to point nothing you will run across has not been worked out and overcome.

For the amount of time and labor that goes into a engine swap, a v8 is pretty similar in cost and time.

That said, you're kinda stuck with an automatic with a v8 unless you like a real challenge.
