Switching engines for a YJ

Let me just start off by saying, I do not know alot about cars/jeeps but I have a small idea.

I am looking to switch out the 2.5L I4 engine in my '90 YJ for a newer engine from a TJ. I need advice, and alot of it. I was planning on just buying a junked TJ and switching out the parts. What type of converting parts/kits would be necessary to do this? The work will most likely be done by my father and I (but mostly my dad). So I need a simple, yet efficeint way of doing this.

Any tidbits and advice would be appreciated!! Currently it's lifted 4" and I am looking to put 33's on it. So I need more power. This is my daily driver and off-roading vehicle.
