2.5 rebuild questions

hey everyone, I just recently bought a 1990 YJ, 2.5 5spd...it had 166k miles on it and had a hole in the front piston....my brother had a 89 yj with the 4 cyl motor...so i had planned freshening up his old motor and dropping that in but when i pulled the head off from it I realized it needed a rebuild.

what i need to know is where is the best place for me to buy a crank kit, piston rings, cam (high perf?), lifters etc.

I am not new to jeeps, i have owned 5 other YJ's and 1 XJ..all have been 6 cylinders..so this is my first encounter with a 4 cyl...I have got 32's on the jeep right now and plan to go larger down the road, will a 4 cyl have sufficient enough power or should i save the money i would spend rebuilding the 4 to put towards an engine swap?

With that size of tire and bigger you're better off going up to a six or 8cyl. You won't have the umph for highway travel.

95 YJ 4 banger
4" RE + 1" body + 1" shackles
31" Super Swamper LTBs
Custom Gun Rack
Custom Rocker panels
