engine swap in a 94 wrangler

i have a 94 YJ, i want to put something a bit... larger in it, the 2.5L is pretty gutless with the 33" tires on it, what engine would be the easiest to put into it? i'd like to get 200+ hp out of it

4.0 stroker, and v8's are closer to 300 hp.

computer and trans are needed, along with wire harness. a 4.0 is around 180 hp as is, with a donor vehicle its a pretty easy swap as swaps go, motor mounts have to be moved.

I'm starting my swap this winter. Can I reuse the old mounts and just move them up or buy 4.0 mounts and weld them in.

I switched a four to a six and built new motor mounts. The four cylinder mounts won't come close to fitting without rework. It was much faster to build them out of tubing and flat stock. Considerable time grinding the complete mount off also. The factory really got carried away welding them solid, no gaps.
