Yj engine swap?

Hey guys, I have a 95 yj with a 2.5 that needs work. Should I rebuild the 2.5 and regear or just pull it and go with a 4.0? I want more power but it will still be my daily driver and I don't want to lose any top end since it doesn't have much as is. Thanks.

like saying you want a rifle.... From a 22 to a big bore 445 super mag. Need to know what you going to do 90% of time and build to that. If the 2.5 in jeep is working for the most part, but it is in poor shape, a rebuild will bring back a good bit of power.
Its super easy to fix what you got and get it near perfect, than to swap to any thing.
Tell us what you want from jeep, tire size, trail time, hwy time and FUNDS & skill level.

If the 2.5 needs rebuilt i would do the i6 swap. As long as you have a welder and some know how you shouldn't have a problem. You can a used i6 and ax 15 for around 500$, lot cheaper then a rebuild.

It's mostly a commuter. I hit the trails fairly regularly but nothing crazy. Mostly just mud and some hills. Stock tires for now but it fits 31s and I'd like to go back to them. I don't think there's anything serious wrong with the engine just several little things due to lack of maintenance. One thing that scares me is a coolant leak from the rear of the block that I can't find. Is there a freeze plug back there? I'm pretty novice to all this but I have a good group mechanically inclined people to help with the work when figure out what I'm gonna do.

swap a good running 2.5 for the the existing one.quick swap and it will be cost effective if cost is a issue.couple days and your done.a six or eight cyl swap will be engine trans, weld in engine mounts .drive line work ,then wirring and final tweeking the set up.if your ability is limited with tool access and a spot to work you maybe down for weeks completeing the swap.start simple IMO.
