I have a stock ’93 XJ 2.5L. I am not a hardcore wheeler. I’m interested in building my XJ into a hunting & fishing rig that’ll handle mild-to-medium difficulty offroading and trails while also being comfortable to drive on the highway. No extreme rock crawling here. The XJ is also my winter DD.
In addition to these would include basic armor/skid plates, etc., and also recovery gear. I’ve considered aftermarket bumpers & grill guards but I’m thinking that they are unnecessary for my purposes and that the weight of them would hit my MPG too much. That’s the other thing, I’m happy with the MPG of my four-banger and I want to keep that as high as possible.
The idea behind the 2” to 3” OME lift was to give the XJ a suspension that would help get over the type of obstacles I’ll be facing but also be smooth on pavement. Kind of a best of both worlds thing. I’ve read the sticky on modding/wheeling advice and so I’ve been taking the Jeep out in it’s current form and seeing what I like and what I would like to change, and this list is what I have come up with. I know these are expensive mods, but I'm willing to spend the money to do it right the first time and have the best quality.
What do you think? I’m open to criticism and suggestions. Am I missing something?
If you plan to get bigger tires with your lift add gears to the list. Especially since you're getting full case lockers anyway might as well do them both at once.
What MPG do you get with the 2.5? FWIW I'd still look into an easy/cheap swap, MPG may not change much, especially once you lift and the 2.5 will be trying to work harder.

Do I need bigger tires? I was considering staying with stock rims and 235s. I should have 4.10 gears since that is what most of the 2.5's came with. Would you still recommend re-gearing?

I'm getting about 19-20 on the highway and 16-17 in town. I live in a hilly area so I've been content with that. I know those numbers probably aren't much different from the 4.0L but it's better than my pickup so I haven't complained too much. I was under the impression that there was no such thing as an "easy" or "cheap" engine swap... Or am I wrong about that?
I was hoping that the 2.5 could handle a mere 2-3" lift, or am I wrong about that too?

You're right. I was assuming that a 4.0 would be an almost direct swap. Just looked at a couple other threads on the subject, turns out I was mistaken.

here is what mine looked like with 235s and 3" lift. I think they look too small personally but it's all a matter of opinion.
The 2.5l will struggle bad as soon as you start to add weight and big tires.
If you're planning on doing full case lockers I would regear to 4.88s at the same time. This will wake that little 4cyl up, but seriously knock down your top end. Probably wouldn't be very good on the highway.

JMHO, that engine will always be the weakest link until it tosses a rod, might want to sell it and build something else. You could also just keep your current ride and use it for parts.
Thanks for the pic for reference! IMO it looks good.

Do you think the 2.5L will still struggle if I only do the lift and add some armor? Leave wheels stock? How much weight do lockers add?

What makes you say that? Not arguing, just trying to learn. I had thought the 2.5L was pretty reliable.

no problem. And the 2.5 just doesn't have the power I think is why he says it's the weakest link. I think there's a guy on here outlaw something stroking a 2.5. Neat idea if you ask me. Armor can add a lot of weight depending on what you add and I know my locker didn't really add any weight at all, but I have an auto locker.
Why would you lift if if you don't have intentions of adding bigger tires?
Mainly for ride quality and to be able clear rocks easier. The trails I'm on tend to be rocky so it'd be nice to have just a little more clearance. I have read that OME lifts improve ride quality both on and off road. The stiff ride is probably my biggest complaint with my XJ.

bigger tires add even more clearance. And even if you lift but you don't add bigger tires the axles are the same height off the ground and can get caught up.

AH! My Jeep newbieness has flared up. I should have realized this but it just didn't register in my brain.
Well, what would be my best options? I want something that'll work for my basic offroad needs while still comfortable on the highway and that gets the best mileage a Jeep can get. And I want to be unconventional and stick with the 2.5L. I know, I know. I just like to be different. Do I just leave it stock?
