Joel's multipurpose XJ build (rocks/boulevard)

Hi y’all.

I’m SoCal resident and professional engineer but I’m still a little new to the world of Jeeps in general and XJ’s in particular… That’s just my way of asking forgiveness up front if some of this build comes across intelligent and some of it is pretty ignorant. I’ve been lurking on here for a while now and I’ve been reading a lot. Figured it was time to get a thread started... I would have put this into advanced fab and engineering but as a newbie apparently I don't have rights yet, we'll see if I'm worthy after this gets going.

Step one: Find a vehicle that I can use to:
-Serve as back-up vehicle when my daily is under the knife
-Carry 4 people in relative comfort (family man)
-Take camping / throw a mtn bike in the back
-Haul a car trailer in a pinch
-Build some cool *ish and take it wheeling, but keep it looking nice enough to be respectable
-Find something interesting so I won’t regret selling my motorcycle (again family man)

Winner: 1999 XJ, black on black on black…

Paid a little more than the typical going rate, but it was built very close to exactly what I wanted, 96+ meant it had the slightly more modern styling, and it was in stellar condition inside and out. I was also glad it’d had a lot of routine service done because I have enough projects that I didn’t feel like chasing oil leaks and the like. Finally, from what I read, ‘99 is the money year to have: something about head cracking issues on the 00/01s due to different castings with a coil on plug setup?

Dig the Rigid bumpers:

Now that’s a clean interior!

Obligatory engine bay and suspension shots:

Bought the car in Iowa on the return from a business trip and drove it straight out to Cali. I almost went straight through and ended up driving 26 hours in a 30 hour period, slept in the back for a couple hours (and froze my tail off somewhere in the Rockies.)

13 mpg on the freeway, yikes, wonder what it gets in the rocks. All that for a lousy 190 hp? Ugh… If the I-6 ever lets go I’m yanking that lump and finding an alum v8. Mine has some miles so it’s a real possibility, unfortunately the more I read the harder it looks to kill these things.

Given the build specs above anyone have any obvious recommendations?

FWIW I’m already a big fan of LS1’s. Here’s the daily driver:

A last note:

If anyone wads up a built XJ and has a matching set of hardcore axles to sell I’m interested, particularly if you’re also in SoCal. Presently debating whether I lightly polish the dana 30 turd, or just save the money for a d60/d60 setup that I could throw some HP at someday.

Bought the Jeep about a year and a half ago. All the stuff I’ve done since comes next…
