at 120k, you can most likely expect to spend almost $1k on new rockers and ARP head studs (if the head gasket isn't already leaking bad). Then another $1k on a new turbo. You don't even want to pay someone to do either of these, as the labor is really high, so if you can't do it yourself, then it may be a bad choice.
That $2k or more should cover the big ticket items, but I would expect to spend $3k+ on parts for everything that is worn out (bushings, shocks, springs), and then at least that much on the labor if you have to pay for it. That will produce a long term, reliable jeep. I put about $4k into mine, and it already had about $1k of goods installed from the previous owner.
Buy one from a Lost member that has already installed the necessary mods is the smartest route, or get a junker for cheap and restore it. Hopefully this saves your wallet

Mountainman,
I'm not attempting to start a flame war, when I say the following:
Your post may be somewhat misleading. I say this as my 2006 CRD has 170K miles on it.
-Original Head Bolts
-Original Turbo
-Original head gasket, and no leaks
-Original rockers with no malfunction
My $.02 is that if you drive it "Diesel Correctly" (slow warm-up, don't drive it like a gasser (no throttle mashing), proper cool-down), you'll go a lot farther on the original setup.
Or maybe I just got absurdly lucky with my '06 Sport.
