I love my troopy (2H engine), but no turbo at altitude makes it more of a pig than it usually is. I don't really care, I just go slow. When I rebuild the engine someday, I'll probably add a turbo. Or if I win the lottery, swap out a 1HD-T.
My wife insisted on our HDJ81 (gotta love my woman!) because she loves the 80 we've had for a while and wanted the same thing. SHE was the one that wanted the RHD diesel (again, love her). I tried talking her into a 100 or lower milage 80... nothin doin. We've had it comp tested (came out great!) and it's getting the BEBs, valve adj, timing belt, etc currently done ($$). The brakes need love, the rear pinion seal is gone, a front end service is due and maybe new birfields, and the alternator might be shot ($$$). And that's just the obvious stuff. The 1HD-T engine is awesome at altitude, but not as strong or peppy as the gas 1FZ-FE. But we got interested in diesels when gas was $5/gal. The 1HD-T gets 17mpg while the gas gets 12mpg (my PU with the tiny 22RE gets 19-20mpg).
Harrumph, Harrumph! All of our LCs have cost us a bunch of money, more than ever anticipated! On our third project now and kinda used to it. My pickup is super cheap to keep rolling: alternators cost $120 for the PU, $225 for the FZJ80, and $635 for the HDJ81! If I didn't have a cool wife, we'd be driving normal boring cars... and my truck.
Alternators are easy to rebuild. Dropping $635 for a stock 12 volt 80amp alternator is insanity.
