Diesel options in a Jeep:

1) SD33T - out of 80 scout - lower power/torque - right gears etc 20/24
2) SD33 - out of cj-10 or earlier scout - " - got 16 - 19 in a cj-10a
3) 6.2L GM - did one in a '91 GW - worked ok - 16/24 - I'd do it again
4) 5.7L GM - if you can find a targetmaster engine might be ok. I would avoid
5) 4.3L GM - don't know much about these, had good rep at the time... I would avoid
6) 6.5L TD GM - plenty of power options, but I'd avoid, not economical, go with a 6.2 rather
7) Mercedes 3.0L TD - I-5 - '82-'84 - fairly economical, enough power,  (OM617) - kit below
8) Mercedes 3.0L (TD) - I-6 - '86-'89 - not as economical, powerful, don't overheat head issues, kit below should work
9) Mercedes 2.5L (TD) - I-5 - '87-92? - economical, powerful - not sure if the kit below would work - might
10) Mercedes 2.4L n/a - I-4 - '82-86? - economical, underpowered - not sure if the kit below would work - might
11) Cummins 6BT - heavy, noisy, tall - has been done - I don't want to drive a freight train, weight biggest issue
12) Cummins 4BT - heavy, noisy, tall - has been done - I don't want to drive a freight train, weight biggest issue
13) VW TDI - this is a 1.9L four cylinder... it looks more like a toaster than a powerplant - expensive to buy, 
	rubber band (80-100k), egr will clog up the intake every (40-60k), can be very economical.

TDI in a jeep?

http://blogs.jpmagazine.com/6667601/editorials/easy-jeep-vw-tdi-diesel-swap/index.html

In stock form the VW TDI engine pumps out 100 horsepower and 180 lb-ft of torque, but is said to 
be easily cranked up to an impressive 165 horsepower and 280 lb-ft of torque with a simple power flash 
(The factory Jeep 2.5L puts out 123hp and 145 lb-ft). The 1.9L TDI weighs in at a svelte 265 pounds 
compared to the Jeep 2.5L at 325 pounds. It's 55 pounds lighter than the four cylinder! In the Jetta 
the 1.9L gets up to 47mpg, in a Jeep it will likely get slightly fewer mpgs because of the Jeeps added 
weight and increased wind resistance but it should easily hit the 30-40 mpg range with normal use.

VW engineers confirmed that the 1.9L oiling system was designed to handle a 1G environment allowing 
for 45-degree angles in all directions. An optional deep oil pan may be made available for even more extreme use.
