Go here http://www.ifsja.org/forums/vb/showthread.php?t=113929 it might help

Then for a little more info on the little nissan SD33T
check out http://www.binderplanet.com/forums/forumdisplay.php?f=5


For all the crap IH gets about doing things differently they pushed the cutting edge a few times integrating a turbo diesel into thier line while other manufacturers were just begining to look at adding NA diesels into thiers. the SD33T was ahead of its time and lacked the necessary torque in true IH fashion "underpower limit the warranty claims" fashion. a built 4bt or even a stock 4bt will out perform the SD33T but the SD33T will hold its own

Cumins 4 or 6bt is the only way to go. 6bt is better but a lot of extra work. Prices at the moment
Are way down for these with the 6.2 being given away for scap prices

i found a sd33t, the engine is there, i'm just missing the rest of the drivetrain.

i think i could pump some more power out of that motor with some extra boost, bigger turbo, intercooler etc.

i'm going to see how much i can get out of the 401 in my jeep right now. i've just got to get the hood open and get it running.

SD33 is a great light engine, I'm installing a 6.2 as I tend to get them for free or close there too... I also considered a Perkens 354, I have an XJ to recieve an OM617, tuned up it'll do an FSJ just as well at the 140hp SMOGged out 360

OM617 would be interesting. I think there is a company making an adapter for it for GM transmissions now.

the only one I have seen is for one of the overdrive autos at over a grand in price! From what I have read they have been advertising for a year but haven't shipped the first one yet

Check out the Isuzu/GM engine in the NPR series light commercial trucks. Versions with power @ 135, 175, and 205 hp. Prices have dropped dramatically, availability is good, including parts. See JeepinPete's thread regarding his swap. No brainer, especially for 2wd.

the 6.2L diesel makes 135hp@3,600rpm and the 6.5-T makes 190hp@3,400rpm, trust me if you plan on towing you'll need short tires n 4.10's or 4.56's & 4.88's . . .

Remember GM gears them to cruise 2,400-2,600rpm, so if you lug it down to 2,000-2,200 rpm it fall flat on its face towing heavy . . .

My 6.5-T is all factory geared and tired it run's 65mph@2,500rpm, it get really sluggish under a 4,500lb load.

i put 1,500lbs in the bed and hitch 3,000lbs behind it and my 6.5-T was very sluggish and doggy.

Towing 6,000lbs was crazy slow it wouldn't really pull for crap lots of 2nd gear hill climbs.

I can't imagine the 6.2L would be any better but it seem's to be more reliable the 94+ 6.5-T's have the electronic Injection pump aka drive by wire system they have boat loads of reliability issues . . .

94+ 6.5-T i recommend 4.10's with 32's n smaller tires for a driver / light towing i'd run 4.56's or 4.88's with 32-34" tires for a towing rig over sized tires of 35" + 5.13's

A buddy of mine laughed at me but few months later is K2500 on 38's had set of 5.38's installed and he loves it

Yes, for a grand I could do the entire swap from pick-n-pull for less than their adapter, assuming I gotta buy 2 engines

GM TH400s are a dime a dozen, just takes a little dirty work to get the output shaft on it

Very true, but it's an economy engine, I have a duramax and a 6.9 for that kind of work, and plans to build an F350 with a DT360, My two cents? If you are towing with an old diesel it's gotta have a standard transmission with lotsa gears, I doubt I'll ever tow more than a ton or two with the Cherokee, mostly just drive it around.

Go with a LB7 Duramax 6.6L. And no, I'm not biased due to the fact that I have one for sale that needs a head job & a new gasket

If you're talking about 4x4 Labs and they finally have it worked out please PM cause after years of constant emails all I ever get from them is "we're workin on it"

Correct that's why I posted "GM" th400 and not AMC 400

Pretty much any and all or rather Most of GM's transmissions will bolt to the 6.2/6.5's . . .

I just think swapping a 6.2/6.5 into some thing else is rather pointless, when other more powerful options can be had for less cost . . .

But i will you guy's that much I HATE the 6.5 lousy power piss poor reliability, but the one pro to it is they get 19mpg CTY & 21mpg HWY in K2500 with 4.10's . . .

3/4 ton 4 wheel drive with 4.10's = 19-21mpg other that i simply hate them

CON's:
1. break down often.

2. don't have much power.

3. cost a lot to fix.

4. Limited up grade ability.

PRO's:
1. Can be bought cheap.

2. Awesome fuel mileage.

it was comments like this that originally got me into diesels. i see claims of 19 to 30 mpg out of diesel engies. my favorites are the guys that claim to get 20mpg while towing loaded trailers

my experiences are very different. my 4wd C&C crewcab chevy with a heavy flatbed has a n/a 6.2/rebuilt 700r and 4.10 gears,and very short tires. it weighs about 7000 lbs.

back before the introduction of ULSD if i babied the crap out of it(readut accelerated by kids on bikes ) i could get about 18/19 mpg. since ULSD with the same ultra conservative driving style,it now gets 15/16.

believe it or not i have towed with it. pulled my scout to the trails a couple of times-75ish miles each way,stop/start thru towns and some good grades and i had my foot ont he floor 95% of the time. towing it got about 8mpg.

comparatively my 96 4wd dually ext cab dodge gets about the same mileage round town-15/16. best highway mielage was 23 with a pair of d70s in the bed,and kept the speed at 55. towing my 36 foot gooseneck with 2 jeeps on it to the same trails it gets 9/10. of course thats easily twice the load as the small bumperpull trailer with 1 rig on it. towing smaller trailers i get anywhere from 12-16 mpg depending onthe size,and the route.

my whole point here is that it takes a certain amount of power/energy to move a relatively unaerodynamic mass down the highway at whatever speeds.

i would not have high hopes for getting 20+ mpg in a FSJ with a small underpowered turbodiesel. even with bigger,more powerful TDs to get good mileage youll have to keep your foot out of it and your cruising speeds slow.

having said all that, i think the 4bt is the best choice for a FSJ thats purpose is mainly DD suties,and maybe some mild towing.
