I saw a Geo Tracker swap and they maxed out the RPM's at only 53mph.  Way too slow for here.

couldn't find the specs on Di but the 2203-M is 48HP@2700 rpm and 106ftlb around 1600rpm, is the Di much more powerful that that? (i think the M is n/a and Di looks turbo unless that was an addon) seems a  bit low in power/torque and for sure low revs as well.

[stan98tj]

seems to move along well. Wonder if this is a good alternative to the VW swap. Although the TDI is 1.9l, HPA claims around 300ft lb torque and around 200hp with plenty of torque avail at the lower rpms. The VW is small, however.

[sharpxmen]

when i looked for the 2200Di specs i found the 3300Di listed at 98HP around same rpm (3.3liter turbo), torque is probably about 200ftlbs, i think this one would be a better alternative, however still with low rpm. BSFC was listed at about 0.4 to 0.43 for the whole range (very flat curve).

The flat curve and low RPM's is normal for diesels though.  The Cummins 3.9L performance peaks at only 2300rpm.

yeah, but then you need to change the r&p to get anywhere on the hwy which kinda defeats the purpose (will kill your torque). the Cummings has more torque to spare compared to the Kubota (265ftlb@1600rpm), mind you the Kubota is a utility type diesel (generators and utility vehicles with 20mph top speed) so for the purpose is probably great, not sure if can be said the same when installing it in a street vehicle, maybe with a granny 1st transmission would work (but i know nothing about it so i'm just going by the specs i saw). I think the VW is the better choice.

Even with the VW, they don't recommend gearing too low.  IIRC, their Jeep had 4.56's.

IF I ever go Diesel, I would just go with a Toyota 1KD-FTV engine.

First appearing in 2000, the 1KD-FTV is one of the newest engines built by Toyota.
 
The 1KD-FTV is a 3.0L (2982cc) straight-4 common rail diesel engine with a variable geometry turbocharger and Intercooler. It has 16 valves and a DOHC (double overhead camshaft) design. Bore is 96 mm and stroke is 103 mm. It generates 170 hp (127 kW) at 3400 rpm, and 260 lbf·ft (352 N·m) of torque at 1800-3400 rpm. Redline of this engine is at 4200 RPM. Compression ratio is 17.9:1.
 
This engine uses Toyota's D-4D Common Rail fuel injection technology operating at ultra high pressures of up to 135 mpa (1350 bar or about 19,580 psi) which is about 8 times more than the pressure of conventional fuel injection systems within a "common rail" that feeds the injectors on all four cylinders. This is combined with a 32-bit ECU which controls fuel quantity, valve-timing, and boost pressure at different engine parameters resulting in best fuel economy and also full utilization of power during acceleration. Pilot injection is also utilized by the common rail fuel system to smooth engine operation. Small amounts of fuel are introduced into the combustion chamber prior to the main injection event, reducing lag time and promoting more continuous and complete combustion. Exterior and interior engine noise is also reduced.
 
The 1KD engine produces 17% more power with 11% less fuel consumption than its predecessor, the 1KZ engine.
 
This engine was first used in Toyota Land Cruiser Prado, 3rd Generation Hilux Surf and now used in the Toyota Fortuner, Hiace and Toyota Hilux.
 
It presents a big issue with the injectors which is still pending to be solved. In Spain, they change the injectors within the first 7 seven years after buy, but still no solution is provided by the manufacturer.  Due to the non availability of Low Sulphur Diesel to much of the world, injector failure is very common with this engine.

I have to say that HiLux and Fortuners are very comon around here, so the engine is easy to get.  Also, I have a Fortuner myself, and have yet to experience any problems with the injectors (of course, I don't fill up at just any gas station I find out in the boonies; I try to stick to brand names, which have better fuel than stations you may find out while trail riding - keep in mind diesel is as common as gasoline in Central America)

I think it would be a smart move to go with a Toyota.  They are everywhere.  Nissan's come in second and Mitsubishi in 3rd.  Too bad we can't get them here in the US.  Well, you can but they're not legal.  Then parts might be harder to find since you would have to special order a lot of it.

This is why you see a lot of weird diesels used here.  The 4BT is a fixed diesel engine.  Meaning it's designed for generators or mixers.  It's nice to see people get creative with other engines though.  The 4BT isn't the be all end all that some make it out to be.

subaru is also a good candidate i think
2.0L intercooled turbodiesel
147HP@3600rpm
258ftlbs@1800rpm

Subaru isn't really known for their diesels though.  Might also be hard to fit a boxer engine between the rails.  I'd probably recommend a 2.8L CRD with a EGR delete.

i didn't look into it, ,might not fit but would be nice, it's shorter and not as tall so will give tons of space for other goodies (an airtank comes to mind) and lower the CG (probably not by much but anything helps).

The thing with the Toyota is that, as Jeffy said, they are literally all over the place.  You can be in the middle of nowhere, and you could probably find parts near by.  Especially this engine, which is found in the #1 selling pickup (BY FAR!) in the region, the Toyota HiLux...

[sharpxmen]

here are as scarse as the subi diesel (or at least i think they are, didn't really look for one to be honest).

They are scarce in North America but go to any other point in the world and you'll see them all over the place.  Africa, South America, Europe...  Every time you see a truck in some remote place in the world it's usually a Toyota Hilux.
