Probably the 7MGE that Toyota used from '86.5-91 in the Supra & Cressida. I did that swap for under $1000 with a few trips to the U-Pull-It beforehand to collect parts and a JDM engine.
Here's my write-up for anyone interested

I am doing an OM617 in a 2nd gen pickup. The Benz is a good combination of cruising power and torque. Parts are available everywhere, including the US and it is a common engine. I would love to do a 1PZ(-T) or a newer common rail Toyota 4 cyl with all the great electronic control, but it gets expensive fast. I have done a 1HZ and turbo in the FJ62, so my expectations are realistic.. an HZ into a 2nd gen pickup is just too much. Lots of complete 300 sedans going for 1500-2500, and the adaptation to a Toyota drivetrain has been worked out. It is probably one of the cheapest and still enjoyable ways to live with a diesel as the Benz motors tend to rattle less like a tractor compared to others motors in that economy swap class of diesels.
Ultimately it depends on what you want. I couldn't find a 3RZ at the price point the Mercedes can be had for (with a bonus body to sell off). No matter what you do, you still have to do about 1000 in small bits and whatever it will run to adapt to a drivetrain.
Would love to do a twin turbo 1VD-FTE one day.
I really just like the simplicity of diesels over gas. The HZ has 4 wires operating it. Like that Toyota workhorse (longest run production diesel motor Toyota has ever made), the Benz is used all over the world in harsh conditions, like bush taxi in Africa. That gets points in my book, because I tend to use the trucks in harder environments and far from any population.
I love the idea of a OM617 but I haven't found a lot of people who have done it and I figured it may be a little bit too heavy...please tell us all about.

Just a reference:
7MGE - 463lbs
OM617 - 563lbs
Cummins 3.3 - 560lbs
The swap is simply a plate to match up bolt patterns and machining the fly wheel to work and also adapt to make the Toyota transmission input shaft fit onto a pilot bearing. 4x4Labs has a complete kit, with new billet flywheel, that makes it easy. I am using a setup that was already done that the guy removed to go to a V8. He machined the adapter plate himself and had a local shop machine the flywheel and do the pilot setup. He was turning 39s and a 617 isn't enough for that task, though he managed to break an IFS rear axle on 37s with the 617.

Was just looking at craigslist vancouver and found something interesting. A mitsubishi 4d56 turbo diesel engine for sale. I looked at the specs of this engine and found it to be very similar to the 22re already in my 4runner. 2hp extra and and extra 40 ftlbs torque and around the same weight. A bonus this engine has is its cheapness...a similar toyota diesel is much more expensive and very hard to come by...These engines have the benefit of having the a stock intercooler as well where most toyota engines do not come with one as standard. I think I found an engine swap winner...Anybody have any other thoughts
I love the thought of diesel swaps, and have entertained doing them for years. However, IMO, the 22RTE will be a far easier swap and much cheaper to maintain. Power is easily and reliably run up into the 170 hp range, and torque over 200 ft/lbs. Mileage remains excellent for a small gasser. I installed a built LCE 22RE in my 85, and wish I had done another 22RTE.
I've been researching the 2.7 3RZ swap to replace my 3.0. It equals the same HP (170) with almost as much tq (177 vs 190?)
4 cylinders, better MPG, easier/more room to work on, I'd be happy. I don't have a 5 speed so it'll cost me a bit more. Just another option for you though!

22rte...Yeah that would be so cool...I found that engine for sale actually...Im not to worried about diesel maintenance, I have diesel specialist friends in High places. I can use there stuff to rebuild injectors, pumps and turbos. So Cheap Cheap Cheap for me to own a diesel....But yeah...22rte...I would love one of those.

Yah I think that is what he has. It is shoehorned in there and barely fits but is a really nice motor for the truck.

Swaps of engines not sold or serviced in the USA have NO business on a vehicle you have to rely on in the back country of North America, any more than a North American market gasser has any business in the Sahara. If you're truly venturing into parts unknown and less travelled, you want RELIABILITY. Stick with something you can get parts for ANYWHERE. Even a cheap part from a mom and pop auto parts place in BFE can get you home.

That said, and largely agreed with, these are MY opinions:
A swap only makes sense if several of these are met:
1. The replacement is very cheap and a direct bolt-in, like trading out a 305 for a 350.
2. The original engine needs a major overhaul/replacement
3. The replacement engine offers improved performance or economy- fuel efficiency is important for range, too.
4. The engine can be installed using mostly savage parts and very few adapters
5. Engine/parts are widely available
6. Is a direct bolt-in.
There is no condition 1 for early Toyotas. The following make good candidates in my mind for various reasons, although I'd only consider them under condition 2:
OM617- meets 5, potentially 3, as it has much better low-end torque. You best be handy cutting, welding and fabbing though.
2L-T and 3L- both would need to be imported, but the 2L-T was available in America at one time. It is a direct bolt-in. A fuel harmony could make a case for these, like a camp truck that shares the heating oil.
3RZ- I think these are really the ticket for early Toyotas, even if they're not a diesel.
The 1KZ is just to expensive and I think the VW 1.9 TDI is too small. A hot-rodded anything does not a good travel companion make.

I met a guy a good while back that ran a 2LT in a 1st gen 4runner on veggie. It a perfect fit for the truck IMO. He's since sold the truck and his site is long since dead but you can still pull it up on wayback machine.

Thanks for that link! I was wondering why I couldn't find any info on this truck!!! I remember seeing it years ago

Havent read all the posts in this topic, but I did a 1KZ-t swap in my 1994 Pickup/Hilux. Almost everything was bolt-on, just not the engine mounts and exhaust. Its a great engine I've taken 200 hp out of. Driving on 1,3 bar with an IC and 3" exhaust. Later it'll another 50 hp with porting and balancing.
The weight is almost the same, and it runs with a tranny from tacoma(?).

What transmission/bell-housing are you using with this? The sligt drawback for the KZ an North America is that it was never sold here, so parts aren't available as readily. They are nice motors though.
