Looks like I have tracked down a 4BD1T with 135K miles, its a 5spd truck but I do not think that will be an issue?

You will not pass Oregon emission testing with a mechanical diesel installed in an FJZ80. You will need an emissions exemption or a change of registration fuel type to diesel. This is between you and DMV. Be aware there is not a step by step process for this. If you aren't willing to jump through some paperwork hoops you should do what 95% of diesel conversion folks do and register your vehicle in an emissions exempt area.
There is no lift needed. If you do a conversion where the oil pan and front differential interfere it is a lot more practical to properly modify the oil pan than lift the vehicle. There are lots of skilled welders and fabricators in the portland area who can do this for you if it's not something you want to tackle.
The all wheel drive is retained. It is unaffected by the diesel installation.

The transmission type does not matter with the Isuzus. The only thing I need to be aware of with the Isuzus is if you have an engine from a non-NPR application you must tell me how the rear crankshaft seal is retained (in it's own housing or in the transmission adapter) and I need to know if the engine is a 6BG1T as these use different size crankshaft bolts.
If you have an engine from an NPR you have nothing to check.
Yeah it's a 1990 NPR, would get the whole truck.
69rambler,
Now you really have me thinking here about this NPR option.... The only conversion I've herd about was the guy in NJ from Mud. ** EDIT** I take that back, that was a Mitzu Diesel... You must have some demands for these going into 80's in order for you to go into production. Do you know of any rigs in OR that have this completed swap? I'd really like to check one out, as the idea of keeping my drive train toyota is very appealing for my application.

Are the GMC panel trucks the same in terms of drivetrain as the Isuzu NPR? I know they use the 4bd engines.

The GMC W series cabover trucks are rebadged Isuzu's.
I have the same quetion, im actually looking at getting a NPR based on this adapter so i would like to see some information on this engine swapped into a 80 series. Im very seriouse about doing this swap.
I'm not sure that taking out a really great engine (the Toyota 3.4) and putting in a reefer/gen set engine (Cummins 3.3) or tractor engine (Kubota V2203) is a swap that "makes sense". At least for me. Obviously an LS could be a tire fryer and destroy *most* Mercedes diesel engines out there, but an LS is no diesel. Nor will it get 30+ M.P.G
The FJ60 swap guys are reporting 22-24 with various transmissions. This swap is super tempting when my engine dumps the head gasket. I just want to see one in an 80 and get some feedback.
Brooklyn ny!
Do you know this guys handle , maybe he can do my swap?

The V2203-DI is a reefer engine, the 3.3 is a universal industrial engine built by Komatsu for Cummins light market with a Cummins/Bosch fuel system. They're used in a wide range of applications including mine spec Tacomas- Retrofits, but they work, well. The agreement between Cummins and Komatsu was inspired by Cummins looking to supply efficient diesel engines for the mini truck market in the US. This is spelled out in Cummins press releases after the agreement.
There is nothing wrong with the 3.4 V6. They have an excellent reputation and serve the market well.
However, like almost every Toyota engine made the 3.4 has a very broad power band without much low end go. If you prefer engines with grunt you'll like the 3.3 a lot better.

As far as I can tell its not been done in a 80 series yet. Supertech on here swapped a 4D34 mitsu into his 80 sucsessfully and has had good results.
I have no issues making the Isuzu 4BD1T/2T work in my 80 series. Slowly collecting parts for it now, going to reserch what one I want (1T/2T) while I get the rest of the parts for my swap.
Having a company making the adpater from the 4BD to the Toyota trans is a huge help and step in the correct direction to make this swap a reality.

Supertac does swaps in south jersey... Find him on here and his links on YouTube. From what I've read he has the 80 up for sale :-(. I wish my buddy back in jersey dust just drop coin on a 2012 Taco.. He's a diesel mechanic himself ad that would have been a sick rig to score! Has me thinking if its still around come the holidays I might have to pay him a visit when I'm back home
Wheeling- Why Isuzu over the Mitzu...? You seem to have been on this path for a bit now, help me to understand you choice.

Isuzu VS Fuso
Isuzu parts availability is better.
Fuso? WTF is Fuso? is what you will get when looking for parts.
Both are doable, Isuzu has better support.
Very true on the Mitsubishi vs fuso comment. Only the larger fuso engines >7 liters can u find parts super easy
I'm worried though as to if the 440 in my 80 would stand up to the aggressive tq of the Izusu and cummins engine not to mention the excessive vibration.
I look forward to any swap updates.

any obvious issues with running the 4BG1T in an 80? I know it's a little bigger, but is it too big?
