Toyota Diesel Engines offer plenty of options for your Land Cruiser, here is information as compiled from the Internet.
It is unfortunate that Toyota North America never offered a diesel Land Cruiser in the US Market. As a result of this, Toyota diesel conversions are very popular. Most Toyota diesels have to be sourced from overseas for conversion purposes. The most common Toyota diesel engines that are used in conversions are the 6 cylinder variants offered from 1986-current which are the 12HT, 1HZ, 1HDT, 1HD-FT, and the computer controlled 1HD-FTE.

A quick rundown of the various engines that are installed is as follows:

3B: 4 cylinder naturally aspirated; available in the Canadian market in BJ42, BJ60, and BJ70 as well as other markets. This engine takes very well to an aftermarket turbo.

13BT: turbo’d version of the 3B.

1PZ: 5 cylinder, naturally aspirated (very similar to the 1HZ; except missing one cylinder). Very limited production run from 1990-1995

2H: 6 cylinder, naturally aspirated.; available in the Canadian market HJ60 as well as other markets. Does not turbo well; low boost only.

12HT: turbo’d version of the 2H. Excellent engine and quite powerful. Very limited production run 1985-1989

1HZ: 6 cylinder, naturally aspirated. Excellent engine and is seen as Toyota’s 3rd world workhorse engine. Production run: 1990-current This engine takes very well to an aftermarket turbo.

1HDT: turbo’d version of the 1HZ. Excellent engine for a 80 series conversion. Available from 1990-1995

1HD-FT: 24 valve version of the 1HDT. Excellent engine for a 80 series conversion. Available from 1995-1997

1HD-FTE: computer controlled version Toyota’s 6 cylinder diesel. Started in 1998.

1VD-FTE: Toyota’s first common-rail V8 diesel also debuts a new twin-turbo system that delivers strong power while reducing fuel consumption as well as emissions.

    Transformed my 83, 2f 60 series, to run a 1hdfte. It is an awesome vehicle to drive now. Plenty of power, reliability, economy. New engine/gear box mounts. Replaced complete wiring with 79 series, fitted matching instrument cluster. All fitted realitively easy! My favourite toyota Diesel engine. Would love to try a 1vd later on? Maybe even the tt model

    “You my friend understand the parts needed to do the job right, that is an amazing transformation you made. Congratulations!
    (And send us some pics!!!)”

    I have a 2001 Landcruiser 100 series and want to convert it to diesel. I live in US so it is a challenge. Any ideas on what engine i should use also prices as well.
    One more question. In US only gas landcruisers so if I do the conversion how will i be able to register it since diesel is not even an option for smog checks

    “Yes, doing a modern diesel swap can be both costly and take a lot of time/patience. Some areas may present emissions or registration challenges, so it is important to do your due diligence and research before moving ahead. Sometimes it is easier and less costly to sacrifice a the year model and get an older Diesel Land Cruiser that is already complete from the factory and licensed in the USA.”

    So I have a BJ60 wagon with the original 3B motor. It needs MORE power for uphill and 4 wd. What type of aftermarket Turbo would you recommend? Or would it be better to just upgrade the motor with a modern diesel engine?
