USEFUL INFORMATION FOR FACTORY TOYOTA DIESEL LAND CRUISER ENGINE CONVERSIONS
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:
