Toyota Land Cruiser: The Difference Between FJ40, FJ45 And FJ47

Question: I like the classic Toyota Land Cruiser. What is the difference between FJ40, FJ45 and FJ47?

Answer:

Johnny is partly right. This could be more than what I was looking for, but here is a brief summary:

"J" is simply the code of the Toyota Land Cruiser platform. Each Land Cruiser has a "J" in the model name. It may be due to copies of World War II Jeeps, but to my knowledge it has never been an official explanation.

The first part of the model designation indicates the engine. "F" stands for a 6-cylinder inline engine. Over time, there have been many variations in the engines of the "F" series, commonly referred to as "Prime F", "F", "2F" and "3FE" (the E indicates fuel injection). There were also 3F engines in countries outside the US. In 1993, the 6-cylinder in-line engine was fundamentally changed and designated as 1FZ-FE, for which the designation of the model was "FZ". This was followed in 1998 by the engine 2UZ-FE with the designation "UZ".

"H" and "B" are designations for diesel engines. Similarly, over time, there have been several engines, the most popular, the 2H and the 3B. A 1978 BJ40 would look identical to a 1978 FJ40 except it would have a 3B engine instead of a 2F.

All "J4" Series Land Cruisers have essentially identical backgrounds (in terms of body style) but different configurations for the stern. Johnny gave up a decent summary. 40, 41, 42, 43, 44, 45, 46, 47.
