what is the meaning of fj?

[mrtoyota]

What does fj stand for?

[FirstToy]

Good question-( I would like to put this common question in the FAQ )

FJ comes from the engine designation of the orig FJ40.

In Land Cruisers,
The first letter is engine code (F, for example). The J means "made in Japan". The number is the model (40 series, 80 series, 100 series, etc)

So, for example:
FZJ80 = 1FZ engine, J (made in Japan), 80 (80 series body)

On the FJ Cruiser, the "FJ" is meant more as a historical tie-in. The FJC's official designation is GSJ 15. The engine in the FJC is a 1GR-FE (note that the 'FE' seems to be used on all engines- 1FZ-FE, etc)

The FJ Cruiser shares much of it's mechanicals with the Land Cruiser Prado, which I am guessing justifies the Cruiser name in FJ Cruiser.

Please add factual data or corrections, thanks!

B = in line 4 cylinder diesel
F = in line 6 cylinder gasoline
H = in line 6 cylinder diesel
U = v-8 gasoline


J = assembled by Araco(Arakawa)
Z = 4 valves per cylinder

Thus, FZJ80 is an 80 series Land Cruiser with an inline 6 gasoline motor with 4 valves per cylinder.


FJC = ????? A made up marketing designation, unfortunately. They should have called it something else in my humble opinion. Even "Prado" would have been cool and more accurate. There is nothing "F" or "J" or "Cruiser" about them. I still like them though.

I believe the FE designation is only on the newer engines to denote they are Fuel Injected.

1FZ-FE

In ancient Land Cruiser history, the very first prototype was the AK10, produced in January of 1951. It used a B type 3386cc 6 cylinder gasoline engine which was installed on the SB type 1-ton truck chassis. Toyota called its prototype the Toyota Jeep, and by combining a B-type engine with a Jeep model it was known as the BJ. Large scale production of the Toyota Jeep did not begin until August of 1953.

In June of 1954, responding to claims of trademark violations by the Willy's Corporation, Toyota renamed it the Land Cruiser.

The FJ25 made it's debut in August of 1955. Technically, this would be the first Land Cruiser with the "FJ" designation, and there were a number of differences in this model from the BJ.

The first B type 3.0 liter 4 cylinder diesel was introduced in 1974 in the BJ40. Interestingly, the H type 6 cylinder 3576cc diesel was introduced in 1967, apparently installed in a 40 series.

The above information is from "The Land Cruiser - Special Issue of the 50th Anniversary", published by 4x4Magazine Co., LTD of Tokyo in 2001. This book was available through SOR, but is now out of print. Their description is item number 403-100.

It's a fantastic book, loaded with history, trivia, specs, stories by some of the original designers in their own words, lots of great drawings and photos. It covers practically every model from the AK10 through the 100 series, including models I had never heard of before, such as the FJ35 wagon.

Happy cruisin'!

I would think that mr toyota, of all people, would know.

[crushers]

"J" is JEEP
<sheesh, i thought everyone knew that>
;^)

okay i have a question to build on the first question, Why the number designators? 25, 4x, 55, 6x, 7x, 80, 100?

And in this tech sheet by www.cruiserheads.org too

http://www.cruiserheads.org/series/codigo/codigo.htm

(article written in Spanish, but easy to understand, since it is mainly composed of codes)







Here's a great example description. (translated below)





Translation:

Familia de motores= Engine Family
Codigo Nase= Base Code
Volante del lado izquierdo= left hand drive
Distancia ente ejes corta=short wheelbase
Techo Duro=Hard Top
Manual de 5 velocidades= 5 speed manual
Equipamiento LX=LX trim
Configuración Regional Europea=European Regioanl Configuration

LOL! It's been a long time since I've been to Willem-Jan's site. I had forgotten how long his main page is.

[cruiser88]

I think just the E designation stands for fuel injection as in the 22R-E. The F I think is for overhead cam or something like that. This was all discussed in 80's tech before.

You are correct. The E designates fuel injection. The F is the "head design" according to this source.

The next digit (the first after the dash) designates the head design. "G" is the DOHC performance head, generally with a more aggressive valve angle for higher rpm/more power. "F" is the low-end torque and fuel-efficient DOHC head, with less aggressive valve angles. If there is neither an “F” or “G” in that digit, then the engine is a SOHC model (probably chain-driven). Toyota did make a few OHV engines, but they are much older and by now quite rare.

Nice, I was closer than I thought. Just missing a few details.

FJ = Foreign Jeep

Not disputable. Oldest fact in the book.
