Differences and Similarities between Prado (120) & FJ Cr

[FlyNdrive Advanced Member Find all posts View Profile Close FlyNdrive]

Guys,

I was in a parking lot yesterday and ran across the Lexus GX 470. I parked next to it and snapped a few pics with the camera phone for you guys.





It got me thinking of the differences and similarities to the vehicles.
I will post pics of specifics later, but lets list some similarities to the vehicles.

Here on the forum I have found....

The same 4.0 L Petrol engine,

same Pre-Cleaner,

Upper control A-Arms,

Bull Bars,

Accessory light switches,

Dual battery tray,

OME Shocks and springs,

There is a lot we can share here, so if you have anything to add....speak up.

Thanks

The Fj comes with 2 types of tires. The basic model comes with P265/75R17 Bridgestone Dueler , and the TRD comes with 32" BFG A/T's on a 16" rim. I don't have the original tires, so I don't have the load and speed ratings. The rims are 17 X 8".

As for loading the FJ weighs in at 4,295 lbs. and has a gross vehicle weight of 5,570, so it has 1,275, but I have loaded mine a lot more than that.

The tow limit is 5,000 lbs. and a tongue weight of 400 lbs.

I hope that answered your questions.

Keep 'em comming.

You don't have any room to talk "down there". What the hell is a kilowatt??


Real men use HORSEPOWER.

[Chippy Addicted PP Member Find all posts View Profile Close Chippy]

But we stopped using HORSES years ago when one of your countrymen invented the motor car :lol: :lol: :lol:

Maybe I'm just not old enough to understand these golden oldies :lol: :lol: :lol:

I'm emphasizing more on the POWER part. Watt seems a little weak.

Yeah, we still use horses. I got your horses right here......

i'd reckon with corporitisation and toyota being one of the larger car manufacturers across the world, there probably using one chasis or slightly changed for a number of vehicles, hence the reason the FJ and 120 have similar/same parts???

[FlyNdrive Advanced Member Find all posts View Profile Close FlyNdrive]

That's what I'm working toward. I would like people to add the similarities, so we can help with mods and technical issues (even insult each others weights and measurement standards along the way).

If anyone has any questions about parts they may want to retrofit or upgrade for the Prado please let me know. Us Americans are crazy about moding our vehicles and have resources that may be unavailable for you.

Yep thanks Ben,

Your car should have a placard (metal sign) attached usually on the body work visible when the drivers door is open.

On this it should list the rims & tyres legal on your car. Amonst the figures will be the speed rating & load index of the tyres permited as a minimum. Anyway this is the way they do it downunder!

I'm curious that a version of the FJ can actually fit 16inch rims, since as far as I know we can't do that on the 120s due to the brake caliper assembly being too big for it to fit.

Cheers & thanks for your input on the forum!

Re: Differences and Similarities between Prado (120) & FJ Cr

Here is some information on the sesignationns for "FJ" "BJ", and "GSJ15" There is also some information on the Prado 120.

For the FAQ- Info on the history of names and codes, member's name in bold and their post following

Here is some info on the GSJ15 designation.

1GR-FE is the code for

1 = First Generation of the block (2003)
GR = This is the engine family or GR-series aka Gas Research
F = Economy narrow-angle DOHC
E = Electronic Fuel injection

Toyota GR engine - Wikipedia, the free encyclopedia

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.

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

F
2F
3FE
1FZ-FE

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.

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.


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.

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

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

History of the Land Cruiser Family Tree

Toyota Land Cruiser History

The 120 (Prado) is the 90 series replacement (70series--->90--->120)

while the LC's follow this line (50series-->60--->80--->100)

The FJC is based on the 120 platform They share common parts from the LC Prado & 4Runner.

70 series
The first requirement for the new series was that the new Land Cruiser should not sacrifice any of its toughness, so a strong ladder frame was outfitted with rigid leaf springs. The body plates were thickened by 1mm for added strength. While leaving something of the image of the 40-series, such as externally added fenders, it was also given modern features such as curved glass.\
However, the 1st generation Prado had inherited too strong a workhorse image and did not attract the interest Toyota had hoped.

With a full model change in May of 1996, the Prado embarked on a new and independent path. This 2nd generation design was aimed at creating a car that retained its 4WD character while looking at home on city streets. It reflected Mr. Yoshii's experience while doing development work on another Toyota vehicle, the Carib. Then a Land Cruiser was used as a support car during snow testing. The heavy Land Cruiser often got stuck, while the Carib was "light enough to run circles around it," as Mr. Yohii puts it. Although he had no idea that one day he would be put in cha rge of Land Cruiser development, that experience helped him create the lighter, more car-like characteristics that made the 70-series such a success.


90 series
In May of 1996, the 70-series underwent a makeover and emerged as the 90-series Prado, an independent series. The design was heavy-duty, like the 70-series Prado, but with a smaller engine and light classification

Aiming for supremacy in all classes, Toyota developed the 90-series Prado as its final weapon against its main competitor, the Mitsubishi Pajero.

120 series
Toyota's new Land Cruiser is aimed at the core of the Sports Utility Vehicle (SUV) market and replaces the current Land Cruiser 90 in Toyota’s comprehensive SUV range. Like all previous Land Cruiser models, the new Toyota Land Cruiser offers full off-road capability - but, in response to the growing leisure market, the latest model adds superb on-road driving pleasure with new standards of premium car quality and comfort.

120 series tree

2003- Land Cruiser Prado 5 door & 3 door introduced in Europe. This model offered w/ several engine options including the 4.0L V6 (all new design)
2003- 4Runner & GX470 introduced in America. Using the same frame, suspension & tech; the 4R is offered w/ the 4.0L V6 & 4.7L iForce V8 (V8 came w/ new 5spd fuzzy logic transmission)
-------GX470 uses much of the LC Prado body except different fascia, tailgate and trim. Interior is upgraded quite a bit over the Prado and exclusively uses the 4.7L V8.
-------Both the Prado and GX have air rear suspension instead of coils. This was an option on the 4Runner.

------ Tacoma uses a similar front suspension, same 4.0L engine. Basically from the A-pillar forward, it is nearly identical to the 4Runner/FJC/Prado mechanically. Rear uses leaf springs and frame is not fully boxed.
------ FJC is a modified Prado/4Runner frame (shorter wheelbase, but not as short as the 3 dr Prado). Identical suspension to the 4Runner. Auto Trans, front diff (8") and rear coil susp the same as the V8 4Runner. Same 4.0L V6 as the Prado/Tacoma/4Runner.

----- All models are a creative mix of the 120 platform parts bin. Take a bit from the Prado, take a bit from the 4Runner, etc.
----- The body of the FJ Cruiser is all-new and based on the showcar that debuted to overwhelming popularity, thus the decision to bring it into production.
----- The production FJ C is the first Toyota to actually say 'TOYOTA' on the front grille since 1994 (?) Even the concept car had the Toyota "sombrero" oval logo. I believe in more an effort to tie in w/ the original FJ40.
