Topic: FJ40 curb weight

[RN37DD]

 Any idea's on the curb weight of a 1970 FJ40? I been told that they are on the heavy side and that's why they need a 6 cylinder or V8. But so far the specs I've found have them at 3265 for soft top and 3470 for the hard top. My 1979 SWB Toyota pick up weights just under 3000 lbs. About 2900lbs at last weigh in. I'm thinking my truck would weight around the same as a fj40 soft top, if it had a F Or 2F engine in it.  Anyone know how much a Toyota 2F 6 cylinder engine weighs?

Did a bunch of checking around. And got 2F engine weight results from 650lbs to almost 800lbs. 700lbs and 750lbs being the most common weights. Dose that sound right?

Sorry, I don't know the answer, but I am very curious. My guess is its nearly 4,000 pounds

More searching and reading. New numbers but they're pretty close. Soft top FJ40 3263lbs and 3427lbs for the hard top FJ40. Funny, I also got 3792 lbs for the FJ40 with the 2F engine. I think the 2F and F engine weigh the same. Maybe the FJ40 just got 300 lbs heavier in 1975  .

Wow, interesting numbers. We have a '77 at the shop right now, it would be cool to run it down the street and get it weighed but it's a customer's truck so that's not gonna happen

look what  i found in the glove compartment.   This 1969-1970 owners manual has the FJ40 soft top curb weight at 3260 and the FJ40 hard top curb weight at 3470.

This post might make a good stickie!

Cool, Thanks! Now i know how much my 1970 and 1971 hardtop FJ-40's weigh...

I started thinking about the fj40 and engine weight in case I installed a newer style engine. Like with a 2.7 I'm sure it wouldn't weigh more than a t100 or gen 3 4runner. A lighter engine like a 3rz or 22re might bring the soft top FJ40's curb weight to below 3000. But first I want to get this F engine up to speed and see how it dose. Looks to complete to pull out just yet.

I'd shove an aluminum v8 in there waaaaay before going with a 4 cylinder

Ouch! Wonder what Big Mike would say about that Nate!

Nate is suggesting running dual-3RZ-FEs in there which I think is a sweet idea

I vote for a 4bt...........That would be killer.......

The bj came with an excellent 4 clyinder diesel, one which I'd search high and low for looooong before putting a 4bt in.  I'd actually rather stick a 1kzte in before that too, something like 125 hp and 295 ft lb torque stock, plus it redlines at a much more reasonable rpm.

[BigMike]

According to my records...

Engine	Type	Valv/Cyl	Year	Disp.	BHP	Torque	Bore	Stroke	CR
1KZ-TE	SOHC	2	95	2982 cc	125@3600	219@2000	96 mm	103 mm	21.2:1

But it's Turbo, so up the booooooost

[kneedownnate]

I've found conflicting claims on the torque, but they've all been near 300.  Is that 219 nm or ft lb?

[BigMike]

I've found conflicting claims on the torque, but they've all been near 300.

Hmmmmm I have trusted my source in the past, but their Toyota diesel applications are a bit sketchy so I wouldn't be surprised if my number is wrong

Is that 219 nm or ft lb?

Good question, but a pound-foot is greater than a newton-meter, so 219 lb-ft torque would convert to somewhere around 160 newton-meters probably

Here is my source for Toyota engine data (the site is VERY old and I've been referencing it for years)

That may make more sense then, I just saw another last night saying 315 nm so    Either way, everybody I've heard talk about running one has been thrilled by the power output

My #1 choice would be a Toyota diesel also.    This swap looks interesting. Lots of old running 300D Mercedes at a low price around here. And the engine weights 200 lbs less than the Toyota F engine. The people that make the kit are called 4x4 labs. I don't know anything about them, but it looks worth checking into.  

[RN37DD [OP]]

I fixed the starter and threw in a set of spark plugs. The old 1F Toyota six still runs.    So I think I owe it a chance. Stock it put out 145hp@ 4000 RPM and 217 ft-lb torque at 2000 RPM.

Just as a comparison, I started checking the curb weight of the FJ60. Lightest spec was 4246. An Fj60 Owner said his weighed 4800 at the scale with him in it. others said 5000 lbs or more.  So I'm guessing the Fj60 weights 800 to 1200 lbs. more than an Fj40.

Picked up a new engine manual. Print date February 1971, No. 98042. Covers the improved F engine starting with engine number F243298, with a supplement section for engines starting #F294920, October 1969.  This is for the FJ land cruiser and FA gasoline truck. Engine weight with clutch and air filter 633.6 Lbs. With the 2 barrel carburetor and 7.8 to 1 compression ratio it was rated at 155 HP @ 4000 RPM  230 Ft-Lb @ 2200 RPM.  8)

I weighed my FJ40 at work and it tipped the scale at 3750lbs with bikini top and trail gear onboard.  With hardtop and camping gear it was over 4000 lbs.


Almost forgot to mention that was with a smallblock, SM465, and 35" SXs...

I've got a 77 fj40 with the aluminium body and it weights 5500 pounds or 2.4 metric tons
