Is a 2f worth it? (1 Viewer)

[DAD2SIX]

I have a 1f in my 40 thats having some trouble. If I go 2f am I going to notice that big of a difference? A google search tells me the stock f is 125 hp and a 2f is 135 hp Is 10 hp worth it? If I do go 2f all the used 60's I have found have 150 -190,000 miles on them. And am I buying another high milage motor you can't find rebuild parts for? Either now or in the near future like the F. Or should I swap in a 350? That I'm familiar with. (I have built up many for other projects)

Yes I did read the FAQ. But that info and advice is going on 10 years old! Part availability has chanced a lot. What does today's market think?

I am no expert on the F engines, but my understanding is the 2F is better in terms of reliability (better oiling system) but not necessarily a vast performance improvement. I think the 2F/4speed combo just feels more put together primarily due to the synchronized 4-speed transmission being a significant improvement over the 3.

As for the 350 - you will earn the ire of all the purists and F-enthusiasts on the forum - but, as you realize - parts are ubiquitous. If this 40 will be primarily road-driven, a 350 is a great engine. The higher torque band causes it to suffer a little off-road in low-speed/high torque situations. I have an old 283 in my 40, and really like how it drives (and sounds).

There are about a million other swaps but that is my take on the couple that you mentioned.

I would stick with a LC straight six either way , the vehicle is designed for it's torque band and a V8 just won't do that . I do believe there is a pretty good gain in torque between the early and late inline sixes...

If I wasn't already set up for a V8 - I'd want a 2F, a 3FE (if you don't mind wiring up the computer) or a diesel. From my understanding though, the 3FE/diesel swaps are less straightforward, more than a little complicated!

I was in a similar situation when I bought my 69. It had the original engine with an unrepairable cracked block. The closest thing to original that I could source at the time was a 74 F1.5 . If I had no more issues than you have currently found I would fix what I have. Have you driven one with a 2F or SBC?

Swapping just for the sole gain of 10 HP is not worth it. Swapping in a later 2f with 150.000 ish miles on it, if you can find a good deal, is a good idea. Lots of FJ 60s are starting to get parted out, so just find one and desmog it. You could also do the 4 speed as mentioned. It is a nice convenience to have a synchronized, and slightly lower, first gear. You might even swap in the 60 series power steering if you want that also. There are a lot of FJ 40s around that run very nice on both the trail and the hiway without having a v8 swap. A 3fe setup would be nice, but a lot of extra work fitting all that electrical stuff into it. I have helped build a 2fe in a 78, and it is super nice, but a lot of extra time, talent, and $$$ to do.

I agree with inkpot. The drivetrain from an fj60 has a lot of merit. I've got a '78 with the original 2f and a '76 with a later 2f and the later engine is "better". The later split transfer case is stronger and quieter, but you have to solve the parking brake problem.

If you're going to rebuild a motor, get a later 2F as you can still get parts for them. If you do a rebuild of a 2F, I wouldn't worry about the motor going bad before the rest of the truck rusts away (unless you run it out of oil, that is). Most everythign will swap over from the F to the 2F. Will C (onesprung60 here)put a later model 2F into an older FJ40, but put the F valve cover, air cleaner, and most of the other 'F' parts on it. There is a build thread here. If you're looking at a 2F, get one from an FJ60, along with the transmission, t-case, rear axle (for parking brake) and steering box.

The 3FE is an interesting option, though the wiring is somewhat difficult.

A 5.3 vortec, IMHO, would be one of the better options (and I used to be a Toyota purist). The fact of the matter is, there are numberous, off the shelf parts you can get for the swap. You can go to any parts store in north america and get parts.

You can still get parts for earlier 2F's I just had a 77 2F rebuilt, pistons, rings, crank shaft, cam, the works. Good luck w/ it, I really like mine.

I'm going to recommend that if you go that route, you don't bolt the F parts on the 2F. If later on you decide to add power steering, you will have a very difficult time getting everything to line up with the pulley on the power steering pump using the earlier F water pump and balancer. My truck has a later 2F and had all the earlier F components bolted onto it. I had to source the correct parts when I installed my power steering set up. It still has the F manifolds, and as soon as my exhaust manifold cracks I'm going to switch to the correct later 2F manifolds.

Well I decided to keep it Toyota. I bought this today. I got it for the motor. The 4 speed and the power steering! It's a 1984 FJ60 with 154k he was asking 1200 on the net. I got it for 800! It runs and drives sounds smooth and runs a lot better than my f ever did. But it is stuck in 4 wheel drive. It will go into 4 hi, neutral or 4 low but not 2 hi ?? Not sure why yet. Man That 4 speed sure shifts a lot smoother and faster than my 3 on the tree! I checked compression they are all about 120-125ish Assuming I fix the tc is it a good one to have? Is it best to remove all the emissions crap and run the stock carb?
Or is my f carb ok?
My plan is to take what I need off the 60 and part the rest out.

 

[nelsonjm624]

Good call, and nice score, de-smog it run either carb, I ran my old f carb w/ no problems. As well as all the accessories in the exact locations as the F.

 

[bikersmurf]

I'd run the slightly wider 60 axles also.

You won't regret swapping to discs.

 

[uglyoinker]

I've eye balling that one for a bit. I should have gotten it. My silly bum has brought home 3 cruisers and 2 Chevy donors in the last month so I had to stop myself. After you're done taking what you need let me know and I'll take the rest. I keep a collection of cruisers for parts. Please keep me in mind.

Any idea if i can use the fuel pump off my f motor on the 2f? I just bought it from Kurt a month or two ago!

 

[nelsonjm624]

I would assume so especially if your going to use the F carb, but I reckon it don't matter I'm using a "2F" fuel pump and old F carb, everything swapped over from the F easy pezzy.
