That's a good point. I don't know how to fully diagnosis it. I am going to school for mechanics and after this class, I plan on engines and rebuild classes.What's really WRONG with the old F engine?
Ya, I keep going back to either rebuild or LS swap. I'll check out that fuel injection system!This is one of those slippery slope topics that can go lot's of directions.
If and when I get to build my dream rig, it will be powered by a connect and cruise LS power-plant (or very similar)
If you don't want to go down a spendy path, but want decent reliable performance and keep things stockish, I would HIGHLY recommend going with the Holley Sniper 2300 Fuel Injection System. It will get you up and running, provides some good power from the stock motor, and wont take forever.
Thank you, this is all great info. Wheres a good place to purchase engines? I see new and used all over the place but have no idea who to trust.The Toyota 5.7L is VERY VERY wide... 30" @ the heads. For reference, an LSx is ~24.5". Add in minimal aftermarket support, and it isn't something I'd consider doing without having deep pockets and resources. The thing it does have going for it is the light weight(a hair under 500lbs) No easy, USA factory available manual transmission is also a HUGE turn off for me(ie parts and tuning).
Back in the late 90s, I pulled out a low mileage rebuilt 2f in my 75 FJ40 and dropped in a 5.0L TBI. PLENTLY of engine to move the cruiser around with 35s and 4.11 gears. I wouldn't go out of my way to get the same engine unless it was free and even then I'd have second thoughts given that LSx engines are cheap enough to get.
10 years ago, I dropped a 6.0L LSx in my FJ55. VERY nice swap to do. LOADS of aftermarket swap support.(ie cheap) Easy to find one with low mileage. My 6.0L was 34k miles when I bought it.
~7 years ago, I dropped a turbo 5.3L LSx in my second FJ55. Still waiting for results as I'm working with a shop on/off for 'SEMA quality' results.
~3 months ago, I started down the 472 big block cady swap in a third FJ55. HUGE off idle power that is ~650lbs. It is an odd esoteric choice but it should fit the bill for towing and snow plowing application For reference, an iron block LSx engine is 580lbs
I think a cool swap for an FJ40 would be a Cadillac LF4; factory twin turbo 3.6L engine rated at 402hp/430ft-lbs in a nice ~350lb package that came with a manual tranny.
I do keep seeing a lot of Diesel but I am not so sure I want to run Diesel. I'll have to keep doing my research. There are so many back and forths with diesel. Its hard to make out the right pros and cons.Slippery slope indeed.
I would try a compression test first. That will tell you all you need to know. If compression is good, just clean it up and tune it up, and send the carb to Marks Offroad or JimC and have it rebuilt.
Next step could be Holly Sniper Fuel Injection.
As for swaps, I'd go the LS route. Cheap (in terms of engine swaps) it's been done a ton so no real gotchas and plenty of parts available.
The Toyota would require quite a lot of work and figuring things out on your own.
I had an FJ40 with a 350 and I put TBI fuel injection on it. It ran pretty dang good. It's all about what you want in your rig. I like the toyota engines, and I'm ok with LS swaps. Diesel is where it's at
Thank you for this knowledge. I am hoping the pistons are fine or just need some cleaning up and new rings and what not. Wont find out until I finish the first couple projects.X10 on a compression test.
It sounds like a good idea to rebuild an F till you’re knee deep and discover F pistons have been NLA for many years.
I love my SBC. When my 1.5F died in ‘96, it was either part the truck or convert. I could but a very nice 40 for the $3500 to rebuild Uuthe F in ‘96. $2500 put a SBC in the rig with: new clutch, 120 A alternator, and exhaust.
To do it again today I’d pick up a good running 2F and be ahead $2K or swap in a diesel. A diesel swap wouldn’t be worth it now... it’d be 10 years before the fuel savings would cover the cost of the swap. For now I’m enjoying a 350 that’ll pull steady from 400 rpm, and still get decent MPGs.

I prefer driving diesels. That said unless I had a diesel or cheap access to one, I’m not sure I would do it. It will never “pay for itself” on mpg or longevity, maintenance.
Diesel swap only makes sense if you really just want diesel. Which is a pretty good reason
