That was a BADASS rig!!
No, but I'm daily driving a double cab right now and towing a trailer w a few thousand lbs and it certainly shoots along just fine
Beyond the manual trans option, why bother? I am missing the deal with all these engine swaps. The diesel I get, the V8 maybe if you are going to a substantial boost in HP, but an engine that makes 15hp more and less torque seems like a terrible idea. Plus the GR engine requires more RPM to create less torque. I don't know about you, but my Landcruiser is a big heavy beast, not a light weight sports car that needs a high revving engine (relatively). You can modify the 1FZE and more HP and torque in a range usable for the heavy beast.
If you built a 1FZE engine 1mm over, with a minor bump in compression, a slight upgrade in camshaft and a few other tricks inside, I think you can get over 300ftlbs of torque and 275+hp without a hit to durability or using a bunch of aftermarket parts that are hard to come by in the field. Should you choose add a turbo and a few psi and you are well into the 400ft range.
Now if we just had a better ECU option.

Out of curiosity, why don't people look at the 2uz w/ h151 matchup? Toyota built 100s with this combination and foreign parts for 100s would be much easier to source.
Sometimes there isn't a deal. Sometimes it's just because they want to.
Think about it for a moment. When people first started swapping 350 SBCs into 40s, there was probably a significant amount of people who had this same mindset, "the F/2F was sufficient, why bother with the big nasty V8? You don't need that extra power"
My point is that he wants to do a 1GRFE because he wants to (as far as I know,there isn't any indication otherwise). Maybe it will turn out really nice, who knows? One user went as far as to swap a 5-cylinder GM Atlas engine in his 80, and he loved it.
Noobie, don't let these guys discourage you because you don't want to use the biggest baddest engine in your truck.
If your goal is just to have fun and have a challenge/something to do and drop money into, go for it.
Many times I have thought about the same swap and even considered a 3UR for a bit.
ANYthing can be done if you have the will and $$ to see it through.
Why swap an axle with something else if you can have one custom made?
If something is in the way, move it somewhere else.
I'd get started by taking an 80 with a dead engine and stripping it completely apart.
Get the frame on stands and gut the rest.
Then its just a matter of effort and $$.
Go for it and keep us posted!

Thank you for the information. I wasn't aware that the 1gr was introduced in other parts of the world. This would make it easier by far. My problem is not electrical but the figuring out what transmission would fit and if needing any custom parts outside of my capabilities, it could be a deal breaker.
So what is the question?
A 1GR-FE is in many non-US Land Cruiser 7x iterations with an R151F/split case combo behind it.
It is also available in GRJ200 versions as well mated to an auto box and a chain driven xfer case.
The engine would work well in an 80 series platform.
The problem is going to be with the engine ECU and mating it to the ancient 80 series electronics.
90% of a swap like this would be caught up with dealing with electronics in solid state and communication issues. The 1GR-FE relies A LOT on the electronics to make it run.
Nonetheless, good luck if you go this route. It would indeed be ground breaking.

I'm not sure if the 1gr ecm came with an immobliser in all years or in later years like the 2gr. A lot of the spyder runs dual ecm., I run a standalone. Only issue on the spyder running dual ecm is that the temp guage doesn't work (about 8 wires from one ecm to the other). On the older mr2, sw20, no problem besides a check engine light for not having an auto ecm. Sw20 and fj80 should have about the same electrical components from toyota. A 2gr with headers and exhuast, the 2gr ecm respond pretty well. Dyno seems to be 275whp.
I'm not looking for big numbers. I just want something oem, reliability, newer, and although no resale value, some bragging rights will come with the swap. A manual transmission is a must!
There is an upside to a left drop conversion with a ra61f from the fj cruiser. Not cost effective imo. You get a 6speed and newer transmission but hard to source (my dad wanted to to swap a 6speed for him).
I'm going to be looking at a 95 and under because in Wisconsin, there is no smog for 95 and under. I could register the truck it in another county and be done with it too if using a 96 or 97. An older one would cut cost down by far.
I've driven a fj cruiser and I like it besides the blind spot and a bit too wide for my taste. Otherwise my dad tows heavily from Arkansas to Wisconsin.

I am almost positive that not all model came with immobilizer. Hint, the way many folks want to try and mate the e153 with a 1gr in a mr2 finding out that even though the 1gr and 2gr is the same family, they have different housing.
I am thinking, 5-7K for a landcruiser, $2500-$3000 for engine, $1000 for transmission, $2000 for bits and pieces (clutch, metal stock, cutting tools) to mount it in is more than enough. Remember mounts and wiring are going to be done at home.
I didn't spend much on my 2gr. The engine, tranmission, clutch, metal needed, the rest was just what I wanted versus what is needed to get it on the road (racing radiator, ems, fuel flex sensor, fuel pump, fpr, all AN fittings, coolant AN fittings, fuel and coolant lines, headers etc). Cost from a shop was $16K turn key, nothing special like I did (AN fitting, ems, fuel lines, cool lines, radiator, maybe a cheap clutch or at your cost). I spent 10K on the swap but by subtracting all these other things that I didn't need but wanted, I think it is doable.

I understand your desire to do the swap you mentioned, although I agree with a few posters above in that the overall amount of work involved for what I would term "limited improvement" is not something that would contemplate.
There are quite a few other reasons I would not consider this type of swap personally and the leader among them is parts availability. If you do an LSX/NV4500 swap you will have far more gains in the HP and Torque department but the big factor in the LSX swap to me is the availability of parts in the aftermarket both stock and performance. This set up will also allow you too keep the right drop T-case and maintain your rear DS offset as it came from the factory.
I applaud your desire to try something

^Thank you. I am always open up for option too. I am almost certain that I will keep a toyota engine. Parts availability can be a determining factor especially aftermarket, but I'm just looking for a cruiser in style. I have no goals in aftermarket performance. I rather use that resource to modify another project for power. IMO a 1gr will do everything I need it to do and some. Everyone will have a different approach and goal in mind. I want to do other builds. I'm getting old but for sure, I will retired of these pleasure. Just not sure when. Next 10 years max? I just want to wake up, drink coffee and do some yoga 30min every morning.
I also forgot to add in new drive shaft although not a deal breaker. Cost locally is not expensive.

Each to their own when it comes to conversions, but i certainly wouldn't contemplate a conversion with the 1grfe when there are so many better alternatives..1HDT,3UZ, 1VD-FTV keeping it toyota or LSX , Cummins etc.
I think I would rather a plain 1FZ over the 1GR..my brother had a toyota kluger company car with one and they are a revvy engine with horrible economy & that's not even considering I weighs 1000kg less.
You sound like you have skills noobie , and I'm not against doing something different as far as conversions go I just think there are much better choices..but in the end if it makes someone happy going down that path then go for it.
I think to get a 6 speed behind it I would rather something like a tremec with a tranzilla transfer case adapter as well.( depending on what engine it was going to go behind though,as the ratios aren't your typical 4x4 types)
