Here's a video of tearing down a blown 1UR engine (the 360hp direct injection version of ours). It's interesting to see how the engine is constructed:

That would be a great swap in an 80 series. It could really use the oomph that the six never really had!
Although I would have stayed with a Toyota V8 for the swap. Then you're still able to go to a dealership for parts and service instead of mish-mashing between Chevy (GM) and Toyota.

Having seen a few hundred various engines torn down in my time this was pretty well put together. I wish we had that dual fueling PFI/DI system, I could really make some power out of these if we did! Just waiting on some free time to get the SW unlock for the controllers. Anyone try swapping a 1UR-FSE in a 460?
An 80 series would be great outside of the 4-cylinder power and V8 fuel economy
. I've seen a few threads online where people have done a 2UZ swap into an 80 series. The UZ compares really well with the first-gen 5.3/LM7 LS in terms of power but can't quite match the fuel economy and swap-ability. I LOVE my 2UZ through and the idea of keeping things all Yota!
My first thought as well, how hard would it be to convert our GX 4.6 into the LS 4.6 version? What are the differences? Or would it be an entire swap?

The heads would be different due to the DI. There may be small differences that make them incompatible with our blocks or manifolds.
The guy in the video said that the engines are easy to find used and are cheap, I guess because they rarely fail so there's a lot of good ones coming out of wrecked cars. So it'd probably be easier to drop in a used replacement motor along with ECU.
I wonder how the low end power is on these. That's mostly what I find lacking on the GX compared to the Tundra. Once it's revving it makes ok power.

Funny thing about when people start talking about how easy it'd be for swapping an LS into a ________ (fill in the blank), my son-in-law also. He wants to stuff an LS V8 into his 2021 Taco.
Well, in general it's not all that hard for a conversion, all you need is a big arse hammer, custom exhaust manifold and a bunch of plate adapters for the trans, etc.
The ONE thing that NOBODY EVER CONSIDERS is the computer and electronics.
Unless it's a kit, trying to get your new engine to play nice with ALL the rest of your vehicle AND be smog legal (at least in CA) is no small feat.
Physical installation is a relative breeze. It's all mechanical. Wait until you have to wire everything up.
That's why if I were to do an engine swap (assuming something bigger/more cylinders), I'd stick with a Toyota motor. It may be an easier swap.
1UR-FSE used in LS 460 also has the port/direct injection setup.
The 1UR-FE in our 460s was used in LS460 in other markets in the world. IIRC...tuning was around 325-330HP in those applications.
The electrical work would probably be hardest than anything since I'd imagine you'd almost need to drop in a new wiring harness or go mad dog custom here and there. Not all 460s are wired the same.

Yeah my thought was take the ECM, harness and engine and swap it. Just depends on the CAN comms between both vehicles. Haven’t modded Toyotas that far prior. Just a thought cause I’m pro DI but having both solves 90% of the DI issues.1UR-FSE used in LS 460 also has the port/direct injection setup.

Agree with all the issues associated with engine swaps noted above, including my own.
I did a 215 ci aluminum block V8 engine swap in my old 1974 Chevy Vega wagon when I got out of high school and that was a headache even without the computer and all the smog requited today. Albeit, I didn't have the collection of tools I have now, which would have made the swap much easier and faster.
Boy, was that fun after I got it running!!! Ear to ear grins all the time!
In short, engine swaps are best left to pre-smog, pre-computer vehicles.

Don't know why, I'm ALWAYS missing at least to of them...
