Hey guys first time poster here but wanted to share what I thought was important information!
Recently my 2016 Landcruiser blew the bank 1 head gasket between cylinders 1/3/5
Finding a used Landcruiser motor is near impossible and easily double the price as a tundra or sequoia 3URFE.
I took the plunge and bought a tundra 3URFE for my Landcruiser and I wanted to share what was different and how I made it work for half the price.

1st difference: Valve covers (mounting points for harness and noise filters are different, it is not necessary to swap valve covers unless you’re anal about things being perfect)
2nd difference: Oil cooler mounting bracket to block ground is different but can be swapped over (it’s just two 12mm bolts)
3rd difference: PROBABLY THE MOST IMPORTANT DIFFERENCE. It’s important to note that the Tundra motor does not have an oil level float in the upper pan like the Landcruiser does. You can either swap upper oil pans or you can cut the connector on the Land Cruiser harness and wire the two wires together to make the system not through a light. You will still have your oil pressure reading but no (Low oil level) message if you run it low on oil.
4th difference: Belt tensioner and Idler pulley are different and need to be swapped.
5th difference: Air intakes will need to be swapped due to the tundra having a vacuum port for vacuum brake boosters vacuum supply. The Landcruiser has an electric booster and doesn’t need this. (worst comes to worse you could cap the vacuum line from the tundra intake)

I believe that’s everything! Hope this helps someone out there

Is the Tundra engine now up and running? All the harnesses were plug and play with no codes?
 
Love this. Finally someone has cleared the air with specifics of what's needed to transplant a Tundra/Sequoia motor into a cruiser. Only 18 years after the 200-series introduction. Surprised it's taken this long.

Maybe time to turbo the LX. Since there's practically and endless supply of good use motors for the taking.

Thank you @16landloserbro !
 
Great post, A+! There has been a lot of speculation about this on the forum, but little concrete data. Thanks for working through it :D

Also curious on this…

Is it up and running???
 
Really glad to see concrete info being posted on this.

@16landloserbro or @GrouchyTech I assume this was the non-flex-fuel version of the tundra 3UR? Any insight into what those differences might be? If those work as well that’s even more engines in the supply.

Off the top of my head the FFV ECM software and fuel pump are definitely different from the Regular Unleaded/E10 engines. The injectors MIGHT be.

Yes everything was plug and play from the landcruiser harness. You will have an unused connector to the oil float. But that’s the connector I wired together to bypass. Otherwise it was plug and play.

You bet!

I was struggling to find any info before hand. So I just took the plunge!😂

I don’t think the flex fuel tundra would be compatible. It maybe with the old ecm and such but tubing and fuel pumps are different
 
cool write up, OP! paging @gray rider
 
@gasman4u: This is a nice alert, thanks! I will update my thread also, soon.
