2UZ: LC/Tundra/Sequoia interchange (1 Viewer)

[woytovich]

Does anyone KNOW if the 2UZ from the cruiser, the Tundra and the Sequoia are the same as far as transmission interchange? The real question is: if I had a (manual) transmission for a Land Cruiser 100 series 2UZ would it bolt right up to a Tundra or Sequoia 2UZ (separate from wiring/driveshaft/frame support issues)?

I can't see why not. It's the same engine right? Call toyota. They might be able to tell you.

i think the real question is...where are you getting a manual trans for 100-series???

either way, adapter plates can be made to fit pretty much any combo you want if they don't match up.

The only thing I can think of is the mounts, which would not be a hard to move. There is a OEM 6-speed for the 2UZ-FE that we have in the 100 Series. You may want to cross reference some part #'s and see if there is a OEM adapter plate for a 6-speed.

Here is a quick Google picture of the Tundra 4.7. I changed my motor mounts recently and they appear to be in the same location at the 100 Series 4.7L. The second picture is of the SAS that Slee did (100 Series). My question is the third picture, it shows a much different style motor mount. It's a stem with some type of dampener (Sequoia?)

So it appears the Tundra and 100 Series share the exact same motor mounts. However there is the 3rd pictures which is a 2UZ-FE but has a different mount. I can't say for transmissions though.

I'm not worried about motor mounts - this would be for a swap into a 45LV after all.

I'm worried about making a Tundra or Sequoia 2UZ work with a transmission - auto (if I have to) or manual (what I want) - that can EASILY be mated with a transfer case with land cruiser right side offset output!

The Land Cruiser 100 series drive train complete would work of course but, so far, has proven to be difficult to obtain for reasonable $.

There is one in Atlanta for $3,400 or so. It has 20,000 miles on it. The only problem is it's been sitting since 2002.

Just the drive train or the whole truck? Ideally I want a running truck so I can verify condition and have access to all the little bits that will help to complete the swap.

It's just the drivetrain. I just checked on CL and it is not on there anymore. It's been on and off over the past year. I went to go look at it a while ago and the truck was scattered in pieces all over the shop.

...and the truck was scattered in pieces all over the shop.

Not the way I want to go, not for half that price even.

What about opening up the search to v8 4runners? or a GX470?

 

[woytovich]

OK... got one for me?

 

[hoser]

Watch out for the "dial" t-case shifter on the 4Runner. I would look into the 2005-2007 GX470 since it has VVTI, 5sp AND a Torsen center diff.

What about a Lexus V8 1UZFE w manual tyranny conversion?

I have read about and given lots of thought to the 1UZ as there are swap options out there is South Africa and Australia... It is my OPINION that it would probably work ok for a 40 or smaller 70 series but the larger wagons maybe not. The difference that matters, as far as I can see, is where the engines make HP and torque. The 1UZ is a car engine built for higher revs and less low end grunt than the 2UZ, a truck engine. (is it the cam that makes the difference?)

That said a 1UZ would probably work for a street driven wagon that wasn't going to be towing or heavily loaded. An auto transmission and playing with diff gearing would probably make it work just fine.

I did not go through all the threads to see if this was accurate or not, but this is from Trunk Monkey from a few years back:

"The Tundra motor is US made and has the "i-Force" designation. The LC motor is Japanese made. There are many differences between them - cast vs. forged for example. As for the motor mounts, accessory items, etc. being the same place, I don't know that anyone's compared them."

Sadly no, just spitballing over here. Food for thought.

You may be right on that last part. I've rode with a very built 2nd gen 4runner with a 1uz and stock trans behind it (plus prerunner adapter and dual cases). With proper gearing in the axles I think that engine is a great platform for trucks, and there's plenty opportunities for improving that motor. Lextreme is a great resource for 1UZ talk.
