Also, new developments on the 1UZ vs 2UZ bellhousings. Allegedly, the 2UZ bellhousing clocks the trans/tcase about 7 degrees. I think it clocks it the wrong way for my application though.

cool, he will be home later tonight, ill try and get the pics tomorrow afternoon.
btw, not sure if its correct, but i heard a 2uz weighs around 675lbs.

Looking forward to the pics!!

hey cebby, sorry, hes back but i have not got the pics yet, been busy with finishing the mr2, and work. i will for sure have them tomorrow. also, true the 1uz is about 385, but remember that the 2uz is iron block, so that can jack up the weight alot. again im not sure, but ive heard 575 or so for the 3vze with iron block, so 2 more cylinders may add that much weight. i have a 3vze minus heads waiting for me at freight, ill see if they can weigh it and that might give us a ballpark.

God do I love www.car-part.com. Located a 2UZ oilpan about 40 minutes from my house today.
Turns out, I also love stupid people. Some dimwit with an LX470 never changed the oil, so the engine seized. Good for me, bad for them. The boneyard swapped a rebuilt motor into the LX470 and had the seized one for parts.
I got some grea info out of all this and learned a few things.
#1 - the oilpan(s) and pickup tubes are interchangable between 1UZ and 2UZ (probably 3UZ also). Props to Budders On Marlin's board for suggesting this. There is an (*) though (nothing major more about this later)
.jpg)
#3 - the boneyard will still likely have the 2UZ intake and TB available when I tire of the 250 horses and want to bolt on a TRD blower.
In case folks are wondering, the reason for the 2UZ sump is for clearance. Notice all the room around the solid axle in the pics abovein post 432. Since I'm heading this direction anyway, might as well plan for it. My thoughts (pre-axle swap) is that the 2UUZ pan will allow me to drop the motor down lower and to easily clear my steering/steering stabilizer. (I might be way off, but thats my theory anyway...) The other reason is that I'm much more comfortable customizing the 2UZ steel lower pan, then trying to TIG that cast alum like Muzz did on his. Hell, I could do a totally custom pan off of the 2UZ upper since I can get the flange pattern drawn up now and cut on the waterjet.

Pulled the front sump to have a look at the top half and to take it with me. Matched it up at the yard.

Front sump steel pan:

Here's the front sump aluminum "ring"
.jpg)
Here they are side by side. The sludge filled one is the one off the LX470 (glad I have access to a parts washer).
.jpg)
Here's the (*). There's some sort of sensor on the 1UZ pan that doesn't appear to be used on the 2UZ. There's a knockout, but there aren't any mounting holes drilled/tapped. No big deal, I can drill/tap it. Not sure if I need the sensor or not.

#2 - the fan oil pump and idler assembly from the 1UZ and 2UZ are interchangable. Again, probably interchangable with the 3UZ also. This was better to spend $40 than to screw around trying to make my own or playing with shorter drive belts. I had already bought the standard 1UZ drive belt, so might as well use it..jpg)

Spoastabee....
EDIT: I'm getting conflicting info on this now, so maybe, maybe not. Probably the only way I'll know for sure is to get the intake and try it myself. (the head angle where it meets the intake *might* be different)

OK, who knows what sealant I'm supposed to use to attach the aluminum ring and the oil pan to the engine? What I pulled off appeared to be a silver sealant of some sort. Anyone know for sure? I'd prefer not to repeat my water pump escapades.

Not the orange stuff which it T-case & Diff, but the Black stuff. They never leak. FWIW when I pull the original IFS pans, they have the silver stuff, but the FSM says to use the black stuff.

Looks great!
Cebby, is the wiring harness pretty easy to do on this swap? That's the part that scares me the most about a swap.
Are you flipping the upper intake around to use the stock airbox?
Thanks for doing all this test fiting with all the various parts from other vehicles. You're a 1UZ pioneer for sure!

Since my airboox is long gone, I picked up one from an LS400. I plan to make an internal snorkel branching off of it also (maybe not right away though).
I have a 1UZ ECU and full harness (actually two harnesses - the on the motor is complete except where they hacked the plug off that goes to the ECU.
The integration with the body harness is really the only difficult part. The engine harness /ecu is plug and play for the most part.
