Bummer on the engine, I was at the Upull a couple of weeks ago and I think there was at least one 22re block there. If I remember correctly, one of the 1st gens was a later one with a v6.

Made a trip to the U-Pull this afternoon. There is one stripped 1984 22R, and one stripped 1985 22RE. There was a block change someplace between 1984 and 1985. Both had flat top pistons, so I think they were the same.
Now for the conundrum. There was a 2RZ, mostly complete. It was missing the fan, front crank pulley, coils, A/C, MAP? sensor. The coils were also used on the Camry, so those would not be hard to source while there.
2RZ: Bore x Stroke = 95mm x 86mm, 142hp @ 5000, 160 lb-ft @ 4000
3RZ: Bore x Stroke = 95mm x 95mm, 150hp @ 4800, 177 lb-ft @ 4000
22RE: 92mm x 89mm, 112hp @ 4600, 142 lb-ft @ 3400.
Decisions ... decisions. Either engine is an upgrade, though I would of course prefer the 3RZ and a more complete engine.

Jon, I think you have a sickness.
But I say go big or go home. 3RZ.
I'm finding a lot of information regarding the 22R to 3RZ conversion so it seems doable.

With all you have invested in your drivetrain, you better get a hold of a bell-housing adapter before anything.
If the 2RZ is what was in my '95 Tacoma, I'd look for a good used one before I bought a builder. My engine froze when I was working on it (I thought I drained all the water, but should have pulled the t-stat housing that night). It took to much water to fill it the next day and I thought I cracked something. I got a complete motor with less than 100k miles from Capo's in ABQ for $400. Yes, $400. Of course, that was 8 years ago. Turned out I popped a freeze plug, but it was still easier to swap the motor than disassemble to get to the freeze plug.

Mission accomplished ... sort of.
A seasoned 22RE block was brought home. Very well seasoned. Pics below. Most of the work had already been done for us. The yard opened at 9:00 and there was a long line to get in. At 10:22, the engine was out and on the ground with the tranny removed.
Mike took the pics.
After, Mike and I went and looked at the 2RZ. As we were looking at it, I leaned on the front engine hook and the darn thing moved. Somebody between Wednesday and today removed the tranny at which point I was excited. Bummed that the bellhousing and flywheel were gone, but still excited since a major part of the removal was now done.
Hopes were dashed when Mike found the instrument cluster ... that read 350K miles. Then we started looking around the truck. The sheet metal was in great shape. No collision damage, which led us to believe that the truck was salvaged because of a failed engine.
So between the high mileage, the suspicious circumstances why the truck was there, the missing bits off the engine, and the fact that it was a 2RZ and not a 3RZ ... I walked away.

Have you been to the U-Pull? That place is a hike.
Congrats on the block, hope you have her back on the road soon.
Didn't see in the thread... Did you do anything special to this one? Or build it for reliability?

Without actually talking to Todd ...
The balanced crank and rods were reused, and the new pistons were balanced. Cylinders were bored .020", which leaves room for another rebuild. Deck was milled just enough to get rid of any pitting. Timing set installed in March was reused. A new timing cover was installed since the one I had was milled for the previous block, and because it was messed up from the broken chain. The cylinder head was supposed to have been reused as-is since it was rebuilt recently.
I provided most of the OEM gaskets and seals.
So, nothing special. It might not have the HP of the previous engine due to lower compression, and smaller pistons. But frankly I don't think I will notice. At least now the engine might run on Mexican gas.

Where did it go?

Either it broke off like the other, without damaging the groove. Or it was never installed.
Holy Moly, that's not good. If it broke apart, I'd think you'd have found it somewhere in the oil pan maybe?
