Aw, come on - you and I both know this thread should be titled "Making Lemonade: Life Lessons"
Or, "How Not to Buy a Turbo'ed 1FZ-FE"
you guys realize that over sizing the pistons will increase the compression ratio as well as displacement.

Rick, yes, we are using a thicker Cometic HG which should help with bringing compression numbers down.
just checking
Yep, even if slightly.
Here is a calculator to figure out the difference.

Ali and I had also talked about "improving" the compression over stock. But things like decking the block to off-set any decking that was done to the head start messing with the timing and the tensioners ability to work properly, among other things. So as it sits, absolutely minimal work will occur to the head if possible and ditto for the surface of the block and then use the thicker HG with ARP studs and hope that compression numbers are reasonable. The shop may have advice as well since they build up turbo'd V8 Fords, etc.
No.
For the 1FZ-FE you have standard size pistons (what the rig came with OEM), .5 over and 1.0 over, with corresponding rings.
That's about it from Toyota.
Onur, you and Ali always impress me with your being there to help out when ever needed
Actually on this job Ken, Ali's taken the lead since he has spent some time with Robbie rebuilding a 1FZ. He's done a grunt load of the work. Of course, it helps he has time while I have a full time job.
I provide parts support, my house for the wrenching/rebuild, sleeping quarters, food and beer support, and my labor when I have time.

Mike--Are you committed to the turbo build?
Seems like it would be a good idea to get a stock motor running well, get the mess home and worry about the turbo aspect later.
You're lucky to have the Ali/Onur team working it for you.

Andy, we do have a contingency plan that if anything regarding the turbo tests as questionable a block off plate will be used at the exhaust manifold flange where the turbo typically sits. That's the most straightforward approach given the exhaust and other changes under the hood. It'd be a challenge to actually make it all stock.
And IMO, putting a turbo like this (~6 psi) or a supercharger should make no difference to a motor that has been gone through to the extent that this one will be. Once in NM I'll go through the turbo system and make sure it tests properly, remove the UniChip and turbo-timer boost control, and set it up in the most conservative manner with the original Safari specs of manual waste-gate actuated at 6 psi.
I'm still waiting to hear on the injectors - that will be interesting if they all test out fine.
The coolant system should be as good as it can get when we start it back up.
LandTank has loaned me his LM-1 AFR gauge and ScanGauge w/ laptop interface so we should be re-starting this with the right things being looked at.
Yes, very lucky to have the friends that help

See Mike, listen to the man.
you're kidding right? this from a guy that's put less than 2K miles on his 80 since Death Valley 2004
Note his sig line: driveway queen!!!

4k. Get it right, OK?
Mike,
How is the wear on the oil pump idler bushing and are you able to reuse it?

are you referring to the 'bushing unobtanium' or something else?
Yep, that's the one.

to my naked eye, it "appears" to be fine. However, the engine shop is aware of its preciousness and will clean the block accordingly.
On the flip side, it's not a Toyota carried part but it is a metric size and is obtainable if necessary. If needed, one can yank it out, clean the block with corrosive stuff and then install a new one.

UPDATE:
Picked Mike up at the airport last night.
He's been transferred to Beowulf's abode for engine rebuild.
Let it begin.
