It's hard to say after it all repaired, but the way these engines explode I could see small dust debris get into Intercooler and piping from PCV (valve cover to Turbo). The problem is it doesn't take much to do damage when the turbo is spinning 120k.
I don't know what's covered with repairs of...
I have no idea on the warranty, I am just saying that "looks " like something that debris got ingested.
Like running w/o air filter or maybe spark plugs electrode issues.
If the blades are touching in the curved part you will see rub pattern in the housing, then the bearing is most likely...
All turbos have some radial play as the bearing is a floating one (oil cushions on inner and outer diameters of shaft and housing).
It is hard to get a good test with the turbo on the car, much easier to inspect when it's off, especially on the exhaust side. though if you took off both intake...
Glad you finally found the problem, to bad it was the turbo.
If your going to run stock turbo try and maybe keep it under 24lb, the high boost maybe causing overspeed of turbo.
It's been a long time but AFAIK, as you already surmised the main issue is that all rods and pistons are balanced.
But with regard to crank, you will probably be ok but the counterbalance weights are the journal + big end of the rod, as long as that doesn't change by a lot should be good to go...
In my link, it was just a graph showing the command value rate and the HPP value of the stock vers there HPFP. To see it click the product info tab.
I have nothing to do with them, there were also posts in this forum showing it but I didn't find them easily.
I guess there a lock-up table for low...
The HPFP is electronic too, there a command value the ECU gives and the pump tries to maintain, follow.
Check this aftermarket pump diagram as an example

Also as I mentioned if you have a secondary pump way upstream (engine compartment) and...
I am not saying this is an issue but most pumps are better at pushing then sucking, so "if" the low-pressure pump was not able to flow enough to keep up with the HP one, that might be an issue.
Seems odd though that it would take so long to show up (3yrs).
That said, I guess it didn't affect...
It's going to be hard to tell for sure until it is broken down an inspected. If you had just sweet smell, missing and white smoke, those are all symptoms of coolant leakage into cylinders, either by a blown head gasket or other damages (cracked head, less chance block).
you might also have milky...
That is good, generally you will have slight play radially, cause of the oil cushioning in the bearing (inner/outer), so from what your reporting only thing that comes to my mind is your hitting a TQ limit on that 25-26lb boost and only way the ECU can reduce TQ is by throttle limit (can reduce...
Ok, well that is good.
Are you running upgraded turbo, not that it matters much.
With that WGA lb# whats your tune target boost set to and what is your running boost.
Those chirps could be totally normal if there not much delta between WGA and actual running boost.
What I am getting at is ECU...
well, it kind of loud whine.
When turbo bearings go bad the turbo will make a louder whine, but also the pitch changes with load.
What is happening is the shaft it touching the housing side on the intake side.
I am not saying this is happening, it is just something to keep eye on in general.
I...
I am curious what noise you are hearing that gives you that impression?
This is why recordings are a bad way to test things, but I guess next best to being there, not much you can do really.
Since the recording was from under the hood, things I can pick out are.
Direct injection injectors...
It is a closed loop system, it would have to leak a lot for it to show up on boost gauge.
But you might see WGA duty cycle go up progressively to maintain target boost.
Hopefully, you or tuner will see something that may affect it.
