High IATs, tight ring gap, and rapid onset of boost are the likely causes that triggered its doom.
After sulking for a while I dusted off the 4.8 that'd been sitting in the corner forever and finished it off:
In the meantime we tore down the 5.3L, and found that 3 pistons had left the chat:
Plunked the 4.8L in:
Completely rebuilt the hotside... and added an intercooler and a better discount brand turbo:
And brought it back to life on April Fools day:
Brakes, body work and paint, and some interior and exterior bits and it should be good to go. Gotta eat the elephant one bite at a time.
