So, question for y'all.
Both turbos blew at WOT, but never had issues before then. One blew around 3000 RPMs, then other at 4500.
What "foreign" object could possibly trash these turbos? The only thing I can think of is carbon buildup inside the head, or a piston ring, or maybe a bearing.
But in the latter two cases the engine continued to purr just fine afterwards, and after the first one was replaced, no additional oil usage.
In other words, it's gotta be WOT related.
The only other clue is that I had hesitation off idle. Really had to feather the clutch to get the car moving, and I knew there was something wrong - thus the reason for taking the logs in the first place.
I think it's oil starvation of some sort. Oil at idle wasn't getting to the turbos, making them sticky. That's my best guess at this point, but who the hell knows.
