The 4.2 v. 2.7t post made me think about turbo life. When was the last time...
...anyone here had a turbo go?
Every time someone mentions 2.7 reliability, there are a responses about turbo fragility. However, it is extremely rare that anyone posts about the loss of a turbo. This leads me to the conclusion that the 2.7 in the C5 body is generally pretty reliable and that a turbo that sees regular oil changes can expect to live a long life. This is especially true of stock, unchipped cars running synthetic oil.
What say you, C5 forum? Anyone lost a turbo lately?

Turbos are very robust when taken care of... meaning, good, clean oil feedings.
I design and build turbo kits for older BMWs and have owned a couple of old Saab Turbos (tweaked of course). I put 250K miles on the original turbo on my Saab SPG and there are currently 45K miles on my '86 BMW 635 twin turbo. I use Mobil 1 oil with 10K mile change intervals (filters every 5K ) and have never had a turbo failure.

No karma worries here. I agree. I think 2.7t turbo reliability...
especially on non-chipped, non-2000, cars with over 50k miles is way, way "overblown".
Certainly I can remember a few lower mileage ones going and a few chipped ones going. But I can't remember the last time someone who fit the above description posting on a blown turbo.

Previous owners are definitely the biggest 'X' factor in terms of whether
they kept clean oil and adhered to cool-down procedures after spirited driving. Or even knew that turbos require such things in the first place.
Having said that, it is generally agreed that the stock K03 turbos have rather small oil galleries and small turbine shafts that can exacerbate problems resulting from neglect.

That'll do. I assume you were careful not to run lean on stock fueling? I'm not sure where
on the boost versus RPM curve the stock fuel system becomes insufficient (or if that's even possible on K03s regardless of peak boost).
