Not to sound condescending, but there are a lot of things that could combine to go wrong on any turbo engine that could easily amount to $3k. One spun bearing could put you in the $2-3k range if you're not tearing it down by yourself, which I am presuming the OP ain't.
4 good tires for this car are $1000-$1500 for Pete's sake.

Come on. Of course major things can go wrong, question is how likely is it on these engines?
The main reason turbos are being replaced on the n54s is due to leaky waste gates. And turbos that fail in those circumstances are covered by extended warranty issued by BMW.
Op is looking at n55. Have not read much here, if anything about people having to replace failed turbo on n55.
Same with spun bearings. Do not recall reading even a single case where this has happened. Not to say it hasn't, but it is not something one needs to be overly worried about on these engines.
The fact is, these are very stout platforms, aside from a few known issues such as shitty water pumps and the failing hpfp (which has been resolved).
Chances of having to drop 2k on a single repair is very unlikely.
There is nothing special about the tire requirements on this car vs. any other sporty car. not sure why you are even bringing it up.
