I have a spare turbo from a 2.0T tsi motor, can I upgrade the internals for the turbo, I can't find a direct answer. Or am I better off rebuilding it stock?...
These people sell new 360 bearings instead of the 'I think' 270's we have in the k03. they also claim for $550 you can upgrade your k03 to a k04, not really sure how that works, but maybe worth looking into.
