[s-cars] anyone here successfully rebuild a turbo?

[David Kase]

I have considered the same for my 2.7tt.  It came down to the HUGE pia it
would be if a turbo failed after I rebuilt it.  It would be worth the $1000
for the two K03's on the B5 S4.

For an UrS the situation is different.  It might be worth the risk with the
much easier R & R procedure.  Let us know how it goes!  ;-)
