Hi, Paul.....I found the following turbo for sale, and would like
your opinion. It is a 1988 S4
turbo.  Is this one of the "good year" turbos?  He is asking $125.00
for it.  Thanks for your
response. Paul Conner

That is not the good year as far as I can tell from just that picture.
Is it cracked
between the two turbine exhaust entrance ducts.
