ok ... calm down ...
the op wants one, you lot have given many reasons as to why it is not really worth doing,
if you really want one then its your choice, however I do tend to feel the chance of finding one will be rather hard.
think it was some audi turbo, tbh would be easier to get someone to make you something for your car rather than trying to source a second hand kit from yester year ...
or email van aaken and ask if they can make you one, if you google hard enough its amazing what you can find...
