Diesel turbo transplant to 20v?

[jpmahala@juno.com (John P Mahala)]

This may sound supid.  If it is, so what.  I admit my ignorance.  Today I
had talked to a guy that runs a VW/Audi salvage business and he told me
that many people have been buying up the turbochargers from older
turbodiesel Audis (or perhaps VWs) and having them mounted to their 5cyl.
10 or 20v engine.  His reason was because the older turbos would not need
to have the  "brain" operating it.  

Questions:

1) Is this true and/or doable?

2) He said that he packages all of the intake and exhaust components with
it and that it will (for lack of a better word) easily fit right to the
engine.  How?  It seems altogether obvious that manifolds from a 4cyl.
would conflict with a 5cyl.

3) Either he is feeding me a line or I really am that clueless.  Which is
it?

Please help, I'm starting to shake and sweat from upgrade fever.

Thanks,
