Wasn't that setup referred to as a "Banks stage V" deal? I seem to recall some pics in one of my turbocharing books. You might be able to use that term to help you in your search.
As an asside, I think Tony Scarlota had a 20' V drive cruiser with that setup on it a while back. I know the boat was sold, but maybe he knows where it went and if the guy used the turbo deal.
