However, at the time he shot the photos of the turbos in place, it appeared that nothing had been done inside the motor.

That clean motor was posted by someone else, and was used in a boat.

Yeah, it's common to feed one turbo from another. The point I was making is that you don't use that approach unless you are planning on big boost, and have a way to deal with the big heat which results from it. I can't imagine where he'll put a W-2-A intercooler that's big enough to cool that charge.
