The idea of twin turbos has been floated around a few times before, i thought of doing it once, but after getting some old T3s and trying to figure out how to plumb everything, I figured i would be better off with a single turbo.
So far it would seem that no one has tried it. But the turbo you just removed is capable of holding in the mid 20s, Dave S. spends some time there, although his engine is no completely stock.

There's a guy over at oilburners who just posted pics of his setup....I can't remember the exact details though...maybe a PowerStroke turbo feeding the stock turbo (some other turbo feeding the stock turbo anyway). Turbo 1 lives under the truck, turbo 2 right where the stocker lives. I can't remember if he's got an intercooler or not.

Staging turbos can be tricky but the motor won't take it anyway and you won't be able to burn enough fuel to get the hot air volumn to drive them.

Do it! I'd love to put twins on mine when I get the money. You're going to need more then head studs to keep compression in the cylinders though. ATS offers heads with built in fire rings but they're about $2,500 I think. Dropping the compression a bit wouldn't hurt either and you'll definately want an intercooler and sum bigger injectors and a built pump. It won't be cheap but it sure will be cool!

IIRC the guy that set this up is not running any insane boost numbers i think 18 was his max. the motor was set up with studs and such to handle boost but it was more for quick response.
the smaller turbo could boost quickly from the get go and the larger one can boost at higher rpms. not so much more boost but quicker boost over a greater rpm range. he seems real happy with it.

Turbo boost pressure is the result of supplying more air volume than the engine can use.
So if you increase the air volume, you increase the pressure.
The higher the pressure, the more volume the engine gets.
