2nd turbo?

Hi, I'm the owner of a black 1996 850R wagon, and I'm thinking about putting in a second turbo, running in series with the stock one. A friend of mine pulled something similar with a Porsche, brought the compression up to some insane figures, and his car HAULS. I was leaning towards a second high-pressure Volvo one, any advice?

P.S. - The gray plastic on the trim strips has all cracked off, and it looks horrible. Is anyone else having this problem??

Would that even be possible? Dont you need a car with 2 sets of headers? Like on a V engine?
I can see where you're coming from, with the flat 6, but do the flat 6's have 2 sets of headers? How would it be possible to add a 2nd turbo to an 850 if it has an odd number of cylinders and only one set of headers?
Well for there to be 2 turbos, you need 2 sources of exhaust, for any turbo for the turbo to spool up, it needs exhaust fumes. So I do not see how this will work if there is only one set of headers. 2 headers would be the way to do this.
