Hard-core CEG'er
Maybe not the same platform, but those turbo's are tucked up against that engine fairly tightly... I'm pretty sure someone could make them fit in a Contour. It doesn't appear to be sticking out further then the AC compressor.
The point was never "is it physically possible" for twin turbos on a contour. The issue was always, that it would take a tremendous amount of time, effort and money, for zero net benefit compared to a properly sized single turbo setup such as is available commercially already from NPG. Several folks have started down the road to do it, just so they could be different (which is honestly the only good reason I could come up with for bothering with it) but each one of them has eventually given up because it just isn't worth it.
The Mazda6 posted, it appears to be a bit easier to put together, but even if it isn't, all it means is someone spent the time money and effort to get there. (and with a way too small intercooler to boot). Great for them, but in this case, it won't perform any better than a properly done single.
