Well, I'm not satisfied with your post, it reeks of ignorance.
Even at 3.0L the Duratec engine is borderline in size to even consider a second turbo. People tout the reduced lag (misleading, it is really a lowered boost threshold that makes the difference here) but fail to realize that even though the turbine and compressor wheels of the smaller turbo are as much as 30% smaller, there is only 50% of the exhaust energy spinning them, there isn't a whole lot of advantage in that.
The only reason I would consider using a twin turbo setup in a Duratec is for advantageous packaging of proper turbo exhaust manifolds (ie short and sweet) and since that is most decidedly impossible under the hood of a contour w/ the Duratec in its stock location/orientation, I would never consider a twin turbo on a contour.
On a contour, even if you could fit a twin turbo setup, there is NOTHING it could do that a properly sized single could not do.

.... I highly doubt the ability of a t3/t4 hybrid turbine housing can flow anywhere near the gas 2 good sized IHI or garretts can..

And if that's true, then you could just do one turbo larger than a t3/t4 hybrid,,,, not that two would even fit in a contour without a crapload of money to move a lotttta stuff.

yeah but how are you going to fit 2 good sized turbos?!

You mean like .82 housing? 500hp? How much more do you need? Better yet how much more can the car take?

Actually, it will. Go look at the compressor maps...(You do know what those are, right?)

You see.. Compressor maps are for the compressor side of the turbo . .. Thats the other side. The side the "compresses" air. Im talking about the side that power the compressor side. The turbine housing. Even with a high a/r like .82 or so your still going to run into flow restrictions. 2 exducer bores are going to flow more then 1. Less TIP is good. Its not like these cars need anymore torque then they already have anyways. IHI`s like the ones found on the probe 2.2L would go great with these engines and would flow probably better then a t3/t4 with an a/r like .82 but without the .82 `s high boost threshold. Not to mention 2 waste gates to put air away and closer turbo to head design instead of piping it all together into one turbo. If spliting up exhaust pulses isnt benificial then why do turbo`s have dual imputs into a single turbine housing? Its the same concept by using 2 turbos. The energy doesnt get as "washed" out.

ANd like a good sized turbo is mayby like the RHE5 if youv seen one you know their small mayby not as efficient as a garrett ballistics but the turbines flow well and the rest is taken care of by an intercooler.

Sorry..missed the word turbine in there ...
