Tork Tech Inc. makes a manifold kit that will allow you to bolt just about any roots or twin screw on a 2 valve, but it will take some work. It has a blank top plate so you can fit the 03-04 Cobra blower on, but it takes a bit of engineering, measuring etc. and $$$. The 03-04 cobra blower (Eaton) is a Generation 3 and 4. You would be better off buying the kit with the Magnuson/Eaton Generation 5, since it is already up 50 HP over the old ones with the new case design. Here are some pics and a dyno sheet.
