supercharging a rotary would normally require custom intake manifolds.
Theres some info on supercharging in the forum. just search for them.

The best setup is a turbo. The 'currently available' bolt-on kits are a joke at best, and you're better off spending the money on a rebuild, porting, exhaust, and some tuning. You'll likely make more power with that than the bolt-on chargers. If you can locate a no longer produced Paxton kit, they at least work to some degree, but don't expect much.

Trying to stick some random roots blower you found in the junkyard on there? Save yourself the trouble and don't bother. Unless you're going twin-screw, there's no point, as it's just a waste of time, money, and you'll get more torque/HP with a properly sized turbo for a quarter the cost.

More information needed:

Is your car an S4 or S5?

Are you planning on using the stock EFI, piggyback ECU, standalone EMS, or carburetor/dizzy?

Are you going to use a Camden kit, old Paxton kit with a new pulley, junk yard supercharger, or some other supercharger?

If you are using something other than a Roots type supercharger, what will be the max boost level?

Are you planning on retaining the OMP?
