A supercharger can be purchased from all good electronics stores and many DIY stores. For example, try stores such as Amazon or Ebay, or from the official Supercharger webpage.
I would order it from the manufacturer.
You can buy a supercharger for any engine. All a supercharger is is a means of getting more air into the engine. however if you have a rather small displacement or a high mileage engine a supercharger is not a good idea. Also they tend to be in the $2500-3000 range.
You can, but if it is supercharged stock when you buy a car new (Audi A6 for example), it will do pretty poorly and since it's stock with the car, you wouldn't need to take it off, but if you buy a car with an aftermarket supercharger or you add one on and you want to take it off, you can with the same work you did putting it on.
The smallest Eaton M90 supercharger unit is typically found on the 1989-1993 Ford Thunderbird Super Coupe. This supercharger is compact in design and was specifically engineered for the 3.8-liter V6 engine used in that model. If you're looking to buy one, you can often find used units from automotive parts suppliers or online marketplaces specializing in classic car parts.
Take your hand, stick it in your back pocket, and if you have less then 10 grand to drop into a custom built S/C, buy one off ebay.
