Can it be done?

I have a 2002 Buick Century Custom with the 3.1 liter six. I am curious as to whether or not a supercharger featured on the more expensive models can be installed on my engine in a fairly painless manner.

you mean like the l67 the 3.8 liter supercharged engine...i don't think it can be done. and if it could it would be very costly
