A standard cooper engine has a lot of different parts to the cooper s engine so fitting an aftermarket supercharger would involve loads of work & cost. If you want a supercharged cooper s you would be better off buying a 2006 or older
If your car is a 2007 cooper it's a very good chance it's a gen 2, only the gen 1 r52/53 mcs came with an sc.
the gen 1 non MCS engines are weak and would need loads of internal work and electronics as you would be doubling the hp.
Gen 1-2 totally different engine as well anything is possible but cost will be massive
The gen 2 mcs had a turbo, you could do a turbo conversion to your cooper but it would not be as good as an MCS . You would be better off selling yours and buying an MCS much cheeper and more reliable.
