Cooper S pulley replacement

[maxpaul]

I have a standard 2004 Cooper S and would like to fit a smaller supercharger pulley and belt
I have seen kits on e bay also with replacement spark plugs. Which size pulley would be best?
Would the engine need a remap as well? What air filter works best Would just like a little more power!
Any advise or link please
