Thanks for your replies!
There was other people talking about it, but I guess they weren't talking about the Cooper S because they didn't mention anything about the air intake, etc.
I'm sure glad I asked instead of assuming it could be done!!!!
Glad to hear you love your Dooper

I have a chipped Audi A4 TDI and am looking to get into something smaller. It will be a lot less power in the Dooper but it should be a lot smaller and lighter and hopefully loads for fun to drive
Thanks again,
Matt
