The cooper s pre 2007 are supercharged and can get a works upgrade to around 220bhp !!

The new cooper s has now been turbocharged so should see some nice power hikes in time!!!

Personally i would have a civic type-r as there 197bhp N/A and bang a rotrex supercharger conversion on and the sky is the limit 400bhp+the baby conversion kicks out 330bhp without intercooler!!
Where the jackson blower conversion is 290bhp and about maxing out due to heat!!!!!!

These cars are phenominal with a supercharger !!!The cars are taking up to 350 bhp with no internal mods as the engine is bulletproof and quite a few lads have done 20k+ milege hard and no problems!!!
