Has anyone done a port and polish on their R56 mini cooper or mini cooper s? I want to get one done and I want to know what a reasonable price might be before I go out and get quotes (which might be higher than reasonable).

 

Thumper Heads have done it already. Not too many people have got it done.

It is also highly recommended that a custom ECU done to compensate for your new found airflow.

 

Last time I checked Thumper Heads was charging $1300 for PnP. There are the places probably charging the same.
