Why not search around on fleabay etc to buy
JCW parts second hand. There are lots of folks selling
JCW superchargers, pulleys, airboxes, injectors and Gp intercoolers... keeps that
JCW looks, costs less, etc ... then take the parts to a reputable company like ThinkMINI, 1320, GTT etc etc and ask them to fit it all for you. I'll bet that the price will be far less than 3500 fitted. The
JCW map is often found to be a bit lacking in quality and many of the folks who run big numbers actually use or revert to the stock BMW S map or a custom tune like GTT or RMW
