For those of you complaining that the xA and xB are unique but painfully slow cars, a supercharger kit designed by Blitz can now be fitted to the econoboxes to improve performance. Three electronic settings will allow the compressor output to adapt to the driver's motoring style. There aren't any hard numbers to speak of besides the $3500 price tag, but faster is always better, right? Then you'll just need to upgrade the suspension to put handle the extra power, the wheels and tires to deal with traction issues, and brakes to keep the whole operation under control. Maybe you should have just bought a stripped Cooper S. The best thing about the kit is its ability to play nice with dealerships— since the parts are sold and installed through the Scion network, no warranties will be voided.
