So far I see that Street Flight makes a Turbo Kit (http://www.streetflight.com/turbokits.htm) for the Contour V6 that sells for $5K. And Thomas Knight that makes a superchager kit (http://www.boosthead.com/product.php) for the V6 2.5L engine that sells for $2K. Are there any other options? Knight offers a warranty where as Street Flight I can't tell. I would also rather spend 2K than 5K. Has anyone installed either of these? I would like to hear opinions.

Thanks,

Dan
