Anyone see this article in Sport Compact Car? Sharp Precission Instruments combined the OEM Roots supercharger (stock) and a Garnett GT28R turbocharger. Aside from the suspension and brakes the rest of the car remained stock - pretty much - except for cosmetic changes. They claimed 265 whp on a Dynojet dyno. (I think a stock "S" runs around 175 hp.) No mention of the price this kit runs for though.
