I'm very skeptical about the whole idea of supercharging/turbocharging an engine that was not really disigned for it. Sure the engine will be built appropriately for the conversion (you would hope so) but then you have to worry about the breaking system, transmission, clutch, chassis the list goes on...oh yeah and insurance and registration and the police..oh man seriously save the 12 thousand and put it towards a rexie or *salivates* an astra sri.
