k, first off...to set the record straight...Scion's do NOT use turbo's nor supercharger's on their cars....as of yet. Seeing as how these are the 1st generations. Also...I seriously doubt Toyota would make an engine, mate a turbo to it and only get 150 hp out of it, so re-think that. Next...the amount of aftermarket equipment out for the tC's are very limited, but the ones that are out are VERY expensive...and not everybody has that kind of money to spend...hence the DIY section of HAN, . Just tell skoopa if it's do-able or not.
