Turbonetics has a kit for the 07-08 tC w/ claimed increase of 100whp for $4300. the TRD supercharger is about $3k with increase of 40hp. However, the supercharger is designed to work with the stock motor and is a good compliment. The turbo can get expensive, because along with the $1300 premium over the s/c, you will need to upgrade brakes, tires, suspension, transmission to safely handle all that extra power, that will put the tab to just under $10k. Unless you have a wad of cash to put into this car, I would just take the superchager. The tC is kinda pricey to make really quick, thats why I stopped investing money into mine, I'd rather start with a quicker, more capable platform
