In my opinion: if I was you, I would (and I will be too) go with a supercharger. Not a centrifugal supercharger or a "vortech" supercharger. Get a belt driven twin scroll supercharger. I think we can all agree that the thing that the FRS lacks most is torque. A supercharger is better in the low end versus a turbo. The added weight and location of the supercharger wouldnt affect the balance of the vehicle as much as a turbo would either. And since the FRS/BRZ's claim to fame is balance and cornering, why would you screw that up. That being said, if you're looking to go with 400+ hp and smoke mustang fanboys on the highway, you might think turbo. It has more potential for more power. Although, then you will have to change your whole cooling system (IE. radiator, hoses, thermostat, etc). But it all comes down to what your finish line goal is for your car. Then again, if you want to spend 6g's on a turbo, you might as well buy a 2JZ and swap it out. Motor will run you about 6500.
