Or the Subaru BRZ or the Toyota GT 86 or whatever the hell you want to call it.
There are tuning kits and then there are tuning kits, and anything from Cosworth definitely belongs in that second category. The legendary UK-based firm has now announced a stage 2 tuning kit for what we in the US generally call the Scion FR-S. The kit will add 60 horsepower and Cosworth says it's easy enough to install yourself in the garage. That figure might not sound like much, but in a car which only comes with 230 horsepower, you'll feel it.
There is apparently also another kit in the works which will take the horsepower up to 380. We're looking forward to that.
