I've got a buddy with a 6th gen coupe 4cyl with the drag kit. it makes my 6th gen seem so bland. Aside from getting the turbo kit, you proably want to get the AFC hack, tune it on the dyno and you'll have a mean machine. With a setup like that you can run 10psi safely once its tuned. if you install yourself, your looking to spend $3000-$4000 including dyno time and tuning.
