the cost will vary since you going to need to get some stuff along with the SC. you going to get the SC, upgrade the clutch, exhuast, jr boost upgrade, vafc, guages, etc etc. it would be at least 3500+ more than likely 4000-5000maybe even more, depends where you buy your stuff and the brands you get too.
SC will cost around 2500-3000 + upgrade boost controller, fuel controller, clutch, flywheel, , headers, exhuast etc etc. that if your car is completely bone stock.
If you don't mind going turbo importparts has a good drag turbo package which comes with alot of the stuff your going to need for around 3000-3500 , plus some other stuff.
