GT's are not supercharged, GTP's come with the S/C motor, so if it's a stock GT theres nothing in this for you, i'm sorry to burst the happy bubble if you were looking at a stock GT, but if its a gtp, you can swap the motor in with the intake clearance issue, and there's a kit with the necessary wiring here: http://www.zzperformance.com/grand_prix/products1.php?id=173&catid=108
