I have a 01' viggen that my dad and I are going to use a 06 9-5 aero 260hp 258 lb/ft tq engine in. The car is going to be used for track days only. We're not sure whether to use the 9-5 turbo or viggen. And if tuning with the BSR to use the 9-3 ECU or 9-5, Your imput would help. Also anyone know where to get quality parts for good prices?
