I have a 99 Forester S-Turbo. Do anyone know if I can replace the my original turbocharger with a Impreza GT/WRX turbocharger? Will this turbocharger fit without any modifications? or do I have to replace fuel injectors and ECU from a Impreza also? Have anyone tried to replace the original ECU with a Impreza GT/WRX ECU?
