Intake / Exhaust System (6 M/T)
1. Exhaust system
11 Turbocharger
A largenozzle 10.5T turbo has been adopted in order to improve mid to highrange torque. Optimum control of the
supercharging pressure has ensured good torque and response at medium engine speeds.The positions of the turbine housing and the wastegate holes have also been changed to achieve smoother outflow and
increase lowspeed torque. Along with these modifications, the wastegate valve has been changed from an oval to a circular
valve.
