General

With the new 911 Turbo, Porsche is using a turbocharger with variable turbine geometry on an gasoline fueled engine for the first time. The new 911 Turbo demonstrates once again the pioneering expertise of Porsche, particularly in engine and drive engineering. Exhaust-gas turbocharging is the characteristic feature of a 911 Turbo. The new 911 Turbo sets new standards in the competitive arena with a turbocharging technology for gasoline engines which represents a new development for Porsche.







The focus here is on new developments and modifications compared with the 911 Turbo (996). Additional detailed information can be found in the Service Information Technik booklets for the 911 Turbo (996), 911 Carrera (997) and 911 Carrera 4 (997).
