All generations of the Porsche 911 Carrera belonged to the most sophisticated sportscars of their time.
In 1998 the legendary Carrera 993 changed to the type Carrera 996.
In the meantime this model is established and Porsche made the developement until 2008 to the type 997.
TTP/Lotec developed already in 1998 a twinturbosysten for the carrera 996 3,4, which is still the same concept for all Carrera 996 and 997-1 until model 2008.
The entire conversion requires no external modifications to the car.
The win of the english Tuner Grand Prix 2006 was a milestone for the TTP carrera 997 turbo.
