(1992 – 1993) Porsche 911 Turbo S 3.3 (964) – Ultimate Guide
Porsche made a lightweight version of the Turbo simply known as the Turbo S. This used the spartan appointments of the Carrera RS with an upgraded version of the Turbo engine. Some cars received graphics on the side celebrating IMSA Supercar Championship. Roland Kussamaulat Porsche was responsible for the Turbo S and he used many lessons learnt with the IMSA Supercar Championship cars to improve the Turbo. This included uprated suspension and larger wheels which allowed for bigger brakes.
Moreover the driving lights were relocated into the headlights for the Turbo S which allowed that space to be used for brake ducts. Similar to the Carrera RS, the Turbo S had no power steering, air conditioning, airbags, central locking, alarm system, rear window wiper, smaller window washer reservoir, smaller horn, and had thin-gauge glass.
The engine used a second oil cooler and slightly higher boost to improve overall performance. Further modifications included revised camshafts, injection valves, single fan motor and a red air filter housing. This was hooked up to a 5-Speed manual through a lightweight flywheel and special thrust plate.
Just over 80 of the Turbo S models were produced in Grand Prix White, Maritime Blue, Black or Midnight Blue Metallic with custom-optioned interior colors.
