Motorsport 968 Turbo RS thumb|right|275px|Porsche 968 Turbo RS. Between 1992 and 1994, Porsche Motorsports Research and Development built and provided a full "Race" version (stripped out 968 Turbo S) for Porsche's customer race teams. The 968 Turbo RS was available in two variations; a version using the K27 turbocharger from the Turbo S, which was built to the German ADAC GT specification (ballast added to bring the car up to the 1,350 kg minimum weight limit), and an international spec version which used a KKK L41 turbocharger with the engine rated at and a reduced weight of 1,212 kg (2672 lbs). The interior of the Turbo RS features a single racing bucket seat with six point harness along with a welded in roll cage required for it to be eligible. Other modifications included a modified 6-speed manual transmission having altered gear ratios and a racing clutch along with racing suspension. Only 4 were ever produced as privateer racing teams found the contemporary 911 Carrera RS 3.8 race car to be of more interest. Barth and Büsing, p. 184. These are the rarest 968s ever produced.
