In the 1992 Le Mans FISA allowed the old turbo Group C cars (i.e. Porsches) to be entered under Category 3. They were allowed a minimum weight back up to 900 kg, but their fuel allowance was slashed to only 2140 litres, effectively 4 hours of racing and neutering the challenge they could provide for the Category 1 cars. Three Porsche entered Category 3. The Porsche Kremer Racing team with experienced Le Mans winners John Nielsen (1990) and Manuel Reuter (1989) joined by Giovanni Lavaggi finished 7th overall and 2nd in the Category 3.
