As turbocharged versions of both the 924 and 944 had made it into series production, many Porsche enthusiasts were eagerly anticipating the arrival of a forced induction 968. However, neither the turbocharged 924 or 944 had been a massive commercial success and with the 968's diminishing market share having been tiny by comparison, a series production Turbo just wasn't considered worthwhile. Porsche did build a handful of homologation specials though, the Turbo S having been in the same vein as 1981's 924 Carrera GTS. Only 14 were built between 1993 and ’94, all being ordered through Porsche’s Customer Sport Department in Weissach.

Based on the critically acclaimed normally aspirated Club Sport, the Turbo S featured firmer springs and dampers plus thicker anti-roll bars, ride-height being dropped by an additional 20mm. The braking system was beefed-up with four-piston alloy calipers and cross-drilled and internally ventilated discs from the 3.6-litre 964 Turbo S. This 964 of the same name also donated 18-inch three-piece cast alloy Speedline Cup Design wheels, these originally being shod with Dunlop Sport 8000 tyres (235/40 ZR 18's to the front and 265/35 ZR 18's at the rear). Clearly the biggest difference between the sublime Club Sport and this brawnier homologation special though was the presence of a solitary KKK turbocharger. To accomodate it, Porsche were forced to ditch the superb Variocam system found on normally aspirated 968's and instead adopted an old eight-valve head from the forced induction 944. Similarities with the 944 Turbo didn’t end there, these new Typ M44/60 engines retaining an identical 8.0:1 compression ratio. Crack DME sequential multi-point fuel-injection brought things right up to date, displacement remaining identical to the engines found in normally aspirated 968's at 2990cc.
