Porsche is famous for launching a special edition just about every six minutes, and in the late 1980s they launched quite a few for 1988. First off, they created a special edition of the 944 Turbo. The new option M758 “Turbo S” included a new turbocharger with redesigned vanes and a remapped DME which increased boost to a max of 1.82 bar. The resulting M44/52 had 30 more horsepower and 15 lb.ft torque to a max of 247 and 258, respectively. But the “S” package was far more than just more boost, as the cooling system was revised, the clutch and transmission were beefed up with hardened first and second gears.
Brakes were borrowed from the 928 S4 and now measured 12″ in front with four piston aluminum calipers. Wheels were Club Sport 16″ forged, polished and anodized units measuring 7 inches in front and 9 in the rear. Suspension was also beefed up with the M030 package; this included adjustable rebound Koni shocks and adjustable perch coilovers in front. Limited slip differentials (Code 220) were not standard, but a must-select option.
Within the already limited edition S (of which about 1,900 were shipped to the US), there was another special edition. The “Silver Rose” launch cars took all of the special aspects of the M758 S package and added a unique color (Silver Rose Metallic, LM3Z) and a very unique Burgundy Studio Check interior. Outside of the Turbo Cup cars, these very limited original models have become the most desirable of the 944 Turbos:
