A prolific collector of fine automobiles, Mansour Ojjeh was ideally placed to secure for himself from Porsche a specially modified version of the German manufacturer’s ultimate road car: the fearsome 911 Turbo.

Group 4 homologation rules, which required 400 road cars to be built, had spurred the development of Project 930 — the original 911 Turbo. In production from April 1975, the Turbo married a KKK turbocharger to the 3.0-liter RSR engine, a combination which, in road trim, delivered 260 hp for a top speed of approximately 246 km/h (152 mph). The engine was enlarged to 3.3 liters for 1978, gaining an inter-cooler in the process; power increased to 300 hp and the top speed of what was the fastest-accelerating road car of its day went up to around 258 km/h (160 mph).

The 911 Turbo’s raison d’être — the racing 934 and 935 — had pioneered what would come to be known as the Slant or Flat nose, and this new look was soon in demand from 911 customers. Kremer Racing offered a conversion, and this service was later taken up by the factory’s own Customer Department to special order (Sonderwünschen) from 1981, becoming an official option only in 1986. The front wings were steel, incorporating cooling vents and pop-up headlamps (early examples had them in the air dam) while the rears had extra cooling intakes. There were different sills, and along with the body modifications came an even more luxurious interior.

For his own special 911 Turbo, Mansour Ojjeh opted for the 935-type bodywork and an engine tuned to produce 375 hp, an increase of some 25% over standard. Maximum torque went up to a tire-shredding 361 lb/ft. According to the Porsche specification sheets on file, the result was a top speed of approximately 285 km/h (177 mph) and a 0–100 km/h (0–62 mph) time of 5.2 seconds.

In addition to the 935-type bodywork, the sheets list the following special equipment: roll bar, automatic harness, Recaro seats, wooden dashboard paneling, central locking, lowered suspension, competition shock absorbers and competition stabilizers. Copies of the car’s original factory documentation (on file) refer to it as a “Porsche 911 Turbo Spezial.” Unrestored, but maintained in first-class condition, this unique and historic Porsche 911 Turbo is worthy of the closest inspection.
