Engine and Performance
The turbocharged twin-plug 3.4-liter gasoline flat-six gives the 1978 Porsche 911SC substantial torque, forceful acceleration, and a far more urgent character than a standard naturally aspirated SC. MoTeC engine management oversees the modified powertrain, supporting precise fuel and ignition control while complementing the dual oil-cooler system. A five-speed G50 manual transaxle places clutch timing, deliberate gear selection, and progressive throttle application at the center of every committed drive. The limited-slip differential distributes torque across the rear axle, supporting traction and more confident corner-exit acceleration when the turbocharged engine comes on boost.
Engineering and Specifications
Bilstein shocks, Elephant Racing torsion bars and quick-change spring plates, JWE adjustable sway bars, raised front spindles, an aluminum strut brace, and polybronze bushings create a comprehensively developed suspension package. Full-floating drilled front rotors work with 930 Turbo brake calipers, providing substantial stopping hardware suited to the increased performance. Staggered 16-inch Fuchs alloy wheels measure seven inches wide at the front and nine inches at the rear, wearing Bridgestone RE-11 tires in 205/55 and 245/45 sizes.
Design and Heritage
The body combines the compact cabin, sloping roofline, rounded front fenders, and rear-engine stance of the classic 911 with a purposeful metal longhood conversion. Slate Gray paint gives the sculpted panels a restrained technical presence, while the 911S-style front bumper, widened rear arches, black-centered Fuchs wheels, and low stance introduce a competition-inspired identity. Inside, orange leather upholstery, Recaro Pole Position seats, concentrated controls, compact instrumentation, and an intimate driving position create a cockpit focused on support, visibility, and direct mechanical engagement.
Driving Experience
From behind the wheel, the 1978 Porsche 911SC should feel compact, immediate, and progressively more intense as the turbocharged flat-six works through the G50 gearbox. Adjustable chassis hardware, wide rear tires, 930 brakes, supportive Recaro seats, and the rear-engine layout create an experience centered on timing, balance, and deliberate control. On winding roads, specialist tours, private performance events, or carefully managed circuit sessions, the Porsche promises tactile shifting, commanding acceleration, decisive braking, and unmistakable air-cooled theatre.
