1983 Porsche 911 Almeras 3.3 Twin Turbo: A Forgotten Turbo Legend

Twin-Turbo Legacy - In the world of performance cars, certain machines represent more than speed—they capture a moment when engineering ambition and creative experimentation collide. During the early 1980s, turbocharging was still evolving from a racing innovation into a road-going technology, and manufacturers were learning how far they could push it. Against that backdrop, the unique 1983 Porsche 911 Almeras 3.3 Liter Twin Turbo emerged as an intriguing chapter in the ongoing story of the 911, transforming an already formidable sports car into something far more daring.

The car’s foundation lies in the legendary Porsche 911 Turbo (930), a model that introduced the “Turbo” nameplate as the pinnacle of performance in the 911 lineup. By the late 1970s, the 3.3-liter version of the turbocharged flat-six engine produced around 300 horsepower with the help of a single turbocharger and an air-to-air intercooler. It was fast, raw, and demanding to drive, embodying the spirited engineering philosophy of Porsche. Yet for some enthusiasts and tuners, even that impressive setup left room for further experimentation—particularly in how the engine delivered its power.

That curiosity found a home in the workshops of Almeras Frères, a French racing and tuning specialist known for pushing Porsche platforms beyond factory boundaries. Building upon the 1983 Turbo’s mechanical base, the Almeras team replaced the original single turbo configuration with a twin-turbo system sourced through KKK. The upgrade was paired with a racing-inspired fuel injection system derived from the Porsche 934 competition car, turning the road-going 911 into a machine that carried genuine motorsport DNA beneath its rear decklid.

Inside the engine, Almeras engineers introduced a series of meticulous refinements rather than radical structural changes. The valve system remained largely standard, preserving reliability, while specially designed camshafts allowed for greater valve opening to enhance airflow. Custom pistons were engineered to reduce friction and withstand the elevated pressures produced by the twin-turbo arrangement. To ensure durability under intense operating conditions, the engine was carefully balanced and equipped with an additional oil pump that extracted oil from the turbochargers when they shut down—an elegant solution that helped protect the system during heat cycles.

All of these upgrades dramatically altered the car’s performance character. Power climbed to roughly 440 horsepower, a remarkable figure for a road-legal Porsche in 1983. With that output, the modified 911 could reach a top speed of about 291 km/h, placing it among the fastest machines of its era. The car itself has since undergone a thorough restoration carried out by modern technicians at Almeras, bringing its mechanical condition up to contemporary standards while respecting its original identity. Fresh Pirelli P Zero tires, a new clutch, an updated braking system—replacing an earlier setup derived from the Porsche 917 race car—and a modernized engine control system all contribute to keeping the classic performer alive on today’s roads.

Visually, the Almeras Twin Turbo retains the unmistakable silhouette of the 930 generation: wide rear fenders, the iconic whale-tail spoiler, and the purposeful stance that made the turbocharged 911 instantly recognizable. Inside, the cabin remains largely faithful to the period, combining driver-focused ergonomics with the understated luxury typical of Porsche interiors in the early 1980s. The result is a machine that looks authentic to its time while hiding a far more aggressive personality beneath the surface.

This rare creation also belongs to a broader culture of ambitious Porsche tuners who reshaped the brand’s reputation during that decade. Companies such as Gemballa with its dramatic Avalanche and Mirage builds, and RUF Automobile with the legendary RUF BTR, demonstrated just how versatile the 911 platform could be. Within that landscape, the Almeras 3.3 Liter Twin Turbo stands out as a distinctive experiment—an example of how independent engineering passion could transform an already iconic sports car into something even more extraordinary. *** [EKA | FROM VARIOUS SOURCES | GTSPIRIT | BRINGATRAILER ]
