1988 Porsche 930 Turbo Coupe

The Porsche 930 Turbo was the brand’s first foray into forced-induction road cars and became an icon in the process. Recognizable by its large “tea-tray” decklid spoiler and swollen rear arches, the 930 offered performance on-par or better than contemporary Italian exotics, but with the practicality and dependability Porsche is known for. The turbocharged wallop of power seemingly came in all at once which proved for an exciting drive and earned the car the nickname of “widowmaker” in its prime. A benefit of the Turbo is also the promise of additional power with just a few simple parts – or a lot more when fully built.

This 1988 Porsche 930 Turbo is finished in Guards Red and benefits from a host of both mechanical and body modifications. On the exterior, changes include a new, integrated 964-style front bumper, which is paired with a matching rear bumper and 993 GT2-Style engine lid. The car sits lower than stock on a set of 5-spoke Fikse wheels which are painted black which goes with the Red/Black color scheme of the car. Sitting behind the Fikse wheels are a set of upgraded brakes with red calipers and drilled rotors.

On the interior, the black and red theme continues with custom-upholstered seats with black outers and red centers, finished in German leather. A red lower center console has been fitted, and a red and black Momo shift knob sits atop the shift lever. The steering wheel is also from Momo and it’s a simple 3-spoke Prototipo-style with a dish to it which, when paired with a new wheel-hub, brings the steering wheel closer to the driver. In the center console, a pair of gauges have been added – one for boost pressure, and the other for air-fuel ratio.

The 3.3-liter turbocharged flat-6 was completely rebuilt and converted from Bosch CIS to electronic fuel injection and tuned by EFI 930 specialists Turbo Craft of Phoenix, AZ in April 2015. Using an Electromotive Tec GT engine management system with crank-fire ignition and new Siemens injectors, the car runs smooth, and boosts more progressively thanks in part to the new Precision billet wheel ball bearing turbocharger. New Billy Boat headers and heat exchangers were fitted with a pair of custom 46mm Tial wastegates, and a full custom exhaust out the back. To keep the charge air cool, a custom larger intercooler was also fitted atop the engine with the ends matched to the car’s exterior color. Dyno sheets indicate a frankly astonishing 480 horsepower and 460 lb-ft of torque – when you consider the original car had just over 270 hp, this car is a monster. Another massive addition is the installation of a G50 5-speed manual transmission in place of the standard 4-speed unit. With improved shift feel and better ratios, the G50 was only available from Porsche in the 1989 930 and comes at a significant premium.

If you have always loved the look of the Porsche 930, but felt like the performance just wasn’t quite enough for you, this fully built Turbo would very likely change that. A truly thrilling car, this EFI-converted 930 is set up to be enjoyed flat out and looks like nothing else on the road.
