1980 Porsche 924 Turbo ‘Holbert Racing’ Widebody

An impressively modified example of Porsche’s well-balanced transaxle sportscar.    –     Fitted with Holbert Racing widebody kit in 1983, with Martini Racing-inspired side graphics.    –    Equipped from the factory with desirable Sport Group Package, option code 471.     –    Rides on rare, three-piece BBS wheels.     –    Previously owned by two different, longtime PCA members; acquired by Magnus Walker in 2016

My 1980 924 Al Holbert widebody Turbo is really, really a special car. It was originally delivered to Herman Miller Porsche in New Jersey on 31 July 1980. In 1983, the Al Holbert widebody kit was put on the car, also in New Jersey. You gotta remember, Al Holbert was a Porsche factory driver, racer, and dealer—raced at Le Mans, had his own dealership, and in the early eighties was offering his own version of a widebody fiberglass conversion for the 924 Turbo, based around the 1980 Le Mans racing 924 GTP. This is 45 years ago—way, way, way ahead of its time.
I acquired this very, very special, unique car 10 years ago in 2016 from the third owner. It’s actually rolling on a set of very rare three-piece BBS wheels that are nine inches on the front and 11 inches on the rear. Added to that, the racing Martini stripe that goes down the side and the very, very cool interior makes this truly a very, very special car.

The vehicle in detail

This intriguing transaxle Porsche features distinctive, super-wide fiberglass bodywork by Holbert Racing of Warrington, Pennsylvania. Al Holbert competed in IndyCar, SCCA, NASCAR, and IMSA, and his father opened one of the country’s first authorized Porsche dealerships in Warrington. Besides running his own team, Holbert headed Porsche North America’s Motorsports Division for a time and clinched back-to-back IMSA GTP championships in 1985 and 1986 with a Lowenbrau-sponsored Porsche 962, as well as overall victories at the 1986 and 1987 24 Hours of Le Mans in a Rothmans-sponsored 962—to name just a few of his many impressive wins.
The 924 offered here completed production on 1 January 1980, slated for sale in the United States. It left the factory finished in Alpine White with a black partial leather interior and the highly sought-after Sport Group Package (option code 471) which included ventilated brake discs, larger anti-roll bars, and Koni shock absorbers. Other factory options included a limited-slip differential, rear wiper, electric aerial, four speakers, rear spoiler, and alarm system.
The Holbert Racing widebody kit was reportedly installed in 1983 by Paterek Brothers Inc. in Chatham, New Jersey, for its original owner, a longtime Porsche Club of America member who is said to have retained the car until 2000. The next owner is understood to have kept it for a few years before selling it to the previous owner, another longtime PCA member who showed the 924 at local club events and modified its 2.0-liter inline-four with a Carrera GT-spec 6.10 K26 turbo and other components. Further carefully considered performance additions included an Audi 5000 large-throat throttle body, PWR air-water intercooler, an aftermarket oil cooler, and a Billy Boat B&B stainless steel cat-back exhaust. After adding about 7,000 miles during his ownership, the previous owner sold the car to Magnus Walker in 2016.
Among this unique Porsche’s many interesting features—besides the obvious widebody kit and BBS wheels—are its manual sport seats with period-correct tartan inserts, Mario Andretti signature edition Momo steering wheel, gauges with green markings, and an in-cabin turbo-boost controller. With a bit more of a performance edge than a typical transaxle Porsche, and the looks to match, this would make for a stellar track-day ride or a canyon-carver.
