For those looking for a significantly up-rated 930 Turbo, Porsche Stuttgart and a handful of Porsche importers could offer just that through the fitment of a ‘Group B’ package. These were modified for greater performance and consisted of a larger oil cooler, intercooler and turbocharger. A driver-adjustable boost control from a 935 was installed, and cylinder heads with lower compression were fitted to accommodate the increase in boost. The only external clue that this was not a stock Turbo was the RS/RSR-style oil radiator in the front valance. This Group B kit was only available from the factory or via Porsche/VAG-owned importers due to the extensive modifications required.

This example was imported and modified by Porsche’s Swedish distributor, VAG, and was first delivered on 15 January 1988 through Porsche Stockholm. It is known to have had two previous private owners before coming into the hands of the consignor. Finished in Guards Red over black leather, it is equipped with standard Turbo fare, including wider wheels and tires under dramatically flared fenders, a rear ‘Whale-tail’ spoiler, an electric sunroof, power-adjustable sport seats, electric windows, a rear wiper, headlamp washers, fog lamps, security system and automatic climate-control.

Supplied with all its original manuals and service books, air compressor, spare key and a mint tool kit, this handsome Turbo shows less than 42,000 km on its odometer. Amazingly, the majority of the paintwork on the car is original, with the exception of the left-hand door and rear fender, which as been repainted. Even the original invitation to join the Porsche Owners’ Club of Sweden remains incomplete in the service book. Only 677 J-Program Turbos were produced for ‘Rest-of-the-World’ customers; this is among the more unusual and certainly among the most rapid.
