In 1993, the 3.3-litre engine 964 Turbo, which had been available since 1990, was enhanced with the installation of the long-awaited 3.6-litre turbocharged M64 engine. Power output was raised from 320 bhp to 381 bhp, turbo lag was reduced and the 0–60 mph benchmark dropped from 5.0 seconds to 4.6. At the same time, Porsche tweaked other areas of the car by upgrading the braking setup, lowering the suspension by 20 millimetres and adding a Carrera RS rear axle and matching rear bumper. Eighteen-inch, three-piece Speedline by Porsche alloys rounded off the new package.

Due to the impending arrival of the 993, the 3.6-litre turbocharged variant of the 964 was available for just one year from 1993 to 1994. A mere 1,437 examples were sold, vastly undercutting the 3,660 964 Turbo 3.3s that had been built from 1990 to 1992. Perhaps more significant though is that, of the 1,427 examples, just 159 were built in right-hand drive. It is as much rarity as it is engineering purity and build quality that makes the 964 Turbo, especially in 3.6-litre guise, such a prized asset for any collection.

Originally ordered via Porsche South Africa by the Sultan of Brunei and exported to his home country as part of the Sultan’s lavish car collection, this particular right-hand-drive 3.6-litre 964 Turbo covered just over 1,500 miles before being placed into storage. It was recently rescued by its current owner and imported directly to the UK, whereupon the car was subject to a far-reaching re-commission at a leading specialist. The engine has been removed, rebuilt and retuned; the suspension and drivetrain has been dismantled; and all perished components have been replaced, with particular attention to hoses, gaskets and rubber elements. Finally, the car has been subjected to a 111-point check by Porsche GB.

Painted in suitably eye-catching Guards Red and specified with recoil bumpers, sunroof and trimmed in black leather, it has now covered less than 1,700 miles. It is perhaps the lowest mileage, privately owned 3.6-litre 964 Turbo in existence and presents beautifully throughout. Supplied with a fresh MOT, Porsche Certificate of Authenticity (which confirms that the car retains its matching-numbers engine) and Porsche Vehicle Identification sheet, this is an acquisition opportunity unlikely to be repeated.
