Porsche 911 R-Gruppe ST/R

This is an R-Gruppe-style 911 built on a 1969 F-series long-wheelbase shell. It is a period-correct "of era" road and track car rather than a backdate or a typical restomod. It was originally a US-market car, was imported into the Netherlands, and was built there by Garage Gmund for an R-Gruppe member. The car is known as "Olive" for its dark green paint.

Power comes from a 3.0-litre mechanical fuel-injection flat-six built by Mittelmotor, with forged rods, titanium springs, high-lift cams and a custom MFI system. After dyno setting at Kremer it is quoted at 335 bhp, with a self-imposed 8,000rpm limit. An RSR-spec header and exhaust, a freshly rebuilt 915 five-speed gearbox and Bilstein RSR-style coilovers replace the original torsion bars. The brakes have been replaced and upgraded, and the underside has been stripped and powder coated.

Details include ST-style steel wings over 8 and 9 inch Fuchs wheels, NACA ducts in the rear quarter windows, Recaro seats, Schroth harnesses and a roll cage. The cabin has no sound deadening. It has covered 7,603 miles, came to the UK in 2023, and has a history file with the engine's correspondence and invoices.
