The RSR moniker was first used in 1973 when a competition Porsche 911 was fitted with a normally aspirated 2.8-litre engine, upgraded brakes, modified suspension, and lightweight bodywork and intended to compete in the FIA’s Group 4 category. The 3 digit RSR designation was established and therefore used for Porsches most extreme cars destined for the race track and competition from then on.
The following year, a new three-litre RSR was developed, and would go on to dominate GT competition for nearly a decade.
A new RSR model was unveiled in 1993. It was based on the updated 964 series and powered by a 3.8-litre engine. Weight-saving features and chassis improvements were implemented, helping the 964 3.8 RSR achieve incredible success in international endurance and GT racing.
In 1996, the Cup 3.8 RSR was introduced, and were based on the 993 Carrera Cup chassis (code M001) and equipped with a specially prepared racing-specification 3.8-litre engine. These were true factory-built race cars, with their specifications and design inspired by the 993 Carrera Cup and GT2 models.
They featured front and rear spoilers, riveted GRP arch extensions, large centre-lock BBS wheels, and a stripped, race-ready cockpit. Three distinct 3.8-litre engines were made available for the RSR, The M64/70 Cup racing engine, M64/75 Engine for Endurance racing and the IMSA-spec M64/80 engine. The gearbox was a specially designed G50/34 close ratio six speed.

This jaw dropping Glacier white RSR is 1 of 45 factory built race cars. Sporting bolt on arches, huge wings, bonnet and boot pins, air jacks and a bonnet cut out for the endurance spec fuel tank it’s obvious this isn’t a standard 993 or RS.
Having been campaigned sporadically as a second car for Gentleman drivers this factory built race car has covered minimal mileage, it has remained accident free and still wears all of its original panels and factory produced numbered shell as it did when it left the factory, never crashed or altered.
With just one seat, no sound deadening and a matter roll cage the interior is extreme and built only for the race essentials. Air jacks are standard fit along with a fuel reserve light and the race programmed Motronic ECU behind the drivers seat.
As with all Porsche built race cars the Rev counter is turned on its side for a clear view of the climbing needle to the red line with further indicators on this car to protect any over revs with shift lights and a sticker. In addition a 993 handbrake lever and cables have been fitted for road regulations.
ENGINE & TRANSMISSION
The M64/75 Type 3.8 RSR engine is an extensively reworked race-bred engine with stronger, lighter valve gear, rockers, high-lift cams and special pistons and barrels. To maximise performance, the inlet plenum and exhaust manifolds are also thoroughly revised and mated to six individual throttle bodies.
Power is delivered through a single-mass flywheel to a unique RSR six-speed Type G50/34 manual box.
As one of the most powerful naturally aspirated air-cooled engines built by the factory the noise and driving experience is addictive to say the least.
Run in period by a well respected and successful race team, serviced and inspected on arrival in the UK and again in house, the mechanical condition remains in excellent health.
WHEELS, TYRES & BRAKES
The centre lock 18 inch RSR wheels are finished in gold and present in excellent order. Tyres are courtesy of Michelin Pilot sport tyres N rated and matching all round with large amounts of tread.
The braking system is factory fit Brembo calipers front and rear finished in red and clamped to huge drilled discs all round.
As confirmed by the original purchase invoice still present in the history file this RSR was ordered by 910 Corporation in January 1997 at the cost of nearly 240,000 Deutsche Marks.
Delivered and imported to Japan in March 1997 it was successfully campaigned from 1997 to 1999 in the GT300 category in the Japan Grand Touring Car championship (JGTC). Racing at Suzuka, Fuji, Sports Land Sugo and Sendai Highland Raceway.
Running two categories, GT300 and GT500 the JGTC is one of the most popular and biggest race series in Japan and is still in action today renamed the Super GT with F1 drivers and serious machinery racing for fame and glory.
With a complete record of its entries online and available, this RSR raced as car no.911 as the Ninten TIB Porsche (1997), Ninten PCJ Porsche (1998) and the Diamond Porsche (1999).
Imported into the UK in 2017 by famed Porsche collectors and enthusiasts it is road registered for the ultimate air-cooled driving experience. The history file contains the original purchase invoice, period Japanese import document, Porsche dating letter (confirming build date, engine and transmission numbers), race history printouts and period pictures along with the spare key.
