1975 Porsche 911 R-Gruppe Outlaw

This 1975 Porsche 911 Carrera “R-Gruppe” outlaw is the result of a perfectly executed vision.  What was just a dream for many years finally became reality, when the second owner since 1981 proposed this project to Kelly Moss Road and Race in 2012.  Pairing up with Rothsport Racing shop, these two master builders have turned this stock 911 into the world-class outlaw you see today.

The restoration began with an immediate disassembly of hardware.  It was then stripped down to bare metal, confirming zero rust and no damage whatsoever.  The 911's original sheet metal was then professionally painted in the car's factory color of Cockney Brown.  Alongside this unique and eye-catching finish, you will find many upgrades such as:

  • Custom front and rear bumpers
  • Front center mount oil cooler
  • Custom ducktail with “Carrera RS” badging
  • Anodized black aluminum trim
  • New sunroof cables and wind deflectors
  • H1 headlights
  • New OEM taillights
  • BBS Motorsport E28 3-piece wheels with magnesium centers

Overall, this exterior stands in show-quality condition.

Inside, you will find a bespoke leather interior that is finished to perfection.  The original 1975 Recaro racing seats were reupholstered along with a new leather dashboard, leather door cards with lightweight RS door pulls, and a new black headliner.  Custom Carrera carpet has been installed along with red seatbelts, OEM seatbelt receivers, aluminum pedal set, MOMO steering wheel, and custom gauge cluster with a 10,000 RPM tachometer.  It is safe to say that no expense was spared on this high-caliber interior.

Replacing the original 2.7L block is a robust 3.6L 993 Varioram engine, which was hand selected and used for greater horsepower and torque.  After being completely re-worked, this engine now produces approximately 315HP (an 80% increase over the cars original motor).  This power is sent to the rear wheels via a rebuilt magnesium-case 915 transmission.  For maximum stopping power, this 911 sports Pagid competition brake pads, upgraded 2-piece aluminum hat floating brake rotors, new mounts, and cross drilled Porsche OEM brake rotors.

Additional engine and transmission upgrades include:

  • Porsche GT gears
  • Quaife limited slip differential
  • Internal gate shifter
  • Shift rod and tower bushings
  • Shift coupler with billet collar
  • Custom exhaust and headers
  • GT3 Cup titanium muffler
  • WEVO engine mounts
  • New air intake
  • New oil tank with level and temp sensors
  • Oil line heat shields
  • Custom wiring harness
  • Bosch motorsports fuel pump


Built for performance, this 911 also highlights a completely reworked suspension system including motion control suspension remote reservoirs with 18-click double adjustable struts and shocks, 19mm raised spindles with competition gussets, 22mm sway bars with billet upper shock tower support, upper mono ball shock mounts, and a TRG shock tower brace.  Additionally, Elephant Racing poly bronze suspension bearings and bushings were added all around with Elephant Racing advanced tech adjustable rear spring plates and their quick-change rear splined hub.  Porsche Turbo tire rods were also added, along with WEVO RARB console rear sway reinforcements, a TRG bump steer kit, and hollow torsion bars (24mm front, 31mm rear).

When completed, the proud owner took the car to five different concours events.  At four regional events, the car took 1st place in the G-body class with a score never lower than 178 out of 180 points.  Recently, this 911 won first in class at the 50th anniversary of Rennfest in Atlanta, GA with a score of 179.8 out of 180 points.

The sale will include the original 2.7L motor, original whale tale spoiler, all books, extensive documentation, photos of the build, and a set of keys. Do not miss your opportunity to own one of the most well built outlaws on the market today.

    Good morning, everyone! Thanks PCARMARKET for posting the video from the Werks show yesterday.

    @Upshift4 is correct that the car began as a real Carrera, and the owner used it in various events during his ownership.

    We are out at Laguna Seca this weekend but we will try to answer as many questions as we can during the event today and tomorrow. We are planning on uploading a driving video and accurate audio. The exhaust note that comes from this car is ferocious.
