In 1972, at the behest of Dr. Ernst Fuhrmann, Porsche’s long-time head of Engineering, Porsche initiated a program to feature the 911 as a veritable race car in order to emphasize the model’s sports-car capabilities and move away from developing concept race cars. This “win on Sunday, sell on Monday” strategy has been widely used by several sports car manufactures.
Based on a 911S chassis, Porsche added wider steel flares front and rear, a massaged 2.8 flat six, uprated brakes, wider tires, and the iconic duck tail spoiler for the express purpose of campaigning the 911 RSR in 1973. Porsche would build a total of 49 cars and as a factory-built race car, it was the first 911 to break the 300 hp barrier.
The successful RSR model eventually went on to win the overall 24 Hours of Daytona, IMSA Carmel GT, and SCCA Trans-Am titles that year. Needless to say, it was a rousing success. Unfortunately, Porsche never produced a road-legal version, thus car enthusiasts were left to their own devices and build their own.
Which is what the owner of our featured 1970 911 did. This RSR tribute was professionally built by Deutsche Motor Sports in Concord CA and benefited from a bare-metal restoration complete with welded steel flares, a fresh coat of Grand Prix white paint, and numerous exterior and interior modifications. Just the way the factory would have built it…for a lot less money.
If you are looking for an authentic longhood RSR with the right combination of performance modifications while maintaining its classic Porsche heritage, this RSR may be the one for you. This is a turn-key car ready to rumble at the local weekend race track near you and currently offered on Pelican Parts for $60,000.

I’ve had “For Sale” and now “Available” on the quarter windows for a while and its now time to get serious about finding a new owner for my completed project. A GT3 is on my bucket list and I’m not getting any younger.
