Motorsport Mondays: 1974 Porsche 911 “RSR”

About two weeks ago, I wrote up two ex-Turbo 911 racers that took the builds in different directions; one, an ultimate street car with track potential and a crazy V8 LS7 swap, and the other a more traditional RSR-inspired PCA club racer. Well, today we’re back at it with another ex-930 that has been converted to more traditional RSR style, with a big IROC whale tail and some pretty trick Jongbloed wheels, along with some Skoal Bandit/Group 44 inspired decals. What do you think?

The car was built on an original 930 Turbo chassis, Chassis #9307800170, by Bob Johnson of Minneapolis, MN to 1974 RSR specifications as follows:

3.3 litre engine with 100mm bore and 70.4 stroke, twin plug heads, Carillo rods, Mahle pistons, 46mm downdraft Webers, and 340 horsepower
915 gearbox
limited slip rear
924 S4 calipers

Set of 8 and 9 x 16 Fuchs alloys
74 RSR-style whale tail
3.8 RSR style hgh wing
Body is in fiberglass except for steel doors, rear fenders but fiberglass flares

The former owner had the car built for over $100,000 plus the cost of the car. It is very well sorted and was mechanically freshened by Bob Johnson, including complete engine rebuild with no more than 30 minutes on fresh engine. The car is very fast, well balanced, and safe because of the substantial roll cage. Brian Redman said this was one of the most well balanced 911s he has ever driven. It has been extremely reliable, as it has finished every practice session and race ever entered.

Ready to race. All it needs is a set of tires, fuel and a new owner.

While the look of this car is certainly enough to grab my attention, I have to admit I was also immediately drawn to the Jaguar XJR-9 in the background. It’s just not often that you see those cats in the wild – but I’m sure it’s another story for a different day. The build on this car looks solid and well executed – a quick vin check seems to indicate it was originally a 1975 3.0 930. It’s not over the top, and frankly if you could get into a vintage event in the car it would be difficult to tell it apart from some of the real original racers in many respects. I particularly love the Jongbloed wheels; they can be had in either magnesium or aluminum, but odds are on this set the builder went with magnesium. That said, the car also comes with more traditional and equally valuable Fuchs wheels. The graphics may not be to everyone’s taste, but I think they really work on this application and look classy; the car really appears as if it could have been vintage correct. As a turn key 911 vintage racer, you won’t get much better quality than what’s here for less money – the reserve is still on but bidding is below $30,000 as of writing. If it stays under $40,000, I’d suggest this car is a steal and will make the new owner very happy for some time to come.
