Gaston Andrey Motorsports has an extensive list of Porsche 2.7 RS Touring and Lightweights for sale. 

The new RS 2.7 was introduced at the 1972 Paris Auto Salon. The new model, branded the Carrera RS, "M471 "Lightweight , "M472" Touring and "M491" RSR was duly homologated with the construction of 500 examples to meet the F.I.A racing class regulations. The cars sold quickly based on the performance for the track. Porsche added a second production run, another group of 500 cars was built and then a third run. Porsche built the RS Touring with more road going features retaining the interior trim and comfort features of the standard 911 S. Porsche built a total of 1,590.  200 Lightweights, 1390 RS Touring and 55 RSR's.

The 200 Porsche 2.7 Lightweights used the 2.4-litre 911S, the quickest 911 at the time, as the basis for the RS. Its air-cooled flat six was bored out to 2,681cc, with 193 bhp to 213hp at 6,300rpm. Torque jumped up too, from 211Nm to 255Nm at 5,100rpm. Porsche made thinner body panels, lighter bumpers and a complete absence of creature comforts. This cut weight to just 975kg in original RS Sport spec models (factory code M471) – usually called Lightweight or RSL. Thinner-gauge Glaverbel glass was exchanged for the regular production glass, while the chassis was upgraded with forged-alloy front-axle supports, reinforced rear-axle trailing arms, and Bilstein gas-pressurized shock absorbers at all four corners.

Porsche dominated the Group 3 and 4 competition during 1973; the Carrera RS 2.7 Sport (or Lightweight) eventually became the basis for Norbert Singer’s highly successful RSR racecars.

The first batch of 500s saw both the RS Sport and RS Touring share lighter-gauge steel roof and door panels. The first RS Touring Coupes made do with just the thinner windshields, although a few received the full set. On the second and third series of cars. Touring models had the standard 911 glass. Touring version was much more civilized and closer to the 911 S in body specification, retaining many parts suitable for normal motoring.The factory options were electric sunroof (M650), electric windows (M651), and an electric antenna/speaker package (M440).


 RSR. The front fenders are widened, the rears flared out even more. The fiberglass front "bumper" becomes a spoiler with a central air intake for the oil cooler.   The front suspension's torsion bars are bigger and three sizes of adjustable front anti-roll bars are available. At the rear, again the torsion bars are bigger; here there's only one size anti-roll bar to be had but it's adjust­able,   Brake discs for the RSR are straight from the 917 Can-Am car—radially vented and cross-drilled—and are applied by the 917's 4-piston calipers.   The Carerra RSR engine   Bore is  another 2 mm to give 2807cc; the compression ratio is raised from 8.5:1 to 10.3:1; the cam timing made as radical as practical for racing use; the fuel injection recalibrated; but the engine retains only one camshaft per bank.
