1975 Porsche 911 2.7 S/T Recreation

This competition-prepared Porsche has been altered to look like a lightweight 911 S/T. The main giveaway, other than the extended arches, are the miss-match of Fuchs front and Minilite rear wheels, which is deliberate, as it was a common S/T mix, as factory nine-inch Fuchs rims weren’t available until 1970.

The base car, in this instance, is a 1975 911 S. As there was no accepted S/T specification for these lesser-known racing variants – merely lightweight takes on production 911 S models anyway – it makes for a relatively straightforward conversion, and one that’s a little more unusual than the far more common Carrera RSR or Turbo clones.

Since its conversion, this 911 seems to have been used for regularity runs, although it appears to have been modified with far more serious rallying in mind. There are the usual safety systems, including a full roll cage, with removeable door bars and Sparco bucket seats and five-point harnesses. In addition, there are the customary fire extinguisher and battery cut-offs on the scuttle. 

Although the vendor, Classic Cars Andorra, is a Porsche specialist situated in the picturesque Pyrenees principality, the car’s modest history file shows that it spent time over the border in Barcelona, where much of its motorsport transformation work was apparently carried out.

As a competition-converted car, this 911 comes with all the associated paraphernalia expected, including additional lights and clearly signposted towing points. There is also a matt black bonnet and engine lid, to reduce glare, and some seriously sticky and wide tyres in the form of Federal RS-Rs up front and Toyo Proxes R888s out back. Both sets of wheels look in good order, with just a few minor marks to their lips to report.

It’s hard to really assess, without seeing the car in the metal, but it appears that the offside sill has taken a small bump around its jacking point. A tighter gap to the bottom rear of the door likewise seems to back this up. We did also see what appeared to be some very mild bubbling to the nearside sill. The paint and panels generally present very well, however, as this is a competition machine, we were in no way surprised to see the odd scratch and chip here and there; for instance the touched-up chip to trailing edge of the nearside rear wing.

The cabin of this 911 has been extensively stripped out, with the factory cloth and comfort replaced by far more serious racing environs. As mentioned already, the first hurdle to entry is the roll cage, but then there are also Sparco Evo buckets to squeeze yourself down into, before buckling up the five-point OMP harnesses. Factory instrumentation has been bolstered by the addition of chrome switch panels, alloy pedals and footrests, the latter also coming courtesy of OMP.

The suede effect steering wheel has GT2i etched on its central boss and is of a far deeper and smaller style than that which came in period from Zuffenhausen. There are two fire extinguishers on passenger side, as well as a hammer for breaking the glass and a shovel, presumably for digging out the wheels from snow/sand. There are a few concessions to practicality in here with a small sunglasses-sized cubby on the passenger side and an additional 12v/USB outlet. There’s also a small stowage box on the rear seat plinth.

According to the vendor, the engine fitted to this Porsche is a 2994cc unit fed by Bosch K-Jetronic fuel injection, but beyond that, we lack any additional information. We could see from the images that the factory air box has been drilled (top) and that the oil filter looks new.

A chassis brace has been added across the front suspension towers and the spare wheel well and fuel tank appeared to be free of accident damage or corrosion, though we weren’t afforded a good view of this area or any of the underside in general. 

This Porsche carries the chassis number 911 5 300170, which designates it as a 1975-built 911 S coupe. The history to accompany the car is far from extensive, yet we do have some important paperwork from Spain. The Ministerio De Industria – Ministry of Industry in Barcelona – seems to have carried out inspections on the car from 1993 to 2000. There’s also some FIA paperwork to accompany the car’s entry in a regularity rally, though this clearly states that it’s ‘no guarantee of the car’s authenticity.’

Work to convert the car to its current motorsport specification appears to be traced to Nou Onze, a Porsche specialist based in Barcelona. The paperwork from said firm seemingly certifying as follows; modifications listed below made to the Porsche 911S vehicle – frame 9115300170 for competition. 

• Shock absorber head holding bar installation forwards.

• Installation of 6-point roll cage.

• Installation of four long range lights.

• Installation of supplementary fog lights – sim30-06 h4:

• Installation of metal brake hose.

• Installation of backet seats – Sparco Evo Plus.

• Installation of 6-point harness type seat belt – OMP.

• Installation of safety fuel tank in the trunk with external access on the front hood.

As a machine capable of classic competition, this 911 appears to have been prepared to a good standard. Whether you plan to remove the motorsport amendments or keep them and enjoy some classic events, this 911 should have you covered regardless. We estimate that it will sell for €70,000 - €90,000.
