I all!

I'm writing an article for an Italian magazine and i'm looking for some information about a rare "Homologation '76 Carrera 2.7". Someone call them RS, they were produced as European racing homologation special, with the glorious 210 HP 2,7 litres. Probably 123 of them were produced.
Does anybody know if and where they actually raced?
Does anyone know about this VIN range 9116609001-9116609123 and Targa 9116619001-9116619030?

Thank you in advance!

I thought that by 1976, Porsche was using the 3.0, 255 HP engine, not the 2.7, 210 HP, in their RS models.

But I'm sure there's someone out there with more Porsche history knowledge than I.

Sure! Carrera 3.0 or "Carrera 3" was top of the line in '76, but i read somewhere there was a batch of mechanical fuel injection (MFI) 2.7 Carrera. It was a limited production for homologation purposes, just to allow racers (maybe in Group 3 ?) to perform a better tuning than K-Jetronic engines.
I think these cars (123 coupé and 30 targa) are pretty rare and unknown; is there a Porsche historian out here...?

Thanks in advance!

Those cars are a mystery to me.

Post the question on the Pelican Parts site or Early 911S Registry site. Many more Porsche historians to be found there than here.

Good luck!

Gemini

Ok!
Thank you SandyI

I recall reading in Road and Track about a 1975-76 Carrera RS that sported the "turbo flares" and a high compression 3.0l. Not to be confused with the "regular" 3.0l Carrera available in Europe (US only got 2.7L cars till the SC was introduced in 1978.) Glad this only confuses the issue

Confusion is the beginning of knowledge...

From 1974 to 1976 there was the Euro Carrera 2.7, with the same engine and gearbox etc as the 1973 Carrera RS 2.7, but with the looks of the "bumper cars". Only a small number of cars were built as 1976 models, could be 155, before it was replaced by the Euro Carrera 3.0.

I haven't read anything about it being for homologation purposes though...

Kind regards,
Tommy

Carrera RS (1973 and 1974)



A 1973 Porsche 911 Carrera RS
These models, valued by collectors, are considered by many to be the greatest classic 911s all-time. RS stands for Rennsport in German, meaning "racing sport". The Carrera name was reintroduced from the 356 Carrera which had itself been named after Porsche's victories in the Carrera Panamericana races in Mexico in the 1950s. The RS was built so that Porsche could enter racing formulae that demanded that a certain minimum number of production cars were made. Compared with a standard 911S, the Carrera 2.7 RS had a larger engine (2687 cc) developing 210 PS (150 kW; 210 hp) with MFI, revised and stiffened suspension, a "ducktail" rear spoiler, larger brakes, wider rear wheels and rear wings. In RS Touring form it weighed 1075 kg (2370 lb), in Sport Lightweight form it was about 100 kg (220 lb) lighter, the saving coming from the thin-gauge steel used for parts of the bodyshell and also the use of thinner glass. In total, 1580 were made, comfortably exceeding the 500 that had to be made to qualify for the vital FIA Group 4 class. 49 Carrera RS cars were built with 2808 cc engines producing 300 PS (221 kW).
In 1974, Porsche created the Carrera RS 3.0 with K-Jetronic Bosch fuel injection producing 230 PS (169 kW).It was almost twice as expensive as the 2.7 RS but offered a fair amount of racing capability for that price. The chassis was largely similar to that of the 1973 Carrera RSR and the brake system was from the Porsche 917. The use of thin metal plate panels and a spartan interior enabled the shipping weight to be reduced to around 900 kg (1984 lb).

1976 Porsche 911 2.7
The Carrera RSR 3.0 and Carrera RSR Turbo (its 2.1 L engine due to a 1.4x equivalency formula) were made in tiny numbers for racing. The turbo car came second at the 24 Hours of Le Mans in 1974, a significant event in that its engine would form the basis of many future Porsche attempts in sportscar racing, and can be regarded as the start of its commitment to turbocharging.
[edit]2.7-litre / G, H, I and J series (1974–1977) The new impact bumper

MY 1974 was the introduction of impact bumpers to conform with low speed protection requirements of US law, these bumpers being so successfully integrated into the design that they remained unchanged for 15 years, MY 1989. The engine size was increased to 2687 cc giving an increase in torque. The use of K-Jetronic CIS Bosch fuel injection in two of the three models in the line up— the 911 and 911S models, retaining the narrow rear wings of the old 2.4, now had a detuned version of the RS engine producing 150 and 175 PS (110 and 129 kW) respectively.
[edit]Carrera 2.7 / G and H(1974-1975)
The Carrera 2.7, now a regular production model, inherited the wider rear wings of the RS together with its 210 PS (154 kW) MFI engine and was indeed mechanically identical to the 1973 RS and still weighed the same at 1075 kg (2370 lb). All three models were given high backed front seats.

The 74-77 Carrera's built the type 911/83 motors are not RS's. They are great cars however and until about 5 years ago were fairly inexpensive. They were not built to homologate anything but to consume an existing stock of 911/83 engines. There is a lot in that wikipedia post that is not correct.

OMG, yes.

Hello Jochen,

Just come across your enquiry. Your Targa is the last of 20 supplied to the Belgian Gendarmerie in 1976 with VINs 9116619011 to 9116619030. (The numbers 1-10 were not used) The cars had a narrow body rather than the Carrera rear flares and the 911/83 engine. Would like to see some pictures of your rare Porsche if you are able to post .
