Was there a G-series 2.7 RS?

[dd74]

In the latest 911 & Porsche World magazine, there is a photo of a green 1974 Porsche Carrera on a racetrack. The caption, however, calls the car an "RS Carrera."

I know there was a limited run of 3.0 RS Carreras with flared arches all around, and there was a '74-'75 Carrera before the Carrera 3.0 arrived. But was there ever an RS version of the '74-'75 Carreras? I'm assuming if there was, it'd be a ROW car.

Thanks.

There was a '74 Carrera RS (not sure about 75). I think it has the exact same engine as the '73. They go for about 1/3 the price.

So the Euro '74 Carrera with the 2.7 MFI was known as the RS, while the U.S. CIS version was known just as the Carrera? Hmmm...

Hmmm I may be wrong there. The only reference to a 74 Carrera RS I can find online is the 3.0.
I guess the 74 Euro Carrera had the 2.7 mfi?
This Carrera business is all terribly confusing. Occasionally a non p-car friend will ask me what the 'Carrera' designation really means, but its been used so many times for so many vastly different models that its really impossible to explain to a layperson. Most people think a/ it means coupe (as opposed to targa or cab) or b/ its applicable to any 911- basically the 2 terms are interchangeable.

There was no 1974 Carrera 2.7 RS

The 1974 Carrera RS was the 3.0 RS, fitted with a similar spec motor to the 73 2.8 RS motor. It has "turbo" style arches



I have a 1974 2.7 Carrera. The Euro spec car had a 911/83 mechanical injection motor which is virtually identical to the 73 2.7 RS motor apart from the oil sender placement. The US spec car had a 2.7 CIS motor producing 175 bhp and was identical to the US 2.7 911S apart from the flared rear arches and slihtly higher specs.

There was a very unique run of 123 cars for the 1976 model year that are designated 'Carrera RS'. They too have the 911/83 motor the same as the '73 Carrera RS. Check out this Rennlist thread. A very nice example of one of these cars is shown and talked about in detail.

Very interesting! Thanks for the info.
What an interesting run of very obscure cars!

Interesting back story about the 3.0 RS and why the 2.7 RS was produced. The one problem I have with the Rennlist thread is the 3.0 RS never came with K-jet injection. It was supplied with Kugelfischer (sp?) MFI. So that argument about the 2.7 RS being needed to make that year's touring group competitive, doesn't hold up.

Unless, of course, the Kugelfischer was a poor induction system.

Brian, are you sure they designated those 76's as RS? Boschen and Barth's book and the cars we've seen had them pegged as Carrera 3.0's (I know small crank end 3.0 cis motors were the norm on the 3.0) even though the 2.7 mfi was installed

I dunno. What you define (TRE) sounds like a mishmash of leftover parts at best, denoting a factory bastard. Could that be the case? Would Porsche knowingly mix up pieces and parts with their cars and still call them Carrera 3.0s? I've always assumed the C3 was a CIS-engined car.

Lother Boschen and Jurgen Barth's "The Porsche Book" lists a 1976 model:

Coupe: 9116609001 - 9116609123; qty 123
Targa: 9116609001 - 9116609030; qty 30

With engine numbers: 6668001 - 6668155
Engine code 911/83

"Special model fitted with 210bhp engine"

Anybody seen a targa version?

The '76 C3 w/cis & al. block was a 930/02 w/ engine serial #666 0001>

The '76 RS w/MFI & mg blockwas 911/83 also w/ engine serial #666 8001>


How's that for confusing?

Bill, do you mean:

?

I'm nitpicking everything today, huh? sorry

We always thought that all the C3s were cis as well, till one was imported to the usa. it showed up on our door step because the compliance shop could not figure out what to do with an mfi motor. That's when we did the research: paperwork on the car from yurop was carrera 3.0, matching numbers, perfect as done at the factory installation of the mfi 2.7. It was the B+B book that told us it was a real deal. Is it a bastard? NO! its a cool car with more suds than the 3.0 cis. (Though this particular example got a SC 3.0 so it could pass smog)

Its too bad olaf lang is no longer with us, we could have found out Porsche's reasoning farily quickly. I can only assume it was an attempt to keep the model homologated for competition in some fia class.

Left over parts theory: Motors don't just hang around at Porsche in those kind of numbers, they would sell off left over stuff quickly (just stroll thru Stoddard, Sutterfield's, and Vasek's warehouses years ago - filled with "obsolete" parts and cars!)

No I mean what I originally posted.

Dave the C3 wasn't an RS3.0 was it? or the oh so similar 2.7RS that I posted above?

[TRE Cup]

hi bill
no, the car was badged and titled in yurop as a carrera 3.0. rs 3.0 was a totally different car (which i foolishly sold away some years ago!)

[Bill Verburg]

Yeah I remember your RS3.0, I think I even have a pic or 2 somewhere around here. When I bought my C3 that was one of 3 cars I was looking at, the other 2 were a 73RS touting and an RS 3.0

I went the street lux route w/ the C3, what a mistake.


If you read my post above the 2.7RS MFI 911/83 and 3.0 cis 930/02 use the same initial engine serial # 666 the difference is in the final sequential #s

I have fairly complete records for all those cars. The only 3 liters that I have documentation on are the mfi RS 3.0 and mfi SC/RS 3.0

[dd74]

Okay - aside from the Rennlist photos, which are slightly suspect only because who would put a sunroof in their very rare (123 copies) RS 2.7, does anyone else have a photo of this car?

Bill: now that's interesting...I didn't know there was a C3 lux. I've also never seen a C3 road test. Could you upload one? I'd like to see what the car was all about in a test scenario.

Thanks.
