930 Turbo Carrera

My goal with this car was a total mechanical rebuild with a cosmetic refresh AKA deep cleaning. Here is a nice shot of aged but intact black fender well paint. Also a terrific shot of stock as delivered underside stripped of protective shipping cosmoline.

I'm not sure I follow. Where did we get that #0011 was a 930 prototype or pre-production model? 0011 and beyond are production chassis numbers. Is it because it was an early build? There were already at least three 930 prototypes before 0011 was produced. Is there any documentation that shows 0011 would have been produced before the normal 1975 model year start? I don't think so since one of their true prototypes, the Carrera 2.7 Turbo, was built early in the 1975 model year. IMO, 0011 and beyond are production cars...just early production models with perhaps some unique details. Remember that Porsche changed details about their cars on a weekly basis...things were constantly being changed. Earlier cars will have less of the modifications that were done to later cars.

True prototypes during that time were typically produced on previous model year chassis. Porsche did this for the 1973 Carrera 2.7 (including re-stamping a few chassis numbers into the first 10 reserved numbers from each serial number range). This was done again for the 930 with 1973 911 330 0157 (silver non-working prototype), early 1975 911 560 0042 (silver Carrera 2.7 Turbo), and the black prototype with Austrian hood corner stripe. Similarly, Porsche did this for the 1976 Carrera 3.0 using 1975 Carrera 2.7 MFI chassis numbers.

Porsche always homologated from 0001 since that allowed them the flexibility to "build" a car in the first ten slots, or re-stamp one of their prototypes into that range. As far as I can tell this re-stamping only happened for the 1973 Carrera RS. The RS is the only 1970s model that I could find that actually had a car built within the serial number range of 0001-0010. Does anyone know other examples of pre-0011 chassis numbers that were produced?

 

Where did you find this 930?

 

Perhaps these very early “production” cars were not necessarily prototypes but could have been preproduction models similar to the U.S. ’76 Turbo Carreras, #0011 to #0015 that had unique features such as the Euro bumper tail markers and very early production (August 1975 for U.S. #0014).

GLP 870N, #0012 is unique in that it has a very early build (before the Oct ’74 London Motor Show) and has quite a few unique features from standard RHD production ’75 Turbos (no bumper tail markers, variable boost, and rear wiper on the right side). I don’t know if '75 #0011 has similar features or not since I’ve never seen it documented in print or on the web - so many of these very early ’75 Turbos appear to be dust in the wind.

 

i recall the silver prototype was based off a 3.0RS body shell. martin smith here worked on that car when he was at the porsche design studio back in the day when they prep the car for the show circuits. the psychedlic "turbo" graphics flanking the car was done by him. if i bump into him i will ask who did wooden mock up turbo intake tracks. people on this forum believe that car was a runner. 959 frankfurt concept and boxster concept were also non-runners...

 

The engine number in GLP 870N / 0012 is 675 0022 so is the second production engine as 0-20 is not used. Don't know if this information lends anything to the prototype/pre-production/production model argument.

 

Very interesting…do you know why 0-20 were not used?

The 950/50 engine is unusual in that it crossed two Turbo production years - 1975 and 1976. From Peter Long’s: “Porsche 911, the Definitive History, 1971 to 1977”, the 930/50 engine has a serial number range of 6750001-6750297 (1975 model year) and 6760001-6760157 (1976 model year). Starting in November 1975, RoW 1976 930 Turbos were fitted with 930/52 engines with a serial number range of 6760301-676806.

My 1975 edition of the “930-turbo” workshop manual has a nice photo of a 930/50 engine. The workshop manual also includes specifications for the 930/50 and 930/52 engines and the only discernible difference is that the RoW 1976 Turbo 930/52 engine also included an air pump in the exhaust. In addition to an air pump, the 1976 U.S. 930/51 also included 2 thermal reactors and bypass valve. A possible explanation for the 930/50 engine crossing into the 1976 model year was that Porsche may have only homologated the 930/50 engine for the required 400 Group 4 production number since the addition of the air pump in the 930/52 engine is not reflected in FIA Homologation Nr. 645.

Like the chassis numbers 1-10 engine numbers 1-20 seem to have been 'reserved' for prototypes or such. The only actual example I know of though is a 3 litre 'versuchsmotor' # 666 0010 which was installed in a Carrera 2.7 chassis and used by Dr Fuhrmann. I was hoping when I saw Turbo #1 recently to read the engine number of that but unfortunately the original engine is not fitted at present. I do know the engine number is 694 XXXX but would have been interesting to see if XXXX was 0001 to 0020 or not.

 

i got my COA in the mail today listed interior as russet code 72 i thought for sure my interior was lobster as its an orange red color any input?? thanks

 

For 1976, Code 72 is listed as “Red Plaid (McLaughlan)” for the seat inlay in the 1976 911S, 912E & Turbo Carrera Colors and Interior selection book. Not sure about 1977 but your standard interior may have been Copper Red (Code 76) with Code 72 for the seat inlay – a fantastic leather interior fitment for a silver turbo (same as U.S. ’76 Turbo Carrera #0011).

If Porsche started engine numbers at 21 then the 950/50 engine count would be: 1975 - 6750021-6750297 (277 engines) and 1976 - 6760021-6760157 (137 engines): 277 + 137 = 414 engines fitted by the end of October 1975 - +10 margin for the 400 homologation number in Nr. 645 for Group 4.

 

For red 1977 leather interiors, the Porsche 911 Red Book list “light red” and “lobster” so “copper red” was a 1975 and 1976 red color. However, McLaughlan seat inserts (Code 72) continued for the 1977 model year.

Your COA probably only included the seat insert code and not the standard leather code. I have original leather samples of copper red, light red and lobster and they are all very different colors when you see them in person (light red and lobster are a closer pair match than copper red).

 

Copper Red and Russet are actually the same colour, Russet being used as the english language name and Copper Red a translation of Kupferrot which was used in the german language. Interior code 72 from the 1976 Special Colours brochure is Russet leather with Red Tartan seat centres and Russet velours pile carpet, the same as depicted in Idart's photo above. Lobster replaced Russet for 1977 model year when code 72 became Lobster leather with red tartan seat centres and lobster carpet.

 

For 1975 model year that would then make 277 engines for 274 chassis !

1976 gets a bit complicated with 950/52 engines and 934s in the same chassis range as the Turbos but with their own 930/71 engine.

 

If your car is a 1977 model year it would be lobster. COAs have a reputation for inaccuracy and using an interior or M option code for the wrong year is one of the main mistakes.

 

I have just recieved a copy of 'autocar' magazine from september 1975. It has the review of
'2 Goo'. Has it been added to this thread already, or should I photograph it for you all?

 

It has been added here - http://www.ferrarichat.com/forum/142469136-post1431.html

 

In 1977, both light red and lobster were available for the Turbo and both were a different shade than Copper Red (Russett) that was available in 1975 and 1976. People often confuse Can Can Red that is a very different shade of red that was not available until 1982 when it replaced light red for the 911.

I have a Porsche Audi 1976 dealer interior book and in the photo below, you can see the difference between light red placed next to copper red (I can’t locate my lobster sample). The 1976 dealer books are very cool as they have a semi-transparent 911 (and Targa) you place over the color of your choice and presto chango - the 911 color of your choice.

My '77 has a light red interior, and I would call it an orange red, although it certainly falls more towards the red side of the spectrum than the orange (fortunately).

 

Spotted this gem tonight.

Nice car, but looks like it is a 3.3 liter car, not a 3.0.

 

FIA Nr. 3076 for the Porsche Turbo (Group 3) included a photo of the 15 inch Fuchs and front seats. The listed weight for the 7” fronts - 13.44 lbs and “8 inch rears - 13.66 lbs. The homologated front seat (s) weight is just 10.35 lbs, complete with supports and rails.
