77 or 78 confused or what!!!!

[Bazzer]

Hi Guy's, once again a little help is required[]
I am in the middle of servicing my 1977 911sc which was produced in December that year, on purchasing the car I was told that it was one of the first sc models and that it is actualy 78 spec[8|]
Is this true or should I be useing data sheets for the 77 model, the reason I ask is I noticed the plug gap size is different along with a couple of other items, any help would be much appreciated as the forcast is looking good for the weekend and I feel a spin coming on

Cheers Baz.

If it was built in December 1977 it's a 1978 Model Year car - factory switches model year in August.

Good point how do you find the build date out mine is a 77 2.7?

TryMarc Noak, email him car details and i think he should be able to tell you, he will have all your car details, chassis No, Engine No, Gearbox No, and the options your car had when it was delivered. Mines an 87 super sport but was delivered in 86.

Hi Baz,

Mark won't reply to you anymore as all enquiries need to go through Porsche Cars GB for a fee of £65 or thereabouts.

Now, As John already mentioned, Porsche cars AG looks upon it like this:

Your SC is a 180 bhp 1978 first series, and the model year 1978 was produced from September 1977 until July 1978. August is the annual closure of the factory whereby they then started to produce the next model year, i.e. 1979 from september 1978 onwards.

The carrera 3.o came just before your car and there are some differences. Therefore, do a check on the VIN or publish it here with substituting the last two figures with XX for security reasons and we can feed you back using the litterature.
Similar with your engine: there should be a number at the right hand side of the fan base publish the numbers with substituting the last two digits and we can tell you whether it is a 1978 MY engine or a later replacement 3 litre.

All the best,


Bert

The spark plug gap for all non-turbo 3.0 of that era is 0.8mm.

You should be able to tell the model year by a letter in the VIN.

My '84 model year carrera is an "E" if I remember correctly.

My '81 model year turbo should be a "B"

You might want to get a copy of the little red book for your era of car.

Hi, I have recently bought a Porsche 911 (1982). It's turbo-bodied with the RSR kit. I know it was imported by the previous owner 30 years ago and converted it to right-hand drive. (he had it for 26 years) before I bought it. I want to find out a bit more history of the car prior to it coming to this country. Can I do that by using the Vin and engine numbers and where would I post them ?

 

[John_Ward]

Your initial point of contact should be the Porsche distributor for the country the car was initially delivered to.... if you know!
