911sc or 930 mystery

cgh911sc · 02:28 AM

Hi,

I have an '83 911 with everything 930... engine, transmission, brakes etc...
Also, the car is a slantnose, waletail, widebody, cabriolet car.

I sent off for a Porsche Certificate of Authenticity and Porsche returned the
Certificate stating it was an '83 911sc cabriolet and stating they had no records of the production Date of the car, nor records of special wishes options for 1983.

Therefore they had no records of the car being a special wishes car or not, nor reference to it being a 930 or not just 911sc cabriolet.

I thought the car was a 1983 911 (930) 3.3L turbo cabriolet.

Anyone know what the deal is... Does the lack of records for the 1983 cause the Certificate to default to the car being a 911sc?

What am I missing here.

I think the Exclusive department would have mentionned the modifications , especially for the slant-nose.

Post your serial # and someone here will tell you what you've got.

serial #

Is there a serial # or did you by chance mean VIN #

Thanks,

You would think so, but Porsche said the records are missing as
they can't find any special wishes info on the 1983 cars.

They also stated they could not find a production date for my VIN either.

Strange...

83 was years before they started making 930 cabs. I recall they were reinforced differently so it would not have been a slight modification.
Pete is right to ask for the serial # (not the VIN, you already know what that says). The engine and trans will tell you about their history. Would be interesting to know if they came from different years for example.

is there a serial# or VIN number that is stamped on the body itself. the vin on the dash can easily be changed.
i saw one of those car shows where the guy pulled a fender off and the VIN on the body did not match the vin on the dash. turns out it was stolen.

The 930 was produced from 1975-1989 with slantnose produced in 1983 although slantnose options were available for the us market after 1983.

This is what I have seen here and other references as well.

My engine# is: 6891286 (stamped on the engine: 930/83)

Not sure what the transmission serial number is but I was told it
is a 930 turbo transmission and it is a 4 speed which sounds correct. I will have to look and see what the serial number is.

6891286 is a MY79 US/Cdn, 3.3L, 930, model 930/64

In all likelyhood you have a car that was converted in a shop in the US, it was very common in those days.

The first regular production turbo cabs came in 1987 and would have a g50 5 speed, instead of the older 4 speeds

Porsche changed the engine serial # method in MY1982 to 2 numbers, letter, 4 numbers. Your SN might be a very late 79 motor as those motors started with 6890001.

Edit - Bill beat me to it.

The first 911 Cabriolet produced in 1983.

In 1981 a Cabriolet concept car was introduced at the Frankfurt Motor Show. Not only was the car a true convertible, but it also featured four-wheel drive, although this was dropped in the production version. The first 911 Cabriolet debuted in late 1982, as a 1983 model. This was Porsche's first cabriolet since the 356 of the mid-1960s.

The 930 remained available in Europe, and for 1983 a 330 PS (243 kW; 325 hp) performance option became available on a build-to-order basis from Porsche. With the add-on came a 4-pipe exhaust system and an additional oil-cooler requiring a remodelled front spoiler and units bearing the add-on often featured additional ventilation holes in the rear fenders and modified rockers.

The 930's didn't get a 5 speed until 1989.

yes, cabs were available for MY83, but turbo cabs did not become production line items until MY87

W/o documentation that it was a special wishes car produced at Weissach it would be hard to believe that is indeed a factory '83 turbo cab.

You of course can believe whatever you want.

Another odd thing, I can find no record of a US engine # for MY79 -85 turbo, there are 'MY78/79 and MY86-89, I vaguely remeber that there was a period of time when there were no US 930s, it must have been that era
For '83930 turbo
RoW is 930/66 serial # 67D xxxx
Cdn is 930/66 serial # 67D xxxx

My bad, I have to look all that up not being a turbo fan

In 1974 Porsche introduced the first production turbocharged 911. Although called simply Porsche 911 Turbo in Europe, it was marketed as Porsche 930 (930 being its internal type number) in North America.

cgh911sc · 02-12-2014, 06:21 AM

Look's like I have more info then Porsche on the 1983. They have lost their records for the year 1983 and have nothing on the special wishes production cars.

I can't even find anyone who has a 1983 Slantnose Cabriolet. It look like it was
built in 1982 and sold as the first slantnose Cabriolet in 1983.

Yeah, from 1980 through 1985, there were no US turbos.

I've never heard of a 930/83 engine. You sure it wasn't a 930/63? That would be a California spec '79.

Yes, my car is from Europe...ROW I guess...

Porsche would not have built a new Special Wished car in 1983 and put a 4 year old, used engine in it. As others have pointed out, you most likely have a regular cab that's been modified at some point, most likely not by the factory.
