I am considering to buy a 1983 911 sc, gorgeously restored. It has a 4 speed manual transmission. I am confused because every way I search I find that it should have a 5 speed transmission. The current owner says it always has had a 4 speed. Any comments?

It could have a 901 or 930 gearbox. That is the only way I can think of an SC having a 4 speed. Could also have the incorrect shift knob... If reverse is all the way to the right and down, chances are it was a fifth gear. If it is to the left and up, it could be a 901 4 speed or 930 4 speed.

My 1973.5 has a 915 4-speed. It's original. Very few of these exist. Most people have never seen one.

I'm not sure if it was standard in 1983 though.

I have a 4-speed type 911 gearbox in my '74, originally out of a '71

Long and the short of it is that the 911SC never shipped from the factory with a 4 speed transmission.

The 930 Turbo of that era did have a 4 speed transmission.

The 915 4spd gearbox was still standard issue for the middies, 74-77. Type numbers are as follows:

915/16 1974&75&76 Carrera
915/45 1975 US& ROW 911S
915/48 1975 ROW 911
915/49 1976 ROW 911
915/65 1977 ROW 911

The 4spd was dropped with the release of the 911SC, and even the Sportomatic was only made in until 1979. Later SC production did not have a sporto option.

Hmmm... My '77 has always been a 5 speed. I don't think it was an upgrade when the first owner bought it new. :confused:

Note the dates with my type numbers. US discontinued the 4spd before ROW. Only the first couple years of the middies was a 4spd standard stateside.

5spd was always an option. A factory option. Tick a box when the car is ordered and it comes with a 5spd. I think it was about $100 back then.

Most US dealers ordered 5spd cars for their inventory. That was true all the way back to the longnoses. 4spd 901 was standard for quite a few years as well. Very often when one encounters an original 4spd car it was a Euro import because so few were ordered that way over here.

Do you have two neutrals?

Not sure who this directed to, but I can't even envision 2 neutrals, mine is standard 915 5 sp.

Maybe it's a Turbo (RoW/CDN)...

Sorry, i should have quoted the OP.

My thought was that car possibly has a 5 speed with no fifth gear in the transmission (another neutral)

Can you look for the tran type? On earlier cars it was on the bottom of the transmission, on the center web. If I am reading the 'Red book' correctly, the types are 915/62 ROW (Rest of World), 915/63 US, Canada, Japan, or 930/34 for all turbos.

Just to cover all bases, what is the engine type, this would be to the right and forward of the fan on a flat horizontal surface. Engine serial number would be on the vertical web to the right of the fan. Again, this is where the earlier cars are marked, assuming the later cars were done the same.

You are reading right, 930/34 for RoW/CDN Turbo which were 4 speeds.

Engine # or VIN would confirm if he could possibly hit the jackpot without him or the seller knowing it...

Turbo tranny in an SC would be a big fat turd. The gearing is all wrong. You would know it if you had a 930 tranny in that car.

Sorry, OT, but when I saw the thread title (just before reading), I thought Pelican forums were announcing shutting down :D . Never saw a title this long in my life (no complaining).

There is one twice as long floating around.

Wow, is that a garage or a display case?

The Vin number is ::
WP0EA0915DS170508

How about WP0EA091CDS170508... The 9 digit should be a letter, either Z or C

That would be a 1983 911SC US with Engine serial 64Dxxxx Type 930/16

When I search for this vin number in Scouser's Porsche vin decoder I get a usa/Canadian car made in Germany 1983, 911 sc cabrio 2 dr 3.0liter 5 speed Bosch fuel injection. So the bin number is correct. It does not mention what type of transmision or color is the car. Any way to dig more deep??

The transmission would have been a 5 speed type 915/63.

The CoA would give you the option and colours but the PCA will only issue them to the owner of the car.

Yes, 915/63 5spd. Something isn't original.

Nah...must be a 5 speed out of adjustment so bad that you cant get 5th. What is the pattern (where is (R)?

The seller has no idea what he is selling and with all due respect you searched the VIN and it came back with it being 5 speed yet in your next sentence you saying it does not mention transmission. Does the seller own a Nissan Tiida? If not that is what he should think about buying given his knowledge or arrogance.

The car is non-genuine.

You should walk away from this as you do not have the knowledge yet to avoid being ripped off. Just keep looking and reading till you understand more about the model of 911 you want to buy.

If you still interested then get it checked out by a Porsche Mechanic.
