"Reverse" 2.4S COA From PCNA?

Jandrews · 09-09-2012, 06:49 AM

I have a '73 2.4S motor (converted to 2.7 RS Specs with MFI) that I would like to know which chassis it belongs to. My motor is 911/53 *6332186*. I started a thread on Early S Registry several years ago, and a gentleman there suggested I contact PCNA for a possible "Reverse" certificate of authenticity.

Does anyone here have access to such information? It seems to me that someone here in the vastness of Pelican would have a reference that showed matching motor and VIN numbers.

I am thinking about selling (or parting) my car, and would love to find either an S chassis, or THE S chassis that my motor originally came with. With all the information available online, and all the enthusiast forums, I would think it would be relatively easy to determine the status of the correct chassis.

Any thoughts on how to proceed?

Thanks,

JA

between chassis 1268 and 1304 by the registry listing of motors and chassis.

Hi JA,

Unfortunately this is not public info (except for the '73 Carreras). You can try to get PCNA to give you the match, but I'm pretty sure they will deny you request. Here is a link.

Thanks guys. So if I understand RSTarga, he is saying that it is one of 36 cars, i.e. between 1238 and 1304.

And thanks Fryardds. I am surprised that the enterprising types that collect early S information have not been able to "manually" produce such a database, simply from "known" matches. I would have expected there to be an outline that someone kept records for that would simply have missing spaces where there was no information. Then, as someone like me comes along with one of the puzzle pieces, you simply fill it in and eventually the outline becomes pretty full. Hmmm...might be worth starting such a document.

And why wouldn't Porsche make this public? And more frustrating, is why they wouldn't provide a reverse view? Is there some risk of fraud here that I am not seeing?

Hmmm...2012, and we still don't have match information for a few thousand cars from 40 years ago. Amazing with today's information access.

Thanks for the information.

The Early S Registry has a data base of cars with their engines but it is not comprehensive yet. There is a better record being kept of the SWB 911s. There is a 'lost and found' thread on the S Reg forum that would be a good place to put your engine serial number.

Thanks fryardds. I just posted in the Lost and Found thread.

But why wont Porsche release this info and open up the old Kardex vaults? The RS engine numer/VIN info is available, and I can´t really see a reason for them to be so secretive. Any suggestions or rumours?

Privacy + lawyers.

I don't think the problem is today's technology, I think the problem was 1960s and 70s record keeping.

I've been doing this for years, however the data is very hard to collect so I have only a few % of the cars in the database.
911/53 *6332186* is a 1973 engine, so late in 1973. This is 2186 out of 2231
targa 9113310908 has 6332187
It would be interesting to know the "xR" numbers on the case halves 901.101.101.xR & 901.101.102.xR (left & right)

djpateman...that is some good information.

I guess it would be overly simplistic and not realistic then to expect the chassis that belongs to my car to be one increment higher than the Targa you mentioned below? I.e. could my chassis number be 9113310909?

Also, my engine case is a "7R" magnesium.

Thanks!!

That would be unrealistic. The engine could have been in a coupe or a targa. Seeing as how the engine is in the last 50, the VIN is most likely in a 91133014xx Coupe or 91133109xx Targa.

Thanks on the 7R (you did check both sides to be sure? some people don't)
If you find the parting # on the top of the case, please let me know.

I can´t see any legal problems here. And the info is there. All the Kardex cards and all. So the reluctance to pass this info on remains a bit of a mystery.
