1973 911 T-V Sporto RoW authenticity

[DanPez]

Hi all,
I'm fairly new to the forum an was wondering if someone here can authenticate my Sporto 911T.
The vehicle has been restored and replace with some unique body parts, metal rear flares, fiberglass spoiler, fiberglass duck tail and repainted Lapis Blue from its original Light Yellow .
(Did not come out of the factory this way!)





The 2.4 l motor has been rebuilt and the previous owner has painted it red ..... S style. (Mostly for looks)



The engine case was replaced with # 6120770 (72 F/I Pump 911/51 USA T-E case)



But I do have its original case.



The question I'm asking myself is if the tranny came out of the Porsche assembly with a 905/13 instead of a 905/21.
Reading up on one of the "Original Porsche 911" books it mentions that at this time the Sportomatic transmission was special order.



Could the worker have picked a unused 69 911T tranny from the shelf and installed it on the vehicle?

Thanks in advance.

"Could the worker have picked a unused 69 911T tranny from the shelf and installed it on the vehicle?"

If I understand your question, I don't think that's very likely, especially considering it would be 4 years old, and all the mods done to your car. I leave it to the experts, but generally, I've learned that the usual time variations occur is during year to year transitions.

Porsche can verify your car details through a certificate of authenticity. Good luck with your research, and welcome to the registry.

Hi Scott,

I was thinking of ordering a COA from Porsche ...... but census indicate that the information on these certificate is not detailed and are not that accurate. Besides this one is a RoW.
Would they have it?
The google images I searched on North America COA, for that era, have "Information Not Available" on a number of sections.
Tell you honestly if that's what Porsche will supply me with ..... It's not worth the money.

It would be great if calling or emailing Porsche they'd confirm "We have all the information concerning your vehicle sir!"
Then ... I'd go for it!

Tks

You can call them first and they will help with information. You do not have to buy the COA first.

The engine number is for a 73 T carbureted Sporto. PCNA will sometimes verbally confirm an engine/VIN match without your having to spend on a CoA.

I gave it a try .....
I sent an email to COA to see what they'll have to say about all the information being available.
Except for the 911 TE (USA/CDN) case that's on the vehicle now I know from the information on the 911_Katalog "V-Pages" that all s/n's come from 73 911 T-V SPM.
S/N of the tranny has reference to a 69 911 T Coupe SPM.

Does Porsche get their information from a Kardex?

[Eminence Gris]

The old Kardex system was retired in 1970, I believe. Info on your car would come from a newer record-keeping system using a couple sources.

The sportomatic transmission changed from a '905' type to a '925' type with the beginning of the 72 model year. Seems unlikely that in 73 they could be using up '905' type transmissions. Notice I said "unlikely"

[DanPez]

People that know these cars find it odd when they see a 1973 with Zenith carbs. (73 should be FI ! No?)
This baby is a RoW type and I would imagine one of the last carb motors manufactured.
This is why I'm asking myself if the workers just picked the leftovers parts from the shelf. :lol:

Please correct me if I wrong .... Ideally if I rely on the Porsche's V-pages parts document I can assume this:
The chassis # and the VIN plate indicates s/n 9113510319 ..... and the following would be what should have been installed:

911- Model 911
3- Year 1973
5- 911T/V
1- 911 Targa
0319- Serial number

911 TV Targa 73 (91135 10001 - on) has an Engine Type 911.57 / 911.67 (9113510319)
911 TV SPM with 911.67 engine has a case with s/n 653 9001 – on (6539062)
911 TV would have a 905.21 tranny with s/n 743 0001 – on (4-speed SPM) (Missing)

(edmayo)
What I've found ....
In 1972 and 1973 the 911 E / 911TE (USA) (CDN) / has a 925.00 tranny with s/n 762 0001 and 763 0001 – on (4-speed SPM)
In 1972 the 911 S has a 925.01 tranny with s/n 762 0401 – on (4-speed SPM)

COA was very quick and kind enough to tell me what information they have.
The MSRP and Production Completion Date was not recorded by Germany at the time therefore not available.
The other information (engine number, transmission number, interior / exterior colors and factory installed options) would all be supplied on the COA.
