Only 5 Factory Sportomatic cars ever build ? Options

[SirAndy]

Does that sound plausible ???

Urban Knutsson, owner of a '71 914/6 Sporto, writes a letter to the factory asking about the number of 914/6 Sportomatic cars produced ...

The reply from Porsche:

Dear Mr. Knutsson,

Thank you very much for your letter of October 10.
Referring to the latter and to our phone call of
October 9, we herewith inform you that of the type
914/6 Sportomatic we built a total of five cars for
experimental purposes.

Your car, which is a really rare one, was exported
to Sweden in February 1971.

In the hope of thus having been of some assistance
to you, we remain,

Sincerly,

Dr. Ing. h.c.F.Porsche

this may be a dumb question, but will a sportomatic tranny fit a 73 Ga case? Or must it be a 6

it's -technically- possible to do a /4 Sporto, and if you look in the Clymer/Lash book you'll see some photographs from the -one- (possibly two...) factory prototype cars.

The big problem is the oil pump for the torque convertor. In a /6 this is a separate auxilliary oil pump driven off the left camshaft. There's no room for another piggyback oil pump in a /4 in the standard location without getting in the way of the fan. (Yes, there's that factory car. I don't know how they did it. The photographs of the oil pump in question are made with the fan shroud conveniently gone...)

But cooling on a T-IV is a bit marginal, and the Sporto torque convertor uses engine oil, so you have the double-whammy of more heat from efficiency losses in the torque convertor and more heat from the engine working harder to get that back. So IMO you're definitely looking at some kind of additional oil cooler.

-anything- can be done with sufficient quantities of time, effort, and money, but this project has yet to rise to the 'Let's Do This' threshold for anyone, AFAIK. It'd be really hard, and for what?
