Engine Types

[chris_seven]

I have been looking for a list of engine types against crankcase materials.

Does anyone know where I may find the information.

Thanks

It may be in the back of Fere's Porsche 911 Story, or in Bruce Anderson's Porsche 911 Performance Handbook. The main thing was that the early engines were sand cast Aluminum, with the 906 being Magnesium. 911R was Aluminum I believe. Then they switched to Magnesium for everything until the 3.0 RSR engine came along, after which the 911SC and onwards used Aluminum. 935 and 936 used Aluminum.

Max,

I will look in Paul Freres book but I haven't seen the list in Bruce Anderson's book.

I know for example that a 901/10 is aluminium and also a 901/02.

I think a 901/06 is as well but it would be good to have a definitive list.

Carerra 3 motors are certainly Aluminium as are SC and i can deal with all these types.

I guess in I knew that all O and A programme cars were Aluminium and that All B Programme were mag I could work it out. I have been told that some late A programme cars had mag cases but I am not 100% certain.

I will have a go this evening and try to come up with a provisional list.

Trying to correlate the casting numbers would also be good but I am sure someone has done this already

If anyone does, it would be "davep" on ESR. (Early 911S Registry).

There were also some dimensional copies of the mag 7R case done in aluminum.

The factory wanted light till it started breaking .
