Two people have recommended SC/ 964 cams. Please correct me if I'm wrong but the upgrade to either SC or 964 cams would only apply to a 930, not a 965 like spjuvern has.

My understanding is that the factory cam grind for a 965 is the same as the 930 as evidenced by the part numbers:

1991 Turbo
965 Left 930-105-143-03
965 Right 930-105-246-00 This cam contains the extension for the power steering hub

1989 Turbo
930 Left 930-105-143-03
930 Right 930-105-142-03

The SC does have different part numbers indicating a different profile:
1989 Carrera Left 930-105-147-10
1989 Carrera Right 930-105-148-10

It would be interesting to see a table with the lift/duration of these cams. So far, I have not found one.

Thanks,
Mark
