The 965 engine, which is the carried-over 930 engine with small enhancements, would accept SC cams but the right hand cam would need the drive nose for the power steering sprocket.

The debate about which cam profile's superiority goes on without end on the board here and also on Rennlist. I find it interesting that the factory chose the 964 cam for the 1993 Turbo S lightweight that I mentioned earlier.

My opinion is that since the 7/1 static compression ratio makes for sluggish off-boost performance, I'd go the 964 route to make on-boost performance all the more fun. Having said that, my car pulls to the redline nicely with stock cams and turbo so how much better would 964 cams really be?
