Maybe I'm ignorant (which is very possible since I've never personally rebuilt a Porsche engine) but why do you feel that an intermediate shaft is so necessary? At the risk of comparing apples and oranges, Subaru doesn't use an intermediate shaft (on their 4 cylinders, or their 6 cylinders) and IMO, they are better off for it. Why add another system to fail?. Reminds me of the Mitsubishi 4G63 motors with their balance shafts. "Enthusiasts" remove the shafts all together because they aren't necessary and its just one more system that can cause timing belt issues.
