What link is between these two companies?

-I've been told recently by a co-worker that Porsche basically designed for Fuji the heads on the 2000 and later Subaru 3.0 H6 engine. The variable valve timing system on the later Subaru H6 heads is basically just Porsche Vario-cam, which is used on their own H6 engines and was originally developed for the 968's inline four cylinder engine, which is really just a derivative of the 32 valve 928 V8 engine.

It occurs to me that a company such as Fuji could probably develop their own cylinder heads and variable valve timing system for less than it would cost to pay a prestigious company like Porsche to do the same thing. On the other hand, Porsche actually makes more money doing engineering work for other companies than they do from making their own bespoke cars.

And if they hired Porsche to design their heads...what else? The 3.2 liter H6 in the Porsche 986 [Boxster] has two auxiliary shafts, one above the crank and one below, in order to drive the camshafts. The heads are interchangeable, unlike the Subaru H6 which has a left side and right side head and no auxiliary shafts. Thus, the engine in a Subaru is not a Porsche motor, but one has to wonder how much input the folks in Stuttgart had.

N!
