That is what I was wondering. With the Japanese motors, within one company, the engines are reused and remodeled to the n-th degree. I do not have that same experience with European cars.

For example, I had an Accord V6, and when the Acura CL-S came out with 60 more HP, we would swap in the cams and heads to get about half that difference. And it was a pretty direct swap, since one engine was simply a modified verison of the other.
