The intercooler looks just like the one on my turbo 3.6 which should be the same for any 965. I can measure and post back. What is very interesting is that there are some changes in the CIS plumbing, detailed pictures of this would be of great value.
Looking in more detail, there is no tapping on the WUR, but still a RRFPR between the WUR and FD plus disconnecting the boost signal to the WUR make a lot of sense, means they take away the WURs responsibility to add fuel with relation to boost and give it to the RRFPR. At least on my car and the manuals, I have not seen this regulator, and like I said, makes all the sense in the world since the WUR is not very good at controlling fuel on boost.
