Just coincidentally I was browsing the Borg Warner website the other day, and while I found a technical paper on VTG (interesting but a bit over my head) there was nothing on my search for Porsche and 718. I did learn that the company known as Borg Warner includes the German company formerly known as KKK. That made sense.
