Just need to address the IMS bearing with the better bearing and or the direct oil set up. I also have a 07 Cayman S with the 3.4 M97 engine, (improved IMS) and I am picking up an 83 911SC from a friend. I have owned Z's for years but my TT just doesn't cut it in the hills compared to the Porsches. The TT's place is on the Highway.
