Porsche Reman'd Engine with upgraded IMS?

Mike is correct. Any factory reman built after 2005 will most likely carry the oversized third design IMS bearing. It can easily be spotted by the 22MM center bolt as it was the only IMS to use it.

Thanks guys. It is a 22mm center bolt. Here's a pic:





And the engine # does include the AT mark.
