2005 2.7 Question

[Giller]

I think it also depends when in 05 it was manufactured. I've heard tell that the early 05's are identical as Porsche wanted to use up parts. Later 05's switched to the bigger bearing. 06 is big bearing, 09 no bearing.

2005 was a transition yr from the replaceable IMS to the non-replaceable one. Chances are if the car was assembled in 2004, it has the replaceable IMS. Anything built from Jan 2005 to probably May could be either. Porsche didn't keep records so there's no way to know unless you drop the trans. The replaceable IMS fails at an 8-10% rate while the non-replaceable IMS fails at a 1% rate. By non-replaceable, I mean the one that requires the engine to be torn completely apart to be replaced (or drilled out) - essentially it's not replaceable without a lot of work.
