I am struggling between purchasing a 2004 911 with the serviceable IMS bearing and a 2006 911 with the non-serviceable larger internal IMS bearing. What is the consensus on the reliability of the revised larger IMS bearings? A Porsche mechanic I spoke with says that the IMS bearings on the 2006 911 are reliable.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The 997 would be the more developed model and those bearings have had far fewer issues - but - there still has been some failures. There are kits available now that direct pressurized oil at the bearing for both the 996 and 997 (2006+). It is supposed to eliminate (greatly) the chance of bearing failure. I'd research those kits (sorry, can't remember who make them) and lean towards the 997.

Does anyone know what Kit this might be??
I think this is the kit: TRS IMS BEARING DIRECT OIL FEED KIT (DOF) - 05-08 997/987 Looks promising. Anyone install one of these?
