2004 996 or 2006 997???

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.

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?
