How is that crow tasting?
I was curious as well, seems the OP cleared it up, thanks though for the reply

You can look at the engine serial number to get an idea if it has the new big bearing. There is a thread here somewhere that discusses when the changeover happened by engine SN, in 05 apparently.
Mine was reman in 05 and is in the transition SN so I will have to pull the trans to see. Plan to do that at some point.

However, I'm not sure installing a larger or more robust bearing is a drop in with the factory stock 2000 to 2003 cases. There is also the question about the cam chain drive whether it is a single or double row chain and what role this plays in which bearing can be used.
I have read a couple of threads from owners on forums, including Rennlist, that indicate that they too have the larger bearing in their rebuilt or remanufactured engines.
The mechanic at my dealer explained that when they order parts, they have to accept the latest part number in the PET system. In the case of my engine, the part number was something like the third or fourth variation of the bearing (such as 996.xxx.xxx.04).
As pointed out, the only way to know for sure is to look at the back side of the engine. My guess is that the chances are high that a remanufactured engine installed in 2011 has the newer bearing

I feel like I got off easy. Mine was only $9.2K years ago.

Apparently the new Porsche bearing is readily installable in a 2001 engine as this is what the Porsche dealer put into mine when they rebuilt it in 2011.

Porsche will not sell a IMSB only a IMS.

There are 3 types of bearings for 996's, double row, small single row and large single row. Double row was the original, typical for 99's. Small single rows followed and they have been the least reliable by far. In around 05 the large single rows began. The large single rows require engine disassembly to replace. There is no hard cutoff by VIN for any of the transitions. Not that you get a choice, but if you did you would want the double row. Good service record and replaceable with the transmission out.
