Putting my Way Back Hat on and going back to 2012...

Porsche would not have provided any help or good will for an IMS failure in 2012 on a 2004. Tough luck sucka. And they wouldn't have any 2004 engines sitting in inventory to slap in, so they'd use the best possible fit available (possibly a left over 2.7). A 2.7 would not be plug and play as there'd be DME issues to address, but doable. Would have been an expensive repair.

So it's very possible to have a larger IMS 2.7 987 in this 2004. Have no idea about what stamped number the engine would have.

Is all of this a bad thing? Not really. You just need to know what you've got when it comes time to buy parts for it. The IMS will be a Gen III version and while not serviceable, it had a 1% chc of failure. As long as the oil chg intervals were good (5-8K mi or annually), that bearing will last.
