Overheated to 250, died on side of highway, left stranded

[Overdrive]

Realize too that there is the IMS bearing retrofit and the IMS upgrade, two different solutions, the latter being the more complete, and more expensive, solution to the IMS issue. The retrofit is simply a replacement of the IMS bearing with the more robust LN Engineering one. The upgrade is exactly what it says, an upgrade of the IMS bearing to a "triple-bearing" style one. That requires disassembly of the engine and sending them IMS out to have the work done by someone like Jake Raby. Obviously you're talking a lot more money there, but the engine's not in the car yet, so it makes more sense to have one of those things done then before the engine ever makes it into the car.

Also, just keep in mind, that's only one failure point addressed, and there are still several others that exist on these engines, so while it takes care of a big problem, there are still many other things to check and possibly address on a used engine (things like chain guides, water pump, cylinder sleeve slipping/cracking, air/oil separator, etc.). Since you're dealing with a Porsche specialist, I expect they'll know what to look for and spot any of these issues on any block they look for.
