I never did remove the oil cooler. My oil pressure didn't change; still at least 1 bar per 1krpm but not excessively high. I never did find out for sure what the cause of my initial high temp problems were, but they haven't reoccurred. I still wonder if I had some sludgy buildup in one or both of the oil coolers from the car sitting so long. The new thermostats did appear to help somewhat, although the old ones seemed to open OK in boiling water.
Good luck with your thermostat replacement. I found that I was able to get the housing caps off by soaking with PB Blaster once a day for a few consecutive days and then using a small pipe wrench as I recall.

Lastly, what do you attribute the success to, changing the engine mounted thermostat as well as the other that you already had been messing with? Working on why my front (wheel well mounted) t-stat isn't opening either and have ordered new internals from Porsche.
Thanks for any input and glad you were able to figure it out.
