To my knowledge, ALL 911 and Boxster motors have and continue to have RMS issues. It is apparently a design issue in the both engines, which share the same basic architecture.
To my knowledge, the Cayman engine is an updated version of the old 911 3.4 engine that was in the 986/911 through 2001 I believe.
As such, I see it as no more or less likely to have an RMS issue.
I also don't see that engine as either more or less "robust", albiet it IS more powerful than the Box engines.
