Robust from hp figures doesn't mean robust from harmonics. Harmonics are a huge deal for the miata engines. Only ATI came out with a stock harmonics balancer replacement for that engine series until someone else recently went to extremes of engineering a correct balanced AL piece.
I'm new to working on the boxster though. Is there any known issues with harmonics in previous iterations of subies?
