I am reasonably clear on the last 8 characters of the engine serial number. I seek clarity on the first characters. "M96" or "M97" is obvious as is the "/" (which is sometimes reported as a "7" or a ".". It is the next few characters which appear to apply to engine displacement. I 'get' the '2x' series but wonder about the "0x" series. This is more than curiosity on my part as the years roll on, more Boxsters, especially gen 1, are getting different engines with their own special quirks.
