The 993 Porsche motor suffered from the same design flaws as the WBX
motors, only Porsche realized they had a problem after just a few yrs of
selling these.  They quickly brought in the 996 motor that was properly
engineered for holding the water inside and to not need frequent expensive
rebuilds.  The 993s I raced with were unlikely to last one race weekend...
Most who brought them to the track brought along spare motors and a crew to
swap them quickly when they blew.
