IMO it would've been nice if Porsche had bumped the 993 C2S by 20 horsepower back then to compensate for the S model add'l weight and to distinguish further from C2...but with the final years of the 993 reaching 282 HP they had probably already pretty much maxxed out the practical HP to be extracted from the last iteration of the air-cooled 3.6L.

In Europe, some of the 993 Carrera models had a 3.8L motor with 300hp+ (from the 993RS) instead of the usual 3.6L. I'm not sure if the 3.8L powerkit was only available on the S or not. However, the 3.8L was never offered in the US...
