it just seems a better option becuase i havent hurd of anyone with a k03 hybrid rather than the k03s. ill see what the guys at cr turbos up the road say. its only in the pipeline really.
 
Benny runs a CR Turbos hybrid which are made from K03 base units, as do other members on here. If you take a K03S to CR Turbos you're only wasting money as they scrap the part that distinguishes a K03S from a K03 anyway. Note there's technically no such thing as a K03S, it's just a later variant of the K03
