The short answer (and Caterham's offficial one) is "YES".
BUT...chances are they will miss something so, if you are short of time for your install, check the contents very carefully against the instructions before starting. The instructions are not exactly great either and miss off things like how to fit the replacement tensioner pulley.
New clutch relase arm is included but not sure that a new CRB is so order one of those as well. New engine mounts are included but not the rubbers so you might want to replace the rubbers as well. All the necessary hoses and pipes are included as are all the addional fixings (bolts, hose clips, etc.) but you will need to resuse some existing parts (most of the sump bolts, some hose clips).
