Looking to upgrade superchargers at rebuild to larger wheel and injectors. And possibly impellers. For a step by step do I need anything else or will this get me a little more. What size impellers do I start with. Thanks.. they are 215s
 
Xchargers with injectors will be about 15hp per motor with the injectors. You really should call or email PWC Muscle. I did drop all the info in the last post. For what its worth i just had both of mine rebuilt and they both needed impellors. For the $400 more for the chargers and the $500 in injectors i did NOT go this route. Wasnt worth it to me to deviate from stock. PWC sells the chargers new and injectors for $1200 each motor as a kit if you dont rebuild. $2400 was still to steep for the minimal HP to me. Anything beyond that the total cost with IC and RRFPR and TUNE is about $6000
 
More than likely, you will also have to install external intercoolers, all the routing of the hoses, etc.
