So ik the motor may not be exact but it's the same motor out of the veloster just n/a. can I add a centrifugal super charger with out too many up grades? Ik the tunning part will be a little time consuming but do I need different cams, injectors, a new head? What do I need to make a belt driven turbocharged 2014 hyundai accent

 

Any alteration like supercharging or a turbo will not do well with today's computer controlled cars. There are many controls that need to be added and I don't know if you want to get involved with that. Factory installed and built are one thing, add ons are a completely different animal.
