so i hav a jrsc on my 98 gsr running 8 psi. But i was wondering how to change out the crank pulley and the supercharger nos pulley before i get tuned, so i don't have to pay a shop to do it. Anybody know how to change them

 

?? Why would they be changing it, are you not tuning your current set up? And if your trying to swap them for a higher boost level, just undo the nut from nose pulley and crank? I really am not trying to sound like an ***, im just not sure what your really asking
