i wonder if i can add some horse power to my grand prix 06 3.8 base trim. by installing a supercharger from a grand prix gt, and if is possible what else would i need to change ? like an extra pulley, might be the fuel pump, and??? thanks 4 the help!!
the engine on the base model is III series i think its the same on the gt.
