Either way you go you're looking at spending between $4k-$6k. Each option has its pros and cons. for the S/C the pros are cooler inlet air temps, less problems with convection heat and simple belt & pulley changes to alter the boost psi.and almost instant boost. Cons are parasitic loss of some of the HP from turning the blower and limited pressures (on under hood designs).
For the turbo pros are more mounting location options, no parasitic drag, usually smaller in design. Cons are high temps, changing boost pressure usually takes a larger turbo, turbo lag and more parts involved.
