its a rough question.. it will come down to what i thought how much money do u have and are u a professional fab.. there both really fun. a sc is always there with power and u can make the same power as a turbo. a turbo will be cheaper if u can fab it all up yourself.. its been done for under 1000 on turbomustangs.com from a junkyard setup... now if u cant fab ur best bet is to go with a novi 2000 or a procharger with a hci u easily make enough power to split ur block in half and send ur tranny out the back.. so far even tho my plan changes once a week kid me not i think im going with a sc for now and bulding a new engine over the summer.. just rember one thing that kicked me in the balls u need a suspesion, drivetrain, and fuel system that can take what u want
sorry for the long response
ps. be ready to get a dart block
