well from what i can tell you turbo kits alone will cost in a range between 1500-4500 depending on who you go with and what stage you want to get. It also depends on how much boost you plan to go with and how much money you ur willing to spend. You'll need the whole turbo kit that comes with the piping,turbo,etc...Some mods you'll have to do will include upgrading you injectors, fuel rail, but again like i said it depends on what stage turbo u wanna get and how much boost you wanna run. Adding boost will include also include doing some internal work to the motor. Neways if u plan on goin turbo good luck and have fun.
