turbo kit or saleen SC

Hi, i live in venezuela and i have many friends... they buy a procharger... and i wanna buy a supercharger.. but i think saleen its better... but i see many videos of dyno runs with a turbo kit and .. and now i dont know wich is better.. a turbo kit or a saleen SC...
I wanna a complete kit... i wanna the brendspeed kit 4 saleen SC.. but i wanna some information about this kit.... can i put this complete kit with the 3.0 pulley on my stock engine?..
Thanks

im gonna make more horsepower with the turbo?....

I get a mustang with a ford dealer... they imported the car.. if you come you gonna see 1 mustang every 5 minutes.. jajajaja...

And my dealer tell me if i wait to december.. they gonna sell the gt500...

Ps: today i ran with a lt1 with 4.10, CAI, powerchip, LT and borla exhaust... and he tell me that he likes the sequential tailights.... , tomorrow he gonna put a semi slick and we gonna run again...
