Greddy Turbo

Does anyone know if the greddy turbo kit comes with everything i would need for a turbo for my 97 lude... if not, what else would i need.

Also, does anyone know if i would need to mess with the radiator to fit the greddy turbo kit in? My mechanic said some turbos are a pain because you have to relocate the radiators and such forth. Any info would be very helpful, thanks in advance
