for starters, your going to need more fuel: fuel delivery (fuel rails,fuel pump injectors, maybe some fuel lines,) your also going to need hot side piping and boost side piping, FMIC, a properly sized turbo, oil lines(for turbo), MAF sensor, welding supplies, AFR guage, wideband o2, a few bolts and matching nuts, a plan, someone to tune it. these are just a few of the things that i can think of
hell you might even need a clamp or two
and dont get too heavy in the boost or you are gonna need pistons, rods...
