You need to know exactly what you need for turbo? hmmm.... well.... the list is pretty long. This is not going to be premade like the DSMers....

Turbo, manifold, downpipe, intercooler, intercooler piping, oil feed, drain tubes / lines, o2 housing, wastegate, BOV and piping, boost controller, EGT gauge, boost gauge, air / fuel gauge, SAFC, bigger injectors, new fuel pump, probably new slimfans because of clearance issues.... cant think of anythign else right now (1:15am) ... if I do I will post...

Dont let that list deter you. Most of the turbo kits you see cost upwards of 3Gs (I saw one for a 3G eclipse right at 4Gs).... if you get the parts used, and you dont want flashy instead of functional (like the TUrbo XS RFL BOV, just get a nice 1G BOV - cheaper and functional), then you can have a kit, labor included for about 2000 - 2500, depending on who custom makes your manifold and what turbo you use.
