this is a rough sketch of what you need..

Turbo Manifold- if you're getting a t3 turbo, get a t3 manifold, of course. stay away from obx and ssautochrome, theyre bad news. for that price you can get a cast iron one such as inline pro used.

Wastegate- theres two options you have here. internal or external. external ones run for about 200-300 dollars, assuming you're only boostin 6-8psi. most junkyard turbos come with internal wastegates so i doubt you'll need this.

Turbocharger- look for any junkyard turbo with NO shaftplay whatsoever. I found mine off of a mercedes turbo diesel. $150. in-out shaftplay means the seals are broken, side to side means the bearing is going bad.

Downpipe- get this custom made. you can get flanges from www.cheapturbo.com

Intercooler Piping- once again, custom pipes. you can get pre-bent pipes from kteller.com, jegs.com, etc... just map out the route and figure out the pipes you need.

Intercooler- any side mount intercooler from a 1g eclipse/talon/laser will do. 30-40 bucks. if you got the extra cash, go with a johnny race car intercooler. thats a little under 200.

Blow Off Valve- once again, any blow off valve from a 1g talon/eclipse/laser will do. 40 bucks or so. www.dsmtrader.com

Vacuum Hose and 'T' Fittings- any autoparts store should carry this. nothing special.

Oil Supply and Return Hoses- im not sure about HAN, but at honda-tech theres vendors who sell complete oil kits for 90bucks thats feed, oil return. you may need flanges depending on if the turbo has them or not.

Boost Controller- DIY boost controllers . Its just a simple valve with nipples to connect to the wastegate/vacuum line.

Fuel and Engine Management- since u got a 7th gen, im not too sure of the option u have. so AEM EMS maybe? definately upgrade your fuel pump. you dont wanna blow up your motor since it went lean because your stock fuel pump couldnt compensate for the extra amount of air.
