just to name a few parts....
turbo, manifold, piping, hose connectors, downpipe, oil feed line, oil return line, wastegate, boost guage, a/f guage, need to get the piping custom fit/bended to your car, intercooler, fuel management device (hondata, blue box plus wiring diagram for obd2 cars, (v)afc hack, fmu to name a few) wire to extend your o2 sensor, unless your downpipe has a bung in it....
where are you getting the oil from? oil pan? head?
dont forget the bov, if you get the hks ssq you will need to purchase the flange seperately for an additional 40.00, need to weld the bov onto the charge pipe, small hoses and a few plastic "T"'s, tap your oil pan in the right place, need some sort of flange to connect oil return line to oil pan...
now onto the supplies, shit load of tools, car jack, car stands, electrical tape, wire cutters, i forget the rest....
its alot of work...
preperation and the actual install.
