Heres a list off the top of my head.
-A pair of shorty headers, unequal length (BBK, MAC, JBA ect.,ect,)
-a pair of T3 exhaust flanges (if your using T3's)
-2 T3 turbos (preferabilly .60/.63's)
-I used -3an line for the oil feed, you can use brake line if you want
-2 bungs to either weld or drill & tap into your oil pan (1/2")
-Some hydrolic hose for oil drain's, make sure you run them vertical, without any bends.
-I don't run an Intercooler or a BOV, so you really don't NEED one, but if you can afford them they are nice!
-Boost gage, Boost sensitive FPR (Kirban)
-Misc. piping, hose clamps, scilicone sleves
I can send you some pics of my set-up if you want, hope this helps...
Two turbos and a carb...
