from what I gather on this forum in my own opinions.
-Fuel pump(Walbro, Bosch)
-surge tanks & External fuel pump(may not be high on the list unless you drift or likes taking corners rather quick most of the time)
-Decent size FMIC and piping ( Hybrid, Trust, Blitz, ARC etc. depends on ur budget)
-Thicker alloy rad (Koyorad, PWR, Chinese spec etc. depends on ur budget)
-Good quality rad hoses
-lower rating thermostat (nismo)
-Upgrade panel filter ( K&N, BMC etc.) or, upgrade intake pipe and a pod in an enclosed box
-upgrade turbo ( GT2871, GT3071, TD06-l20g etc) rear housing depends on ur pref of response or top end. get a set of braided turbo lines aswell I.E oil, water.
-decent size Wastegate of a good brand if you choose external type turbo
-upgrade BOV (Plumb-back, vent atmosphere)
-Full turboback system with highflowed Cat ( X-force, JapBrand, Custom)
-Steam-pipe Exhaust manifold ( might not be necessary depends on ur turbo choice)
-Boost Controller( MBC, EBC. depends on budget)
-Set of gauges I.E Boost, oil pres, water temp.
-with Z32 afm ( Nistune, Power FC etc)
-Without Z32 afm, map sensor instead ( Motec, Haltech, Vipec, Power FC D-jetro etc. Depends on the tuner around ur area & budget)
-A set of Good quality plugs with proper gaps
-Camshaft( poncams, Easy cams, BC, etc.) A set of rocker arms stopper is a good idea too.
depends on the cond of the motor but stock internals should handle ur power goal. otherwise go full rebuilt with forged internals or stroked it if you got the cash.
-Upgrade sump ( tomei, Greddy, Custom etc.)
-Good Quality oils and regular oil change.
I understand that other ppl might have diff opinions on setup so, if i miss anything or add unnecessary stuff on the list then, feel free to change them. that way, i could learn new things too.
