you will need a bigger turbo (hypergear hiflow/3071 or 3076R - may need custom manifold & ext gate depending on turbo choice), Z32 AFM, bigger injectors (440cc or bigger), tuneable ECU (nistune/PFC/Haltech etc) & FMIC.
speak to Trent @ status/chequered tuning, and he can sort all this out for you, drive in & drive out a happy customer
^ u do not need cam gears on a RB25 NEO however tomei pon cams are a good optional extra!
