I would highly reccomend getting the supporting mods.

-GT25R
-Exhaust Manifold
-Software!!!!
-DV
-MBC or EBC
-VR6 MAF maybe
-Inlet hose from Neuspeed or APR
-FMIC(does not have to be on at the same time, but sooner or later you awnt to have one to fix the timing)
-Exhaust w/ DP
-TP or HFC (Not needed but HIGHLY reccomended)
-Clutch (You will need it sooner or later with this sort of set up)

Then a few others that you should have t help maintain

-New fuel filter
-New spark plugs
-New boost/vac hoses
-New 02 sensors
-Check the PCV system, it may need to be replaced
-Boost gauge
-2.8/S4 engine mounts

Dont think iam missing anything.

*edit* You will need the correct sized injectors and possibly a new FPR.
