i'm in the process of trying to get 380 to 400 rwh/p out of my 33s2 so far this is what i've got,
-t3/t4 hybrid turbo hyflowed(rated at 450h/p)
-link ecu
-3' exhaust (turbo back) (race spec)
-e-boost 1
-Greddy plenum
-q45 throttle body
-nismo 720 cc injecters
-walbro fuel pump
-256 pon cams (8.5m/m lift)
-custom side mount turbo manifold
-sard fuel pressure reg
-hks adjustable cam gear
and a few other odds and ends but from what i've found out so far is that the most boost you should run safely day to day is around 18 psi thats about what i plan to run and see what i get but what i'm saying is that there is an endless list of parts and mods that you can do to your ride but be happy with what you get you will only get out as much as you put in and on a stock bottom end it's better to be safe than sorry so don't set yourself goals on a budget..........
