Mate do a search. There are countless topic on this. To put it short. You will need... Capa flash tuner, new high flow fuel injectors, high flow CAT, valve springs, fuel pump, exhaust and if the budget will stretch a new intercooler. These kinda mods should see around 300rwkw. Dont forget if you buy a manual get the 6 speed and budget for a clutch. If you get an auto budget for a gearbox re build (4 speed auto) If you get the six speed auto they are pretty strong. Seen a stock on with over 400rwkw and no dramas
