I'd probly stickwith the stock turbos. Somthing like
Full exhaust, Pod filters, Boost controler, 500cc injecters, new fuel pump, either new ECU or just reset your current one. Then put in clutch, cams, 500 degree certefied brakes like the Bremos that are on the V-specs. That would be a good start, if you are running alot of boosts you may want to consider a few engine enternals, pistons and the like. I'd say the whole thing could be done for 15-17k NZD. I may be off on the price figure so don't shoot me if I am
