Didn't henz get 300+ with only X3, injectors, hiflo cat and tune? Theres 2.5K.. but a BA would prob need Vsprings too.. plus on the safe side a walbro.. If I was you dude: X3 and tune $1500 Injectors ~$400 and ~$100 to fit Walbro ~$200 can fit it urself if you know how, but should be around $100 to fit Hiflo Cat depends on brand, size etc.. $500 fitted Valve springs ~$400 and ~$500 to fit Should get ya around the 300rwkw.. Next on the list, cooler/intake, waste gate port/ flapper/actuator, maybe rest of exhaust, surge tank... the list is endless.. What tranny have you got? Brakes, suspension...
