406 turbo 8v 2.0 conversion, plz answer as soon as possible

[scoop]

helloo, i have a 405 sri auto 2.0 xu10j2c, and by tommorow i should be going to buy the xu10j2te, and i am so worried that i wont like the performanve after the conversion, so my cash for tuning the xu10j2te is buying a sport exhaust, iradium spark plugs, high pressure dump valve, a piggyback smt-7 management, a bigger intercooler, and a decent induction kit.my car weighs around 1200 kg so that might be goos for the 0-100 acceleration. so can u tell me what is the max bhp to reach with the tunings i featured?? plz answer me as soon as possible,thnxxxx
