im wanting 200 bhp out of my turbo once running, but whats needed to get the magical 200bhp.

at the mo it got,

collins stage 1 chip
full stainless mongoose exhuast
k&n pannel filter in drill airbox
hybrid stage 2 t3 turbo
- 31
low comp bottom end
standard intercooler.

what would this produce and what boost would i need to get to 200BHP,

cheers
