ok, want the magical 200bhp at wheels figure, but roughly wot spec and boost levels r needed?

erst running mfi management

parts acquired for new engine so far:

stage 2 hybrid t3 turbo
-31 collins actuator
turbo systems ecu
piper 285t2 full cam kit fitted to standard cylinder head
radtec fmic
cosworth fuel pump
rebored block with standard rst compression mahle +.29 pistons
standard rods
reground crank
heavy duty bearing kit
grp A gasket kit
uprated oil pump
mongoose 2.5" system
pipercross induction kit

thats my existing spec for the new engine build, but would rather make changes now before assembly if im going to fall short of the figure i want

any ballpark figures wot power that spec could make, and what changes u would make??? any advice appreciated
