400hp how to get there?

Hi i have a sti type r version 6 have standard mods hks induction kit,standard vf28 turbo,full hks exhaust system,methanol injection kit(NOT BEING USED AT THE MOMENT)
Just wondering what mods would i need to reach the 400hp mark safely,i need around another 100hp to get there

garret gt spec turbo or similar:1500
740cc injectors:400
a clutch that will take that power,500
simtek or similar ecu that can run mafless as the maf in v5/6 are not up to that kind of power:1500

your also getting very close to the limites of the gearbox so two options dog box about 4000 or 6 speed from a newage car around 4000 k

also your engine wont last long either so alot to think about?

with all that power dont forget the brakes:1500

there probably lots of other things to but you looking 10 grand and upwards

400 is real depressing number, cost wise... the gearbox might stick it if it is fresh and your not launching it mad etc etc
Just so happens i have a turbo for sale that would probably see you 400 with the meth and lag wouldnt be bad
Your sti6 intercooler will need changing.. i recomend an sti8 tmic to keep lag down, sti8tmic are excellant and your meth spray will sort out any heat soak fears that a tmic present.

you could probably get to 360 for 1/4 of the price

as above 400bhp is not couple k as some people think...
