hi guys i need some help on tunning my car its a my00 2000 turbo only mods so far are blitz nurspec exhaust turbo back and baileys dump valve but my goal is to reach 330 bhp /about 330 torque and any ideas on what turbo i should use any help will be greatly appreciated

 

There's loads of choices for the turbo. A VF35 from an STi7/8 would handle that easlily, as would a TD05 16g from an early STi.
To get to 330 bhp though you at least need:

Full de cat ( both cats )
Ported headers and up pipe
Decent panel filter, not an induction kit!
440 Injectors
Wahlbro fuel pump, or similar
Fuel pressure regulator
Uprated TMIC STi8 version if you can get one!
VF28, or VF35, or TD05 16g Turbo
And then obviously you'll need to remap your ecu with a TEK3

There is probably more you'll need to do but that is a rough list
