Default Turbo upgrade

Hi, iv got a 2003 impreza sti, iv had it remapped to 325bhp, i believe im running a VF35 turbo, what would a suitable turbo upgrade be to get me to around 380-390bhp?
What injectors would i be running as standard and would i need to upgrade these also?

thanks

Thanks for your input Jacko4130 but dont wish to go that far, only really wanna change turbo (and adjust the map) so get 360-390bhp.

Is there anywhere that has turbo info, ie turbo number and what power its rated for?

Why, someones already stated an upgrade turbo is £350-500 which is a bit different to £1170.

How much will your turbo be the pooch?

It unlikely you'll get 380+ from a vf48 on a 2.0, possibly on a 2.5. A TD05 20g is probably you best bet on a budget.
