A big turbo will NOT necessarily make you more power unless you get it into its effcientcy range. PSI doesnt mean anything, its all about airflow numbers...example:

my old turbo - 20g: I would see full boost (30psi) at about 3750-3800 rpms. Max Airflow @ 4000 rpms at most.
new turbo - 60-1: I see full boost (24psi) at 4100-4200 rpms, but max airflow comes in @ 6000 rpms.
