Bugeye / Blobeye STI's will remap to around 340bhp via Ecutek. I'll give you names of some good remappers if you're seriously interested!
Hawkeye STI with 2.5 lump (EJ25) has more torque but is known to not be as good in modded form (weaker) compared to older 2.0 block (EJ20). Can still do 340bhp on remap I think.
Alternatively you can try and find a JDM Spec C jobbie...now they're really good! Or a Litchfield T20/T25 if you can find one and you have the budger.
If going Evo...I'd plomp for a E9 260 version. detuned FQ300 really, cheaper, and can still be remapped to 350+bhp.
BUT....be aware that they're like tin cars, and luxury is not in its sales brochure.
Oh and you'll be visiting your local Shell garage WAY MORE OFTEN!
