I appreciated Phil's comments but didn't want to respond until things were headed in the right direction(in other words, I made my intent a little more clear).
My weakest area of auto knowledge is electrics and turbos. I imagine to get more lower and higher end performance that Phil is suggesting would include a programmable brain, custom cams, air/fuel sensor, modern turbo and properly flowed intake, head, and exhaust? $$$$$ Is that where you are going, Phil?
Yep, most of that, not sure about the brain, but most importantly a full re design/rebuild of the induction system and larger intercooler and oil cooler. Keeping the air cool is essential. I'm looking into superchargers at the moment and 2 stage turbos. Lighter flywheel will help too and not break the bank.
Breaks go without saying as the stock aren't great by even family car standards
If you want a cheap ~280bhp you could do what Elanlover is suggesting and add nitrous oxide injectors into your air system which could give you about +40 hp for about $600 US.
