I think the Scion/Toyota/Subaru BRZ will have the same power, with possible power adder options (like trd exhaust or intakes), while the STI will have a turbo. If they don't turbo it, it would be lucky to have 20-30 more hp (or 17-25 whp). Getting more than 30 hp out of an NA engine would require drastic moves like ITB's, cams, etc. I doubt toyota/subaru would go this route considering STI's have always had a turbo. Would it be cool to have a 240 hp, ITB'd, 8000 rpm screamer BRZ STI? Yes, but a 230 hp turbo would be better.
If the BRZ STI is just a weight dropping regimine, brakes, seats and suspension, I'll cry and then laugh at how dumb Subaru/Toyota is. Then push the old mr2 turbo over 400 whp.
