As I said in the thread that dissapeared, I would be concentrating on mid range torque rather than a peak power number, go the 26/30 add ITB's and cams, compression around 11:1 and rev it as hard as the valve train/bottom end will allow, dont worry about the final peak power number on a dyno....it will mean sweet FA on track if you get dusted up down QRs main strait by a 1600cc corrolla because your car doesnt start making power untill 6000 rpm and is all over by 7500.
then spend the money on some MCAs and big bastard brakes and you will be faster with 150rwkws and an excellent handling/stopping car over a car that you have spent squillings on to get 200rwks and have shithouse brakes/suspension
Plus an RB making an easyish 150-170rwks will be a shit load more reliable than one spinning to 9000+ and making 200.
Im not sure how much circuit expirence you have but there is more to a circuit car than a dyno number.
