you'll notice lightweight flywheel improving acceleration in the lower gears (1st, 2nd) when the levering effect of the gears is most used. in higher gears there won't be much difference. there's a nice thread on nasioc that discusses it
key thing is that a light flywheel can cause an intermittent misfire CEL (most people think this is caused by the crank position sensor seeing 'weird' things because the flywheel changes speed faster than stock) can you live with the thought of intermittent CEL? what about annoying hill starts (even a parking garage exit will be a challenge)?
my thought on this.. it is very easy to heel toe with the stock flywheel. keep it stock, avoid the headaches and worrying and hassle
as for getting close to 300hp for as little money as possible. sorry bro but the way to get 300hp for as little money as possible is to get a STi in the first place.

i can't find the article on that site that talks specifically about the gearbox, but apparently the safe upper limit of the 5spd box for long term reliable is around 250tq and the design limit is 300tq
basically what i am getting at is that if you want 300hp from the motor you aren't going to be doing it for 'little money' you will have to throw down big $$$ to hit your goal to maintain reliability, especially if you plan to be a track user... if you plan to just do a few highway pulls to impress your friends i guess you could just mod the car, drive like a granny 99% of the time and cross your fingers it will last until you are ready to switch car
don't mean to discourage you.. just trying to put another side of the story for you to think about. i've heard of too many people who dump $$$ into mod.. dump more $$$ into fixing and upgrading stuff that broke.. and in the end they go.. "screw it i will just get a EVO/STi/335/S4/M3/whatever" IMHO.. don't bother to chase the power goal. learn how to drive it hard and you can hang with very fast cars on a technical road or tight track
