im after a little more power...
First i'll tell you the spec as it is now, and with me being new to Subaru i'd like a few opinions on what to do next? Please 
STI engine
Vf24 turbo
Front Mount
Apexi power FC
3inch turbo back exhaust
Currently running 300.6bhp-330lbs/ft
Ideally i want around 340ish? Is it just a case of installing a bigger turbo??
Ideas please, like i say im new(ish)
Thanks

Well your issues will start with the ammount of torque your car has, the more torque the greater the chance of your clutch and gearbox going (and you have the weakest gearbox out of the lot).
If you want more power then you will need bigger injectors (550/565), uprated fuel pump (a decent one, not some crappy thing), brakes (the 2 pots are useless) and a remap, that should see you around 320-330bhp on the vf24, and as you have an old car, I would suggest a health check at your local speciallist before doing any more, though what happened to the original engine? (plus is your car a wagon or saloon?)

Sorry i forgot to mension.. It also has a walbro fuel pump and 440's which ive heard the injectors are good for up to 350?
Clutch isnt a worry as there is a good one in there which i recently fitted. G'box is the only issue in my eyes but until it breaks i aint fixing it
Original engine was ran with a TD05 running 317bhp-320lbs/ft and high end of 4th the piston/valve met somehow, causing a semi circle crack in the top of the piston
