this has been covered a fair amount already in previous posts, so you might have to hit the search button and do some digging, but here are my thoughts - however others may differ and to be honest probably will knowing this lot!!
The engine is basically the same as a standard STi so the tubular fanimould, exhaust, filter etc..will be good to see say 320-340ish?
The bottom end is good for approx 400 - and so is the top mount intercooler too. You will need new turbo, injectors, remap etc....
Anything above this 400-450 level, then you are talking a re-build with better more reliable components plus the above turbo and injectors...
There are a few running decent power on stock engines...but not what boost this is at, how may miles they have done, and ofcourse how many of these miles are full fat track miles.
Keep it drinking 98 with maybe a bit of meth thrown in and you will be OK for a few months...then the urge for more will kick in.
It doesn't matter how much you have...you will always want more. The trick is knowing when to draw the line and have a good drivers car rather than simply chasing numbers and ruin it.
