Just speculating, but 98 octane fuel and a tune or E85 and a tune to get some more power from ignition advance?
Probably still increasing power by small percentages over a low base.
That aside, probably big-dollars spent on raising compression and/or rev limit and/or cams etc. to try to squeeze a bit more out of that low base.
Without big displacement or big revs you are starting behind the 8 ball with a small naturally aspirated engine and the heavy mass of an all-wheel-drive car (as opposed to a Mazda MX5 or something light).
I know what its like to really love the car you have and wanting to upgrade it to the max, but your best bet would be trading it in for a turbo model (or if you really like NA, a 3 Litre NA model, or ditch Subies and get something with an LS V8 engine or something).
If you're on P plates - it genuinely won't be long until you are off them and can upgrade to something with power very cheaply/easily.
