hi @Quinn allways good to see more hatchs on here,as @stants said your best off doing looks and handling on a na as you wont get much more power from it,i have had too 2.0sports na loved both but would cost thousand to get more power from them,i would go with a performance filter a nice exhaust someone like cobras sport will sort you out and make it sound nice,i have tien lowering springs on my hatch,not expencive and lower it about 30mm with out it getting so stiff it shakes your teeth out,any strut brace advertised for a hatch wrx will fit your car.the hatch wrx-s and wrx and rx all have same bodykit on but not sure about a l,have a look at pictures or put a picture of yours on so can have a look to see if its fitted with the same,if it has same bumper trim then this splitter lip will fit straight on https://www.tarmacsportz.co.uk/exterior-parts/08-10-wrx-cs1-style-front-lip.html just need to tell them you want the wrx splitter and not the sti one.
