Well u can gain a maybe 20-30hp with ur typical bolt ons: intake, header/downpipe, exhaust, tune. Or you can forget the wimpy stuff and go with a zzp turbo kit (my personal favorite) Just with the stage 2, I think, your car will rip!
Well you dont want o waist money, so look at what you eventually want to do. Lets say u want to turbo/sc ur car, dont go and spend $400+ on a header/downpipe when ur gonna need to replace em ya know?
do the easy stuff first. and stuff you will use in the future like intake, maybe catback or something.....do forget your general maintenance. if you just got it you might wanna change oil, plugs, wires i always do even if the previous owner said they just changed them. first step to making power is running good!

auto or manual????
if auto go stg2 turbo from zzp, if manual,, try to ask for stg1 (stg1 they took it out of the site)
get some 60lbs injectors and build an air/air cooling system.

You need to decide on spending goals and power goals.
In the long run a mild SC or turbo setup will be a much better power/price ratio as compared to a full intake and exhaust/tune setup.
