Theres not much hope for big bhp with a that engine at the current time but you could modify any of the following :
air filter/ forced air induction
cat back exhaust
cams
remap/chip
pulleys
manifold?
if you can get all that on the list and fitted you may see an increase of 25-30bhp, maybe! but it will cost a lot!!!
