blower is the way to go.
stick intake exhaust plenum t/b and a tune and if your lucky u make 260whp witch is like 30 gain from bone stock.
u might c 20-30 to the wheels with just a cam. u cant relly put a good size cam in the 2v without fly cutting the pistons.
so its spend a couple grand buyin all the bolt ons / a nitrous kit and havin them installed or pick up a used pro charged kit for around 2500 bolt it on and make more power.
