Boosting and NA-T does not fall near into the easy/least expensive category, so I don't know why some people are saying to do that.

Well OP your only options are ecu intake headers and exhaust. And those arent cheap. Dont cheap out, you're driving a Lexus not a Honda.

nitrous is the CHEAPEST AND EASIEST way to make any "real" power. period. about $500 and a 100 shot or about $2000 for srt+exhaust+headers+tune, you do the math.
and everyone is right, this is NOT a honda, although it has now become the new accord.
also search, you will find everything you ever wanted to know about our cars
