if you have the factory manifolds on there, id say you arent even at 180 hp.. prolly closer to 170-175.. get some headers and you'll notice gains from both them and the true gains you should see from the whole exhaust. I wouldnt do a bigger throttle body only because you cant really tune our cars. The larger thottle body will make the comp go nuts and you could actualy lose power. Personally, get headers, a mild cam if you're only doing the cam, or a good cam with p&p'ed heads and intake if ya really wanna wake the engine up.. all depends on how much ya wanna spend...
