true but 20v corollas did it. do some calculations, and using the right combination of runner length, velocity stack length, and plenum size, and it will perform similarly. I personally like the idea of having ITBs, but i dont fancy the fact that 99% of them just suck in hot air from the engine bay...minus the K series honda swaps that face forward out the hood vent or something. i would almost prefer to have a plenum setup with a large diameter intake pipe feeding it cold air. but then again, the MAFs still becomes a restriction...a 3" one at that. but i think on a regular KA it would be fine.
