You'll never make a set of ITBs from components for less than a grand, and you'll hit $1500 before you're finished installing them.
Toda has never made a kit for nonvtec engines. You'd have to swap your head first, then install the Toda kit. Which will, I guarantee you, require more than just the $1000 kit.
Plan on $1500 to get some ITBs complete and under your hood. Then you need to think about engine management, which will run you another thousand dollars. Then tuning.
