I rode in a gsr that had the 4 Hyabusi (SP?) itb setup on it and I swear it felt like boost when vtec engaged. I was very impressed. I did hear they are very difficult to tune though.
I've seen many good homemade itb projects, it makes me want to try one for sure. I have a set of itbs but I don't have the heart to cut up the intake(yet)
