I don't think that 1ZZ would offer any other benefit except that your accelerator would more sensitive to input. Remember it is just a valve that lets air into the engine. When I dyno tested mine on a 1.5, while it did make some gains at the top end and some slight improvement on the way up, at low rpms there was no difference except that because it was larger it let more air in quicker. So the throttle is more responsive. That's the main improvement.

Can you post a pic of your intake? Also is your throttle body electronically actuated, or is it cable operated? We might be able to determine if it would work.
