Anyone know what this would be called?, And if you do, can you tell me where to get it? Options

I need a valve that only opens when the throttle is fully engaged (hard acceleration) but stays closed then idling/cruising.

From where did that manifold come from?

on the intake manifold that I had posted pictures of I believe that the second set of runners are closed under engine vacuum and when there is no vacuum the second set of runners are allowed to fully open.
so basically when you are at idle(engine vacuum) the second set is closed and as you press the throttle the the second sets opens as it gets closer to "0" vacuum(WOT)

This is not quite open ONLY at wide open throttle but could possibly be ran to some sort of vacuum switch to control it.

And also this is a 7AFE manifold and head incase someone did not know.

It is for a 7AFE I believe it is a JDM 7AFE intake manifold and head, I don't remember exactly what kind of car it came off or if it was even a 6th gen celica, I have had it for a few years already and I can't remember anymore.

only odd thing about this head is that it does not have the hole for the distributor, I have not done research on them in a while but I could not find a 7AFE with an oem distributor-less ignition system.

I plan on probably losing the whole butterfly setup and just opening up and siamesing the intake and if I can, weld up and siamesing the intake as well so that way I can have more runner volume so that I can try and raise the rpm range up since the 7AFE's i smore torque oriented.
