There's some small errors on this thread. To me worth mentioning an to others not worth mentioning or they would have said so. Anyway.

What makes the outer set of secondary plates ( the number two seocndary throttle valves) move is the DOUBLE THROTTLE DIAPHRAM in conjunction with the water thermo valve which is NOT the water thermowax device with the fast idle cam etc.

On a turbo thottle valve the number two secondary valves were designed to move/open slower than the number one secondary throttle valves. Driveablility thing. There is on a USA turbo throttle valve a dashpot who's plunger rides on a flat black cam and the dashpot is what makes the outer set (the number two secondary throttle plates) open a tash slower than the number one secondary throttle plates.

I find it hard to believe the JDM's have five plates and they all work together when they were built stk. But I never owned a JDM so take that for what its worth.
