wrt vacuum routing w/o PS, you basically hook up the IAC valve under the throttle body just like a 3ee...I didn't use the vacuum 'log' mounted to the intake runners at all. 2 small lines go to the VSV on the pass side mount, and the 2 larger lines to the coolant bungs on the t-stat housing and rear water tube to the water pump.


Also there are 2 adjustments for idle speed on the throttle body. One is obviously the throttle plate allen head set screw and jam nut. The second is a screw oriented vertically as indicated by the red arrow. Threading the screw in and out just provides a restriction in a passage that bleeds air from upstream of the throttle plate to downstream. It is much easier to adjust the idle speed w/ this screw than the throttle plate.
