After upgrading to the DVDT Fab Intake manifold and the Q45 TB, I was tired of idle issues, so I decided to take a stab at rigging up a universal ISC motor to put some drivability back into the car.
Obviously the ports go to a before / after throttle plate bung of some kind so that the motor can allow / not allow air to bypass the throttle.
Thing worked wonders.
Essentially, I took the underside (ISC / FIAV) portion of the Tb off, sawed off the FIAV, welded the now gaping channels closed, and milled out a plate and threaded some fittings in place. Pretty easy. Only took an afternoon in a machine shop.
