This is for those who have Twin Screw or Root. How do deal with the Idle Speed Control (ISC). I noticed some delete it. What about the electronics and vacuum?
This is the IAC, If you deleted it your idle speed be greatly effected. We don't run IAC on our 2JZ set up and it seem to be fine. If you want your car to idle at 1200rpm. Then you can take this option out.

I think Brad best hook up that PCV to Plenum Vaccum..
The Little filter will do nothing..
Filter on the Drivers side breather,Yes..
But NOT on the PCV..
He will be holding to much crank pressure with it that way.
