Date Started: September 11 , 2009 Date Completed: September 11, 2009 Est. Days Worked on: 1 Comments: I hope this helps someone as it was surprising to me that our 3.5l v6 uses the same size* throttle body as the 5.6l v8 *the inlet, outlet, and throttle plate are the same size. there is however more meat on the 5.6l if someone were to bore it out. * I haven't looked into how the signaling is different between the two, if at all... I noticed they each have 6 connections. I assume two are for the electric motor and 4 for the position sensors. While they are oriented differently they both seem to have the same functions and should output the same result except for the possibility that the sensors send different ohms out for a given position. to adapt the VK56 throttle body to the VQ35 plenum, I was going to get an adapter machined, but easier, get a throttle body spacer and drill holes to match up to the VQ35 plenum. |

This is why you cant take off more than a couple MM from the VQ35DE throttle body
