This is what I eventually want to do. Right now I have the butterfly valve stuck open using wire. I also disconnected the vacuum components. All I have are the black and translucent vacuum lines going to the VCV with the ports to the EGR system blocked off and the atmosphere remaining operational. As far as I could see the only operation for the VCV is now for the transmission? Could you elaborate on the control for the crossover and resonance manifold?

I'm thinking when I remove the extension with the butterfly flap I will just try and find one of those cheesy cold air intake pipes with the right diameter and use a hack saw to cut it to length.

Thanks for the pictures and write-up and what a damn fine looking engine bay! CLEAN!!!!
