yea like i said it is a quick drawing and as far as the hose lines i said i would be for those who have removed their carbon canister and egr valve as well as the coolant bypass. Most people with the kind of power that would benefit from this upgrade would have already removed them anyways. as for the butterfly and shaft and spring assembly the housing is made exactly as for stock just modification to the shaft assembly needs to be done to accomadate for the larger butterfly. as for the bearings they are recessed in the throttlebody so if i did put them in you wouldnt be able to see that in the picture but on the drawing in the computer there is dimensions to accomadate for the bearings.
