Update:
Finalized the Turbo Box design.
Air ducts under the car will pick up air and direct it to the back of the car between the tail lights in a low pressure area. The intercooler is the beige square color box and the turbo is the red circle. The inter-cooler will have its own separate box inside the bigger box. The turbo will feed air from the quarter vents through duct work.
I'm also going to have a small fan at the back of the box during low speed and stops to make sure no fumes get into the drivers area to promote air flow and cooling.
This is a cardboard mock-up the finish material will be aluminum.
I check to make sure there will be no blind spots while sitting in the drivers seat, Looking in the rear view mirror you can't even see the box.
EDIT:
Made a change and tapered the back of the box.
