Where is the throttle body located on the 4G63? I see the air filter box leading somewhere.
Throttle body is where the silver pipe (right on the side of the valve cover) is going to. Airbox is attached to the MAF, to a pipe, to the turbo. 
This is probably the best route for anyone thinking about a turbo on the Zetec. 
Overflow is stock.
