If you are doing S13 to S13 swap there is already a hole there that you just need to make larger. The hole on USDM cars is about 2 inches in diameter and would be found under the intake box area. There is an embossed area resembling the shape of a heart. Cut out that heart shape and both the BOV/recirc line and intercooler piping can fit through it.
