Judging from the pictures the only difference I can see in piping is the intakes with the filters attached. The G they turn outwards into the wheel wells, while the Z they turn inside the FMIC pipeing and sit beside the intercooler. The pictures below you can see the rest of the piping coming around the front end looks identical.
This is the turn that will need to be modified to turn in where the G is straight
***Note the BOVs on this kit are located in the engine bay up top, I do not know why some kits they are mounted in the bumper, and others they are in the bay.
