The early AAZ pump with sprocket can be used on the 1.6. The later AAZ pump has a two part hub/sprocket and will not fit the 1.6 bracket. The delivery valves might not match and so they might need to be swapped or lines bent. The 1.6 injectors can be used. The AAZ injectors could also be used but they are dual stage and you would need to bend the fuel lines.
