you will need to use the D15B7 injectors
the D15B7 alternator uses a 4-rib belt and the D16A6 uses a 3-rib belt - swap your B7 crank pulley onto the A6
the D16A6 has the cooling fan switch on the back of the block - the B7 has it on the thermostat housing - need to install different connectors in order to plug it in
