to do the DPFI to MPFI swap, you need the intake manifold with sensors - Electronic Air Control Valve (EACV) and Intake Air Temp, new intake manifold gasket, throttle body (with TPS), fuel rail, fuel pressure regulator, fuel injectors, injector resistor box with wiring connectors, distributor, fuel line from filter to fuel rail, ECU and injector wiring with connectors
the intake manifold in your second picture appears to be from a DOHC ZC which won't work on the SOHC engine
