Nope... the only thing the earlier IDI (In-Direct Injection) 7.3's have in common with the Powerstroke 7.3's is the displacment. The PSD's are direct injection, as in, the injector is injecting the fuel directly into the piston/cylender chamber, where as the IDI's have a 'pre-injection chamber' that the injector sits in, with a port into the cylender chamber.
Later 94.5 PSD injectors would fit, but are going to limit fuel flow, they are designed for non-intercooled motors.
