Here's a breakdown:
1994 Ford 7.3L IDI:
* Indirect Injection: Fuel is injected into a pre-chamber, then ignited.
* Naturally Aspirated: No turbocharger.
* Lower Power Output: Compared to the Power Stroke.
* Simpler Design: Fewer parts, often considered more reliable.
* Found in: F-Series trucks, E-Series vans, and some other Ford vehicles.
1994 Ford 7.3L Power Stroke:
* Direct Injection: Fuel is injected directly into the combustion chamber.
* Turbocharged: Increases power output.
* Higher Power Output: More power than the IDI engine.
* More Complex Design: More advanced technology, potentially more maintenance required.
* Found in: F-Series trucks and E-Series vans.
Important Note: Although both engines share the 7.3L displacement, they are significantly different in design and performance. You need to be clear about whether you are referring to an IDI or a Power Stroke engine when discussing a 1994 Ford 7.3L diesel.
