In-depth discussion: 7.3 idi vs 7.3 Powerstroke

It is time to discuss the differences between these two diesel engines in detail. Here I will discuss their performance, reliability, durability, costs, fuel efficiency, and flexibility.

Performance

As far as performance is concerned, 7.3 Powerstroke performs much better than the 7.3 idi. The number one reason for Powerstroke’s better performance is its direct hydraulic fuel injector combined with the high-pressure oil pump.

Moreover, it also features a geometry turbocharger, and it is more capable than 7.3 idi’s turbocharger. Even later models feature an air to air intercooler that provides a large amount of cold air. Therefore, improved performance considerably over 7.3 idi.

7.3 Powerstrokes also perform better regarding other performance metrics such as power generation and fuel efficiency.             

Power

Power determines the capability of an engine.

The maximum horsepower of the 7.3idi is 185 hp, and torque is 338 lb-ft. On the other hand, 7.3 Powerstroke’s peak horsepower is 275 hp, and torque is 525 lb-ft. So, 7.3 Powerstroke is the clear winner here.

Moreover, if you want, you can boost the power of 7.3 idi using power-extending kits. However, it won’t perform like the Powerstroke. On the other hand, 7.3 Powerstroke offers more power customization options than 7.3 idi.

Engine cost

It is another important fact for engines. The engine’s overall reputation depends on it.

When it comes to the price of 7.3 idi and 7.3 Powerstroke, Powerstroke costs twice than the idi engine. 7.3 Powerstroke costs more because it is a computerized engine. Moreover, its parts are also expensive. So, it will cost more to repair.

Considering 7.3 idi, it doesn’t cost too much. It is a mechanical control engine. In addition, its parts are also not expensive. 

So, in the cost and price category, 7.3 idi wins over the 7.3 Powerstroke.  

Fuel economy

It is the most crucial matter of an engine. An engine loses its attraction if it is not fuel-efficient.

Thanks to the 7.3 Powerstroke for its superb fuel efficiency. It is the most fuel-efficient diesel engine in its category. 7.3 Powerstroke will give you 10+ mpg fully loaded, and 15+ mpg unloaded.

7.3 idi engine without turbocharging isn’t fuel-efficient like the Powerstroke. However, if you upgrade it with a turbocharger kit, then it will be fuel-efficient.   

Durability

As far as durability is concerned, 7.3 idi is a durable engine and runs on alternative fuels. Therefore, if you consider long-term durability, this engine is the best choice. It is tough to find a durable engine like 7.3 idi in its category.

On the other hand, 7.3 Powerstroke is a modern engine and features durable materials. For example, 7.3 Powerstroke uses cast iron for cylinder head and block. Therefore, it ensures long-term durability. Moreover, each cylinder uses six heads bolts which ensure better security.

Reliability

When it comes to reliability, 7.3 idi is one of the best out there. It will give you reliable performance in hot and cold weather.

However, if you are looking for a modern and highly reliable diesel engine, nothing can be better than 7.3 Powerstroke. It is a highly reliable diesel engine for every environment, thanks to its computerized mechanism. If your work environment requires better reliability, then 7.3 Powerstroke would be the best option for you.

Flexibility

Flexibility is another vital thing you should look for while choosing a diesel engine. It allows you to reconfigure the engine for better performance according to your requirements. With greater flexibility, you can boost power capacity, fuel efficiency, control mechanism, etc.

7.3 idi is an old engine and doesn’t offer too much flexibility. However, you can upgrade this engine power capability with a turbocharge kit.

On the other hand, 7.3 Powerstroke offers greater flexibility. For example, you can boost its power capacity, generate power faster, and you can upgrade its control mechanism. Moreover, there are different kits for upgrading this modern engine.

So, there is no doubt that 7.3 Powerstroke is more flexible than 7.3 idi.
