One of the most popular repairs carried out by Powerstroke owners is a turbo replacement.

What Size of Turbo Do I Need?

Many considerations should be taken into account when calculating the size of the turbo suitable for your needs. You should take the specifications of your engine into account, in addition to the intended use of the engine. The most vital thing is to have a realistic mindset. For example, if you are turbocharging an engine rated at 200hp, it would be unrealistic to assume that it can produce 600hp. A 50-percent increase, on the other hand, is more realistic and will provide more satisfactory results.   

Another consideration is to keep your target horsepower in mind when choosing an appropriate turbocharger. Moreover, the intended use and application are also significant. For instance, a Bonneville car that is running for long straights will give more importance to horsepower at higher engine speeds. On the other hand, Indy cars continuously adjust the turbo according to the track length because a perfect match is essential for optimizing flow according to vehicle speeds and the specific engine.  

Why Did These Turbos Make Our List?

All the turbos on our list have been chosen keeping in mind the following considerations:


The market is flooded with various turbos manufactured by different companies. This can make choosing the right turbo for your 7.3L Powerstroke quite complicated. However, there are some well-known brands that specialize in the art of turbocharging. We recommend that you choose a brand that has a good standing in the market, as this will not only help you get a good-quality product but will also ensure satisfactory customer service.


Before spending your hard-earned cash on a turbo, sit down and determine the kind of power you want for your engine and if it is a realistic figure? Also, keep in mind the kind of driving you will be doing, as this will help you find the correct range of power for your engine.


Different turbos come with different price ranges. Keep your budget in mind while choosing a product to ensure that you get the right turbo.

Advantages and Disadvantages of Adding a Turbo to Your 7.3 Powerstroke

Here are the main advantages and disadvantages:


Turbo upgrades are very popular with diesel owners because of the following advantages:

Engine Becomes More Efficient

A turbocharger helps small engines produce more power. They utilize the engine’s hot air to spin the compressor wheel and draw in the outside air ,thus reducing the waste amount produced. This makes turbocharged engines more efficient.

Fuel Efficiency

Turbocharged engines use less gas, which makes them more fuel-efficient. This, in turn, makes them environment-friendly.


With a turbocharger, you can enjoy more horsepower, reduced exhaust gas temperatures, and run higher boost pressure.


Turbochargers have the following disadvantages also:  

Higher Repair Costs

Turbocharged engines have more components and are more complicated than a non-turbocharged engine. Although these engines are fairly reliable, their complicated design can cause the repair costs to increase considerably in case of a collision or if you experience some problems. Also, a turbocharger can put some components under considerable stress, which could reduce engine life.


A turbocharger provides more torque and enables the engine to respond better, which can make your vehicle more responsive. This, in turn, makes driving more fun and adventurous. We hope you will find the best turbo for your 7.3L Powerstroke from the above reviews so you can also enjoy the increased power to your engine.

People Also Ask

Before investing in a turbocharger, people like to research the products thoroughly. In addition, they also want to find answers to the following questions:

How Do I Know if My 7.3 Turbo is Bad?

There are many obvious signs that indicate the failure of the turbocharger. The first sign is a lack of power, and you may find that your car is not able to accelerate quickly. You will also see an engine light on the dashboard, alerting you to turbo failure. Your car will release excessive amounts of exhaust fumes and may make a loud whirring noise.   

What Happens When the Turbo Goes on a Diesel?

When the turbo goes on diesel, it causes an increase in the power output, lowers emission levels, and improves the efficiency of the engine.

Can a Turbo Engine Run Without the Turbo?

The turbocharger is driven by the exhaust fumes of the engine. This turbine device helps boost the pressure of incoming air into the engine, thus ensuring higher power output and improved engine efficiency. In case the turbocharger stops functioning, your vehicle will keep running, but it will perform poorly.
