Best Ford 2015 6.7 Powerstroke Turbo Upgrade
The 6.7L Powerstroke is a big engine in the truck department. You get the advantages of twin turbos because of the fact that it has two turbochargers (such as having a super responsive bottom with a strong top-end).
However, there is a catch: because the two wheels are attached to a single shaft, this turbo design sometimes suffers from failure.
So, how can you avoid being caught in the same trap? With a little bit of effort, you may create your own 6.7L Powerstroke Turbo Upgrade!
Normally, the 6.7L engine produces 440 HP at 2800 RPM. However, with a modification, you may significantly increase those figures (and more) while still keeping your motor running smoothly.
Let’s take a closer look at all of this information in the Powerstroke beginner’s guide, which is designed to assist you improve your MPG and enhance your Powerstroke’s “power stroke.” Let’s take a detailed look at everything in this research-driven beginner’s guide.

How Does The 6.7 Powerstroke Turbo Works?
The Powerstroke’s working style has evolved over time, depending on the model. The engine is equipped with a DualBoost turbocharger, for example.
This is different from a single sequential turbocharger or an SST in that it features two compressors.
As a result, the DualBoost turbocharger may supply the same characteristics and performance as a sequential twin-turbo system while taking up far less room.
Improved efficiency is obtained by the use of a unique exhaust system on the 6.7L Power Stroke diesel engine.
From the engine valley, the exhaust exit that is actually a manifold goes into the turbocharger’s position.
Gases naturally flow to the turbine housing from the exhaust manifold of conventional V-shaped engine turbochargers, and far less energy is lost than with traditional V-shaped engine turbochargers. Furthermore, because there is minimal energy loss through this path, considerably less exhaust plumbing is required.
If you walk to the intake side, you’ll see ports and manifolds that are outside of the engine block. When the turbocharger compresses air, it passes through an air-to-water CAC or Charge Air Cooler.
In total, there are two separate ways to cool the Powerstroke. The engine circuit works for a high-temperature system (which is why it’s called a “high-temp system”) and the CAC, along with the transmission cooler, fuel cooler, and EGR cooler.
Is It Possible To Improve The Performance Of A 6.7 Powerstroke By Upgrading Its Turbo?
Yes, the 6.7 Powerstroke is a powerful machine straight out of the box. But what if you want more power for your engine?
An increase in power in the back wheels as a result of an upgrade will always make your driving experience far more pleasurable than it was, and the push of the throttle will also provide much better outcomes.
Aftermarket modifications for the 6.7L Powerstroke are plentiful, as you’ll discover from our list of options. These modifications may significantly improve torque and horsepower output.
The 6.7L’s factory turbo is already a strong foundation. You get the boost quickly and efficiently, which is fantastic. If you want to add more power, the 2011-2014 Powerstroke vehicles with their turbos are worth considering because they tend to be somewhat restrictive.
The models we’re talking about aren’t only more prone to failure than previous ones, but they’re also less durable. So if you modify your approach based on the previous, you can just as easily accomplish it with a reputable aftermarket and better performance.
What Size Turbo is Required On a 6.7 Powerstroke?
The three different Turbos available for the 6.7 Powerstroke are the S363, S366, and S370. Let’s look at each of them in detail.
The S363 is an excellent option if you want a factory turbo replacement. This is adequate for someone who towing and driving on a regular basis. You’ll need to make minimal to no modifications to your car’s fuel system, yet it will still be capable of supporting higher power levels than other factory-style turbos.
You may make adjustments later on if you wish. The S363 can provide an Efficient Power Range of 450 to 750 HP for a high-pressure pump-upgrade.
The 65mm size is also an option. This turbo performs well if you want towing infrequently but frequently.
The only significant change is the elimination of some rear seats, which can be done in one or two steps. You have plenty of room for minimal/no changes as well. The Efficient Power Range here is 500 to 850 horsepower.
The 70mm option is the best for minimal towing usage. As a result, it may be utilized in a modified truck with a CP4 or twin pumps. However, this is also appropriate with minor injector modifications.
This is a wonderful choice if you don’t mind the wait for extremely powerful performance. It is efficient, with a Power Range of 600 to 950 horsepower.
How To Upgrade the Turbo On a 6.7 Powerstroke:
If you want to know how to upgrade the turbo on your 6.7L, this is the guide for you. It begins with an introduction to the upgrade and progresses through all four stages of reassembly in 4 easy steps.
Basics of The Upgrade
Remove the air filter to begin the installation. Remove the turbo intake pipes, intercooler boost tubes, and intake manifold tubing at the same time. This will aid in your access to both the turbo and pedestal.
When the exhaust inlet and outlet are disconnected, you can remove the turbocharger with its pedestal. It’s worth noting that a pedestal is built to allow it to function without the EPV.
Remove the housing of the compressor and replace the cast wheel with a machined billet now that you have the turbo on the bench. This is critical, and it’s known as “the literal heart” of this modification.
You will be happy with the Wicked Wheel2 or any other one for that matter, since it is lighter than the original cast wheel. The spooling will happen much more quickly as a result of the reduced weight. Because you get 10 blades in two different lengths rather than the factory’s 9 blades in one size, the former is considerably more aggressive.
By removing the upper section, we increase the amount of air that may be compressed on each revolution.
You can now remove the outlet flange by flipping it over and then removing the EBV flapper after you’ve fastened up the compressor side of the turbo.
Because the flapper and shaft are positioned in the middle of the exhaust flow, they obstruct it when open. In the worst-case scenario, this might indicate a poor engine performance.
To remove the assembly, you must grind away the rivets that keep it in place and pull out the shaft straight from the outlet flange.
Cleaning the mountings of your turbo one last time before reinstalling the outlet may be as simple or difficult as you want it to be. You can seal up any debris before attempting to clean up any mess by using a welder.
Here’s a step that might or may not get in your way of upgrading. You must repair any leaking pipes and collectors before reinstalling the new turbo. If you purchase one of the kits listed here, you will receive all of the necessary and replacement installation hardware. This can assist with rusted bolts that attach the pipes to the manifolds.
Now that you’ve removed the bolts, the up-pipes should come out of your vehicle rather easily. Then, check the donut gaskets. If those have broken and allowed modest to severe exhaust leaks, you may need to replace them with a new up-pipe kit.
It has bellows that can be used to expand and compress without causing harm to the gaskets, which you won’t find in the standard design.
This is why aftermarket components are preferable to original equipment, and the new arrangement will endure much longer than the previous one.
If you want to make things easier, install the passenger side of the up-pipe to the collector on the workbench before lowering it into position. Then, from the top end of the engine, you will lower it into place.
Remove your old turbo, clean the surfaces to be cleaned and use a little bit of sealant; then replace it with the new one. Now tighten all bolts on the exhaust manifold below the truck with your fingers. Then you’ll secure the collector hardware. Leave the manifesteright as finger-tight as possible until after you’ve installed the turbo and connected the exhaust outlet and intake in order for them to allow for necessary movements.
Before you reinstall the turbo, you can use a replacement pedestal with only the EBV actuator removed. Pedestals with several O-rings that seal themselves to the engine and turbocharger are recommended. New O-rings will prevent future oil leaks.
If the factory intake manifold boots are leaking, you may repair them with new silicone tubing before reinstalling the intake manifold. Finally, tighten all of the up-pipe-reaching-to-manifold mounting bolts on your turbo upgrade for a final drive under your truck!
It’s difficult to find the appropriate replacement 6.7L Powerstroke Turbo boost for the numerous alternatives available on the market.
There’s no need to go through all of the details in this book again. You should save yourself time and money (and maybe even some of your money) by using it as a reference while selecting a replacement or improved turbo kit for your 2017 6.7L Power Stroke engine.
The Ford MOTORCRAFT Performance M-Turbo-67 Turbo Kit for 15-21 Ford Powerstroke 6.7L is still the favorite, due to its excellent showcasing during testing and performance, which has shown good power gains with respect to the high-pressure fuel pump health.
So you’ve replaced the old factory turbo diesel with a dependable one. I’m sure your rear wheels run as smoothly now that they’ve been improved!
