1. Garrett GT37VMG Ball Bearing Turbo: Best Overall
The Garrett GT37VMG is a direct bolt-on ball bearing turbo that delivers quick spool and strong mid-range power. In our research, owner feedback consistently highlights its ability to improve towing performance without excessive exhaust gas temperatures. The ball bearing cartridge reduces friction, allowing the turbo to reach boost faster than journal bearing alternatives. Based on spec sheets, the 73mm inducer flows enough air for 600+ horsepower while maintaining driveability.
However, this turbo is not the cheapest option, and budget-conscious builders may find better value in journal bearing turbos. We recommend it for owners who prioritize response and towing capability over maximum peak power. If you plan to exceed 650 horsepower or run extreme tunes, a larger unit may be necessary.
- Ball bearing design reduces spool time and improves throttle response.
- Direct bolt-on for 2011-2019 6.7L Powerstroke, no modification required.
- Supports up to 650 horsepower with proper supporting mods.
Pros: Excellent low-end spool and transient response.; Proven durability in high-mileage towing applications.
Cons: Premium price point may not suit budget builds.
2. BD Diesel Stealth 64: Best for Towing
The BD Diesel Stealth 64 is a journal bearing turbo built specifically for towing and daily driving. Our evaluation of owner feedback shows it excels at building boost early, reducing lag when pulling heavy loads. The 64mm inducer and 1.0 A/R housing provide a good balance of airflow and spool characteristics. According to manufacturer specs, it can support up to 550 horsepower, making it a solid choice for moderate upgrades.
That said, if you’re chasing high horsepower numbers or frequently race, this turbo will be a bottleneck. It is best suited for owners who tow regularly and want improved performance without sacrificing reliability. For those seeking over 600 horsepower, consider a larger unit.
- Designed for low-end torque and towing reliability.
- Drop-in replacement with cast iron turbine housing for durability.
- Supports up to 550 horsepower, ideal for daily drivers.
Pros: Strong low-rpm boost for heavy towing.; Robust construction with high-quality materials.
Cons: Limited top-end power compared to larger turbos.
3. MDP Diesel 66mm S300SX-E: Best Value
The MDP Diesel 66mm S300SX-E offers a budget-friendly path to more power without sacrificing too much quality. Based on manufacturer specs and owner reviews, it flows enough air for 500-600 horsepower, making it a popular choice for mild to moderate builds. The journal bearing design is proven and reliable, though it may not spool as quickly as ball bearing turbos. Installation is straightforward with the included oil feed line.
However, this turbo may not hold up as well under extreme conditions or sustained high boost. It is best for owners on a budget who want a significant upgrade without breaking the bank. If you plan to push beyond 600 horsepower or race frequently, consider a more robust option.
- Affordable upgrade with proven S300 series performance.
- Bolt-on for 2011-2016 6.7L, includes new oil feed line.
- Supports 500-600 horsepower range.
Pros: Great power per dollar.; Easy installation with included hardware.
Cons: Journal bearing may have slower spool than ball bearing options.
4. Fleece Performance Cheetah 72mm: Best for High Horsepower
The Fleece Performance Cheetah 72mm is a high-flow turbo aimed at owners chasing big horsepower numbers. In our research, it can support over 800 horsepower with proper supporting mods. The billet compressor wheel offers improved strength and airflow over cast wheels. However, this turbo is not a direct bolt-on; it uses a T4 flange that typically requires a custom up-pipe or adapter, increasing installation complexity and cost.
Due to its large size, it has noticeable lag at low RPMs, making it less suitable for daily driving or towing. We recommend this turbo for dedicated performance trucks used for racing or sled pulling. If you need a streetable turbo with quick response, look elsewhere.
- Large 72mm inducer for high airflow up to 800+ horsepower.
- T4 flange requires custom piping or adapter.
- Includes billet compressor wheel for strength.
Pros: Massive top-end power potential.; Billet wheel is more durable than cast.
Cons: Not a direct bolt-on; requires fabrication.; Significant lag below 2500 RPM.
5. ATS Aurora 3000: Premium Choice
The ATS Aurora 3000 is a premium ball bearing turbo that combines quick spool with high durability. Based on owner feedback and manufacturer data, it delivers strong mid-range power and can handle up to 650 horsepower. The billet compressor wheel and ball bearing cartridge are designed for longevity. Installation is straightforward as a direct bolt-on.
Its main drawback is the price, which is significantly higher than journal bearing options. This turbo is best for owners who want a top-tier product and are willing to pay for it. If you are on a tight budget, the value proposition may not be as strong.
- Ball bearing turbo with billet compressor wheel.
- Bolt-on for 2011-2019 6.7L, no modifications needed.
- Supports up to 650 horsepower with excellent spool.
Pros: Superior build quality and materials.; Excellent customer support and warranty.
Cons: Higher cost than many competitors.
6. Sinister Diesel 66mm Billet Turbo: Reliable Workhorse
The Sinister Diesel 66mm Billet Turbo offers a billet compressor wheel at a competitive price. In our evaluation, it provides decent performance for mild upgrades up to 550 horsepower. The billet wheel is stronger than cast, which can help with longevity. Installation is straightforward as a direct bolt-on.
However, we found mixed owner feedback regarding quality control, with some units having issues out of the box. This turbo is best for owners who want a budget billet option and are willing to accept some risk. For those seeking maximum reliability, a more established brand may be preferable.
- Billet compressor wheel for improved strength.
- Direct bolt-on for 2011-2016 6.7L.
- Supports up to 550 horsepower.
Pros: Billet wheel is more durable than cast.; Good spool characteristics for daily driving.
Cons: Some owners report inconsistent quality control.; Not ideal for high-boost applications.
7. K&N 63-1570 Turbo Kit: Complete Kit
The K&N 63-1570 Turbo Kit is a complete package that includes the turbo, intake tube, and charge pipes, making it a convenient upgrade for mild power gains. Based on our research, it supports up to 450 horsepower, which is suitable for those seeking a modest improvement. The journal bearing design is reliable but not as responsive as ball bearing options. Installation is simplified by the included components.
However, this kit is not for those chasing high horsepower; its 63mm inducer limits airflow. Additionally, some owners have reported fitment issues with the charge pipes. We recommend this kit for owners who want a simple, complete upgrade without the need to source additional parts. If you plan to exceed 450 horsepower, look for a larger turbo.
- Complete kit includes turbo, intake tube, and charge pipes.
- Direct bolt-on for 2011-2014 6.7L.
- Supports up to 450 horsepower.
Pros: All-in-one solution simplifies installation.; K&N brand recognition and support.
Cons: Lower power ceiling compared to dedicated turbos.; Some owners report fitment issues with charge pipes.

What is the best turbo upgrade for a 6.7 Powerstroke without breaking the bank?
For budget-conscious owners, the MDP Diesel 66mm S300SX-E offers a great balance of performance and value. It supports 500-600 horsepower and is a direct bolt-on. While it uses a journal bearing, it provides reliable power gains at a lower cost than ball bearing options.
Will a turbo upgrade void my warranty?
Yes, installing an aftermarket turbo can void your vehicle’s powertrain warranty, especially if the upgrade is not approved by the manufacturer. It’s important to check with your dealer or warranty provider before making modifications. Some tuners offer plug-and-play options that may be less invasive, but there is always a risk.
Do I need supporting mods with a turbo upgrade?

Common supporting mods include a tuner or programmer, upgraded fuel system, larger exhaust, and a cold air intake. Failing to upgrade supporting components can lead to high exhaust gas temperatures and engine damage.
How much horsepower can I expect from a turbo upgrade?
Horsepower gains vary widely depending on the turbo size and supporting mods. A mild upgrade like the K&N kit may add 50-100 horsepower, while a large turbo like the Fleece Cheetah can support over 800 horsepower. Realistic gains for most streetable upgrades are between 100 and 200 horsepower over stock.
Is it difficult to install a turbo on a 6.7 Powerstroke?
Installation difficulty ranges from moderate to challenging. Direct bolt-on turbos like the Garrett GT37VMG are easier for experienced DIYers, requiring basic tools and mechanical knowledge. Larger turbos that require custom piping, such as the Fleece Cheetah, demand fabrication skills and are best left to professionals.
