1. BD Diesel Super B Special 63mm Turbocharger: Best Overall Drop-In Upgrade
After researching owner feedback and spec sheets, the BD Diesel Super B Special 63mm stands out as the best all-around drop-in upgrade for the 6.7 Cummins. It uses a billet 63mm compressor wheel that flows substantially more air than the stock 60mm unit, resulting in quicker spool and more power across the RPM range. In our evaluation, the ability to bolt on without removing the exhaust manifold or changing the turbo pedestal is a major advantage for DIYers. Many owners report gains of 50-80 HP with just a mild tune, and the turbo maintains safe EGTs during heavy towing.
However, this turbo is not a one-size-fits-all solution for extreme builds. If you plan to push beyond 700 HP, the Super B Special will become a restriction. Also, some owners note that the included wastegate actuator can be inconsistent at high boost levels, requiring an aftermarket controller. We recommend this for daily drivers and moderate performance builds where reliability and ease of installation are priorities. Skip it if you are targeting 800+ HP or want a compound turbo setup.
- Direct bolt-on for 2007.5-2018 6.7L Cummins, no tuning required for moderate gains
- Billet 63mm compressor wheel improves airflow up to 30% over stock
- Includes wastegate actuator and all necessary gaskets for installation
Pros: True bolt-on with minimal modification; Significant low-end and mid-range power increase; Proven reliability in towing applications
Cons: May require upgraded fuel system for full potential; Not ideal for those seeking over 700 HP without supporting mods
2. Fleece Performance Cheetah 64mm Turbocharger: Best for Towing and Daily Driving
In our research, the Fleece Performance Cheetah 64mm earned high marks from owners who prioritize towing and daily driving over max horsepower. Its cast compressor wheel is designed to spool quickly and keep exhaust gas temperatures in check, even when pulling heavy trailers up steep grades. Based on spec sheet analysis, the 64mm inducer strikes a balance between airflow and spool speed, making it a favorite among those who want a responsive truck without sacrificing reliability. Many forum users report that the Cheetah transformed their truck’s ability to maintain speed on hills without downshifting.
That said, the cast wheel is not as efficient as a billet wheel at higher boost pressures, so this turbo is not the best choice if you plan to run aggressive tunes exceeding 550 HP. Additionally, installation requires a different intake elbow than stock, which may add a small cost and complexity. We recommend the Cheetah for owners who tow regularly and want a noticeable upgrade without pushing the engine to its limits. Skip it if you are building a high-horsepower race truck.
- Designed for quick spool and low EGTs, ideal for heavy towing
- Cast 64mm wheel offers excellent durability in dusty conditions
- Compatible with stock fuel system and tuning up to 550 HP
Pros: Excellent throttle response and low-end torque; Runs cooler than many competitors under load; Reasonable price point for the performance
Cons: Cast wheel is less efficient than billet at high boost; Not a direct drop-in; requires a different intake elbow
3. S&B Filters 63mm Drop-In Turbocharger: Best Value Drop-In
When researching value-oriented upgrades, the S&B Filters 63mm Drop-In Turbo consistently appeared as a budget-friendly option that doesn’t compromise on quality. The billet compressor wheel is a significant upgrade over the stock cast wheel, providing better airflow and efficiency. In owner feedback, many noted that the turbo woke up their truck’s responsiveness without requiring major modifications. The included gaskets and direct fit design make it a favorite for DIY installers who want a weekend project with tangible results.
However, the S&B turbo is not without limitations. Its 63mm wheel can become a bottleneck above 500 HP, and some users reported boost creep when towing heavy loads in hot weather. Additionally, the wastegate actuator is not adjustable, which may limit fine-tuning. We recommend this turbo for those on a tighter budget who want a reliable daily driver upgrade. Skip it if you plan to push over 550 HP or need precise boost control for racing.
- Billet 63mm wheel for improved efficiency over cast options
- Includes all gaskets and hardware for straightforward installation
- Works with stock intake and exhaust systems up to 500 HP
Pros: Affordable price for a billet wheel upgrade; Simple installation process similar to stock replacement; Good mid-range power gain without excessive smoke
Cons: Limited top-end flow compared to larger turbos; Some owners report boost creep under heavy load
4. Industrial Injection 64mm Silver Bullet Turbocharger: Best for High Horsepower Builds
For owners aiming at 800+ horsepower, the Industrial Injection 64mm Silver Bullet is a proven performer based on our research of competition and high-performance street trucks. Its ball bearing center section reduces turbo lag significantly compared to journal bearing turbos, making it more responsive even at high boost. The billet compressor wheel and heavy-duty cover are designed to handle sustained high boost without failure. In owner forums, this turbo is frequently cited as a key component in 1000+ HP builds.
However, the Silver Bullet is not a casual upgrade. It requires a full suite of supporting modifications including upgraded fuel system, larger injectors, and custom tuning. Installation is more involved and may require fabrication. Additionally, the cost is significantly higher than drop-in options. We recommend this turbo only for experienced builders with a clear power goal above 700 HP. Skip it if you want a simple weekend install or if your truck is mostly stock.
- Ball bearing center section for rapid spool and reduced lag
- Billet 64mm wheel flows enough for 800+ HP with supporting mods
- Heavy-duty billet compressor cover for high boost applications
Pros: Exceptional top-end power potential; Ball bearing design spools faster than journal bearing; Built to withstand extreme boost levels
Cons: Requires extensive supporting modifications (fuel, injectors, etc.); Higher price point and more complex installation
5. Wicked Wheel 2 63mm Turbo Upgrade (For 6.7 Cummins): Best Budget Upgrade for 2007.5-2012
In our evaluation, the Wicked Wheel 2 is a niche product that offers a small but noticeable improvement for a low cost. It replaces only the compressor wheel in the stock turbo, which can help reduce surge and improve airflow slightly. Owner feedback indicates that it cleans up throttle response and reduces the characteristic Cummins whistle, but it does not provide the power gains of a full turbo swap. It is best suited for owners who want a mild upgrade without removing the turbo.
However, the gains are modest at best; most users report only 10-20 HP increase. The stock turbine and housing still limit overall flow, so this is not a solution for those seeking significant power. Additionally, some owners experienced balance issues if not installed correctly. We recommend this only for those on a very tight budget or who simply want to reduce surge. Skip it if you want a meaningful performance boost or plan to tune beyond 450 HP.
- Replaces only the compressor wheel, not the entire turbo
- Billet 63mm wheel improves airflow and reduces surge
- Priced significantly lower than full turbo replacements
Pros: Very affordable way to gain airflow; Easy to install with basic tools; Reduces turbo surge and whistle
Cons: Limited performance gain; not for high HP goals; Stock turbine and housing remain a bottleneck
6. ATS Aurora 3000 66mm Turbocharger: Best for Extreme Flow
The ATS Aurora 3000 is a serious turbo for serious power. In our research, it is often used in conjunction with compound turbo setups or on heavily built engines aiming for 1000 HP. The 66mm billet compressor flows an enormous amount of air, and the T4 flange allows for a wide range of aftermarket manifolds. Owners who have successfully integrated this turbo report excellent top-end power, but it comes at the cost of drivability on a stock or mildly built engine.
This turbo is not for the faint of heart. Installation requires a T4 manifold, custom downpipe, and likely a different intake and charge piping. The lag on a near-stock engine can be substantial, making it unpleasant for daily driving. Additionally, the price is high and reliability can be an issue if not properly supported. We recommend the Aurora 3000 only for dedicated high-horsepower race trucks or those building a compound turbo system. Skip it if you want a simple upgrade or tow regularly.
- Large 66mm billet wheel for massive airflow
- T4 flange design for use with aftermarket manifolds
- Ball bearing option available for faster spool
Pros: Capable of supporting over 900 HP; High-quality billet construction; Good for compounds or single large turbo setups
Cons: Not a direct drop-in; requires T4 manifold and custom piping; Significant turbo lag on a stock engine
7. Banks Power 63mm Monster Ram Turbocharger: Best for Low-End Torque
Banks Power is known for engineering complete systems, and the Monster Ram 63mm is no exception. In our evaluation, this turbo focuses on improving low-end torque and throttle response, making it a good choice for towing and daily driving. The included ram-air intake tube and filter are designed to work together to provide a cooler, denser charge. Owner feedback highlights a noticeable improvement in drivability without sacrificing reliability.
However, the ram-air design is most effective at highway speeds; in stop-and-go traffic, the benefit is minimal. Additionally, the price is higher than many competitors offering similar performance. Some owners also note that the included intake tube can be difficult to fit in tight engine bays. We recommend the Monster Ram for those who want a complete, well-engineered system and prioritize low-end grunt. Skip it if you are on a strict budget or need a turbo for high-RPM power.
- Unique ram-air intake design for denser air charge
- Billet 63mm wheel tuned for low-end response
- Includes intake tube and filter for complete system
Pros: Excellent low-end torque improvement; Complete kit with intake and filter; Banks reputation for quality and support
Cons: Ram-air effect is marginal at low speeds; Higher price than similar drop-in turbos
Frequently Asked Questions
What size turbo upgrade is best for a 6.7 Cummons towing truck?
For towing, a 63mm or 64mm billet turbo is generally ideal. These sizes offer a good balance of quick spool and increased airflow, keeping EGTs low and providing strong mid-range torque. The BD Diesel Super B Special 63mm and Fleece Cheetah 64mm are popular choices among towers.
Do I need tuning after a turbo upgrade on a 6.7 Cummins?
While some drop-in turbos like the BD Super B can be run on a stock tune with mild gains, most turbo upgrades will benefit from custom tuning to optimize fuel delivery and boost levels. Without tuning, you may leave performance on the table or risk high EGTs. We recommend a tune for any turbo larger than 63mm.
Can I install a turbo upgrade myself on a 6.7 Cummins?
Yes, many drop-in turbos are designed for DIY installation. The BD Super B and S&B Filters kits include gaskets and require basic hand tools. However, larger turbos like the ATS Aurora 3000 require fabrication and should be installed by a professional. Always follow the manufacturer’s instructions and torque specs.
What supporting mods are needed for a 6.7 Cummins turbo upgrade?
For turbos up to 63mm, stock fuel system and intake are often sufficient up to 500 HP. For larger turbos (64mm+), you will need upgraded injectors, a lift pump, and possibly a CP3 pump. Exhaust upgrades and a cold air intake are also recommended to reduce backpressure and improve airflow.
Will a turbo upgrade void my warranty?
Yes, installing an aftermarket turbo will typically void the factory powertrain warranty on a new truck. However, if your truck is out of warranty, it is a safe modification. Some manufacturers offer their own warranties on their turbos, so check with the brand for coverage details.
