Garrett GT Series Turbos

Diving into the realm of Garrett GT Series Turbos, we find a lineup designed to boost the performance of diesel engines with remarkable efficiency and reliability. We're looking at a range that's engineered to maximize power while minimizing lag, giving us the freedom to push our engines to their full potential.

Garrett's ball bearing technology is at the heart of the GT Series, providing us with reduced friction and quicker spool times compared to traditional journal bearings. This translates to a more responsive throttle and a significant increase in performance. We're not just getting better power; we're also ensuring the longevity of our turbo system.

Moreover, we can't overlook the importance of the GT Series' advanced aerodynamics. The compressor and turbine wheel designs are optimized for the best possible airflow, allowing us to achieve higher boost pressures and more efficient intercooling. This means we're extracting maximum energy from every drop of fuel, and that's the kind of liberation we're after.

To tailor to our specific needs, the GT Series offers a range of sizes and configurations. Whether we're upgrading a light-duty pickup or a heavy-duty workhorse, there's a GT turbo that's ideal for our setup. We're not just upgrading; we're transforming our diesel engines into powerhouses.

BorgWarner EFR Series

While the Garrett GT Series sets the bar high for diesel engine turbocharging, the BorgWarner EFR Series steps up as a formidable contender, offering a suite of features that cater to the most demanding performance enthusiasts.

BorgWarner's EFR (Engineered for Racing) turbochargers are the result of meticulous engineering, designed to provide an unparalleled combination of advanced aerodynamics and materials.

We're talking about a range that includes low inertia Gamma-Ti turbine wheels and shaft assemblies for quick boost response. Moreover, they're equipped with dual ceramic ball bearing cartridges that enhance durability and reduce friction. This translates to faster spooling and a significant reduction in turbo lag, freeing up the engine to reach peak performance rapidly.

The EFR Series also boasts integrated compressor recirculation valves (CRV) and boost control solenoids, streamlining installation and optimizing turbocharger efficiency. It's an all-in-one solution that appeals to those who prioritize ease of upgrade and maintenance.

We mustn't overlook their impressive range of sizes and configurations, which enable precision tuning for specific applications, whether for street-legal upgrades or for full-blown competition rigs. When you're aiming to push your diesel to its limits, the BorgWarner EFR Series represents a high-end investment that can deliver the liberation from stock performance you crave.

Holset Cummins Performance

Holset's line of turbochargers, renowned for boosting Cummins diesel engines' performance, exemplifies the synergy between manufacturer and powerplant through precision engineering and robust design. These turbochargers aren't just components; they're the heart of an engine's ability to breathe fire, push limits, and conquer the road. We understand that for our audience, seeking liberation means breaking free from stock limitations and embracing the full potential of their diesel workhorses.

When considering Holset turbochargers for Cummins engines, we're looking at:

  1. Unmatched Spool Times: Quick turbo spool-up slashes lag, delivering immediate power and gratifying acceleration.
  2. Increased Efficiency: Optimized air flow allows for better combustion, more horsepower, and greater torque, all while maintaining fuel economy.
  3. Durability Under Stress: Holset turbos are engineered to withstand the rigors of high-performance demands, ensuring reliability even under extreme conditions.

Precision Turbo Upgrade Options

Turning our focus to Precision Turbo upgrade options, we find a range of aftermarket solutions designed to elevate diesel engine performance through meticulous craftsmanship and cutting-edge technology. We're talking about robust upgrades that not only enhance power output but also improve efficiency and reliability.

Precision Turbo, known for their engineering prowess, provides a variety of turbos tailored to meet specific performance goals. Their lineup includes options like the Street and Race series, each engineered to support different horsepower ranges while maintaining optimal spool characteristics. We're particularly impressed with their ball bearing turbos which offer reduced turbo lag and exceptional transient response, allowing for quicker acceleration and more agile power delivery.

For those seeking substantial power gains, we recommend considering Precision's larger frame turbos, which are capable of supporting significant horsepower increases. These upgrades often involve a billet compressor wheel, which is lighter and stronger than traditional cast wheels. This translates to faster spool-up times and a broadened efficiency range.

Let's not forget, a turbo upgrade isn't complete without tuning the fuel system to match the increased air delivery. We must ensure the engine management system is recalibrated to optimize the air-fuel ratio, making the most of the turbo's potential while guarding against over-stressing the engine components.

Precision Turbo upgrades are an investment in unleashing diesel engine capabilities, catering to those who demand the freedom of raw power and improved performance.

Mitsubishi TD Series Enhancements

Delving into the Mitsubishi TD Series turbochargers, we encounter a suite of enhancements designed to boost diesel engine performance with remarkable precision and efficiency. These turbochargers are meticulously engineered to unleash your engine's full potential, delivering power and liberation from factory constraints.

When we consider the Mitsubishi TD Series upgrades, we're not just talking about marginal improvements. We're looking at substantial leaps in performance that will make your diesel heart race. Here's what we can achieve:

  1. Improved Airflow Efficiency: The TD Series turbochargers feature optimized compressor wheel designs that significantly increase airflow, minimizing turbo lag and enabling your engine to breathe freely, translating to quicker throttle responses and a surge of power when you demand it.
  2. Enhanced Durability: Constructed with robust materials, these turbochargers are built to withstand the high temperatures and pressures inherent in diesel applications, ensuring longevity and reliability even under the most demanding conditions.
  3. Customization Potential: These turbochargers come with a range of housings and actuator options, allowing for precise tuning to match your engine's characteristics and your performance aspirations, offering a tailored boost experience that's second to none.

We understand the thirst for freedom that comes with turbo upgrades. It's not just about raw power; it's about transforming your diesel engine into a liberated force, unrestrained by the limits of stock settings. With the Mitsubishi TD Series turbochargers, we're not just enhancing engines; we're unlocking a new realm of diesel dominance.


In conclusion, we've explored the top turbo upgrades that can breathe new life into diesel engines.

From Garrett's GT series for robust power to the BorgWarner EFR's innovation, Holset's Cummins-tailored performance, Precision's precise boost control, and Mitsubishi TD's reliable enhancements, there's a turbo for every need and budget.
