What is the Best Turbo for the 6.7 Cummins?

If you are looking for the best turbo for your 6.7 Cummins, there is a wide variety of options available to suit your specific needs. From stock turbos that offer good performance and reliability to aftermarket units with larger compressor wheels and higher flow rates, picking the right one can be daunting. To get the most out of your truck, it’s important to consider both power output and desired characteristics such as response time or fuel economy when selecting a turbocharger.

For maximum performance from your 6.7 Cummins engine, we recommend choosing a Holset HE351CW or HE300VG turbo with an upgraded compressor wheel size such as an 85mm or 90mm billet wheel for increased flow rate – perfect for getting more air into the cylinders at higher RPMs and allowing you to extract all the horsepower potential of your engine!

What Turbo is in a Stock 6.7 Cummins?

The 6.7 Cummins is an extremely powerful and dependable engine, designed for heavy-duty commercial applications such as semi-trucks and large agricultural vehicles. It comes equipped with a VGT turbocharger (variable geometry turbo) which utilizes a series of vanes to optimize the air pressure ratio within the engine. The turbo provides additional power by forcing more air into the cylinders than would normally be possible in a naturally aspirated engine.

This extra boost increases fuel efficiency and performance, while also reducing emissions significantly. In addition to its reliable performance, this type of turbo also offers superior durability when compared to other types of turbos available on the market today.

How Much Boost Can a Stock 6.7 Cummins Turbo Handle?

The 6.7 Cummins turbo can handle quite a bit of boost, depending on the modifications that have been made to it. Generally speaking, you should expect up to 40 pounds of boost with a stock 6.7 Cummins turbo setup. That said, if performance upgrades are implemented like modified fuel injectors and an upgraded exhaust manifold, then you could see gains up to 50lbs of boost or more in some cases.

It is important to note that running higher levels of boost will require additional modifications such as stronger pistons and connecting rods along with other internal engine components in order for your truck to achieve maximum power output without suffering damage over time due to increased strain on the engine’s internals. With proper maintenance and tuning, however, you can get significant increases in horsepower and torque from increasing the amount of boost provided by your 6.7 Cummins Turbo!

How Big is Stock Turbo on 6.7 Cummins?

The 6.7 L Cummins Turbo Diesel engine comes with a stock turbo that is sized at 68mm from the factory. This can provide up to 35 PSI of boost, producing impressive levels of power and performance for your diesel vehicle. The stock turbo also has variable geometry turbine (VGT) technology which helps optimize exhaust flow and reduce emissions while providing more efficient use of fuel at lower speeds.

Additionally, the stock turbo on the 6.7 Cummins utilizes an electronically actuated wastegate that allows it to precisely regulate boost pressure while protecting against over-boost conditions and preserving engine longevity and reliability.

6.7 Cummins Turbo Upgrade With Exhaust Brake

Upgrading your 6.7 Cummins turbo with an exhaust brake is a great way to improve the performance of your truck and reduce wear on braking components. An exhaust brake helps slow down the vehicle by redirecting some of the engine’s exhaust gases back through the turbine, creating drag against the spinning blades that slows down the engine’s output speed while also providing improved power at lower RPMs. This not only provides better braking control, but it can also help extend brake life and provide additional fuel economy benefits as well.

6.7 Cummins Vgt Turbo Upgrade

If you’re looking to increase performance and power on your 6.7 Cummins, consider a VGT turbo upgrade. This is a great way to improve the overall engine efficiency of your vehicle by replacing the stock turbocharger with an aftermarket upgraded version for improved boost response, increased airflow and faster spool-up times. It also helps reduce backpressure and increases exhaust flow which can lead to more horsepower being generated from the motor.

A VGT turbo upgrade is sure to give your 6.7 Cummins that extra kick it needs!

Best Vgt Turbo for 6.7 Cummins

If you’re looking for the best VGT turbo for your 6.7 Cummins, then look no further than the BorgWarner S300SX3 Turbocharger. This turbo is designed to provide increased airflow and boost pressure without compromising durability or reliability, making it an ideal choice for those who want maximum performance from their Cummins engine. The S300SX3 also comes with a ceramic-coated turbine housing that helps reduce EGTs (exhaust gas temperatures), allowing for more efficient combustion and less smoke production.
