Why Upgrade Your 2019 6.7 Cummins Turbo?

So, why should you even consider a turbo upgrade for your 2019 6.7 Cummins? The stock turbocharger on these trucks is pretty good, don't get me wrong. But, like most things, there's always room for improvement. The primary reason for upgrading is to enhance overall performance. This translates to increased horsepower, torque, and a more responsive driving experience. Upgrading your turbocharger allows you to push more air into your engine, resulting in better combustion and, ultimately, more power. This is particularly noticeable when towing heavy loads or accelerating on the highway. Another advantage is the potential for improved fuel efficiency. By optimizing airflow, you can potentially see an increase in miles per gallon, saving you money at the pump. Furthermore, a turbo upgrade kit can improve the longevity of your engine. A high-quality upgraded turbo can run at lower stress levels compared to a stock unit pushed beyond its limits. A well-matched turbo can also lower exhaust gas temperatures (EGTs), which is crucial for the engine's health and durability. Think about it: a cooler running engine means less wear and tear, and a longer lifespan for your trusty Cummins. Beyond performance, a turbo upgrade can also change the sound of your truck. Many kits produce a more aggressive and satisfying whistle, giving your rig a more authoritative presence on the road. It's a win-win, really: you get more power, potentially better fuel economy, and a cooler-sounding truck. Now, who wouldn't want that? Finally, upgrading the turbo is a great starting point if you plan on adding other performance modifications, such as injectors or a programmer, since your turbo helps handle more air flow.

Choosing the Right 2019 6.7 Cummins Turbo Upgrade Kit

Alright, so you're sold on the idea of a turbo upgrade. Now comes the fun part: choosing the right kit! With a plethora of options on the market, it can be a bit overwhelming. But don't worry, we're here to help you navigate the choices. First and foremost, you need to consider your goals and driving style. Are you looking for a daily driver that's a bit more spirited? Or are you aiming for a high-horsepower build for racing or heavy towing? Your answer will significantly influence your turbo selection. For daily drivers and light towing, a drop-in replacement turbo is often a great choice. These kits are designed to bolt directly onto your existing exhaust manifold and downpipe, making installation relatively straightforward. They typically offer a noticeable improvement in power and responsiveness without requiring extensive modifications. If you're planning on pushing your Cummins to its limits with heavy modifications, you'll need to step up to a larger turbo. These kits often include a new exhaust manifold, which is designed to handle the increased airflow. They can deliver massive power gains, but they also require more extensive installation and may not be ideal for a daily driver. When it comes to brands, a few names consistently come up as top contenders in the 2019 6.7 Cummins turbo upgrade market. Companies like BorgWarner, Garrett, and Fleece Performance Engineering are known for their high-quality products and innovative designs. Researching different brands and reading reviews from other Cummins owners is a great way to gauge the performance and reliability of various kits. Pay close attention to the turbo's specifications, such as the compressor wheel size, turbine wheel size, and the A/R ratio of the exhaust housing. These specs will directly impact the turbo's performance characteristics. Also, be sure to check what components are included in the kit. Does it come with all the necessary hardware, such as gaskets, studs, and oil feed lines? A kit that includes everything you need will save you time and hassle during installation. Consider the material of the turbocharger, with many made of either cast iron or stainless steel. Stainless steel units typically offer better corrosion resistance.

Installation Process: A Step-by-Step Guide

Okay, so you've got your new turbo upgrade kit in hand. Now comes the exciting part: installation! While the exact process will vary slightly depending on the kit you choose, here's a general overview of the steps involved. Before you begin, gather all the necessary tools and supplies. You'll need basic hand tools, such as wrenches, sockets, screwdrivers, and pliers. You'll also need a torque wrench to ensure that all the bolts are tightened to the proper specifications. Safety first! Disconnect the negative battery terminal to prevent any electrical mishaps. Then, jack up the front of your truck and secure it with jack stands. This will give you plenty of room to work under the hood. Locate the existing turbocharger. It's usually mounted near the exhaust manifold. Disconnect the intake and exhaust pipes from the turbocharger. Be careful when removing the exhaust pipes, as they can be hot even after the engine has cooled down. Next, remove the oil feed and drain lines from the turbocharger. These lines supply oil to lubricate the turbo's bearings. Now, you can remove the turbocharger from the engine. It's held in place by several bolts. Be sure to label the bolts as you remove them so you know where they go during reassembly. Once the old turbo is out, carefully install the new turbocharger. Follow the instructions that came with your kit. Make sure to torque all the bolts to the manufacturer's specifications. Reconnect the oil feed and drain lines, and then reattach the intake and exhaust pipes. Once everything is connected, double-check all your connections. Ensure that everything is tight and secure. Reconnect the negative battery terminal. Start the engine and let it idle for a few minutes. Check for any leaks. If you don't see any leaks, take your truck for a test drive. Gradually increase the throttle, and listen for any unusual noises. You may need to have your truck's computer flashed after installing a new turbo, depending on the kit. Many kits come with instructions on how to do this. Remember, if you're not comfortable working on your truck, it's always best to have a qualified mechanic perform the installation. Professional installation will ensure that the turbo is installed correctly and that your engine is protected.

Important Considerations Before You Upgrade

Before you jump into a 2019 6.7 Cummins turbo upgrade, there are a few important considerations you should keep in mind. First, consider the supporting modifications. A turbo upgrade is often just the beginning. To fully realize the benefits of your new turbo, you may need to upgrade other components, such as your fuel injectors, fuel pump, and intercooler. These upgrades will help to ensure that your engine can handle the increased airflow and power. Additionally, you may need to have your truck's computer tuned after installing a new turbo. A custom tune can optimize your engine's performance and ensure that everything is running smoothly. Second, consider the warranty implications. Installing a turbo upgrade kit may void your truck's factory warranty. Be sure to check your warranty documents and understand the potential risks before proceeding. Third, consider your budget. Turbo upgrade kits can vary in price, from a few hundred dollars to several thousand. Factor in the cost of the kit, installation, and any supporting modifications that you may need. Fourth, consider the emissions regulations in your area. Some turbo upgrade kits may not be street legal, depending on your location. Make sure that the kit you choose complies with all applicable regulations. Finally, be sure to use high-quality parts. The quality of your turbocharger and other components will directly impact the performance and reliability of your engine. Look for reputable brands and read reviews from other Cummins owners before making your purchase.

Maintaining Your Upgraded Turbo

Once you have installed your new 2019 6.7 Cummins turbo, proper maintenance is key to keeping it running smoothly and extending its lifespan. One of the most important things you can do is to change your engine oil and filter regularly. Upgrading to a higher-quality oil, such as full synthetic, is also a good idea. This will help to protect your turbocharger's bearings and other internal components. Allowing your engine to warm up before driving is essential, especially on cold mornings. This gives the oil a chance to circulate and lubricate the turbocharger. Avoid revving the engine hard until it has reached its operating temperature. When you're done driving, let your engine idle for a few minutes before shutting it off. This allows the turbocharger to cool down gradually, which helps to prevent oil coking. Oil coking occurs when oil gets too hot and forms deposits inside the turbocharger. Avoid overloading your engine. When towing heavy loads, be sure to stay within your truck's towing capacity. Overloading your engine can put extra stress on the turbocharger and other components. Regularly inspect your turbocharger for any leaks or damage. Check the intake and exhaust pipes for any cracks or loose connections. If you notice any problems, have them addressed by a qualified mechanic as soon as possible. By following these simple maintenance tips, you can help to ensure that your upgraded turbocharger provides years of reliable service.
