Best Turbo for 6.7 Cummins 2021

(Last Updated On: July 11, 2021)

The turbochargers may seem complicated and confusing; however, they are a simple mechanical processing product that functions as a large fan. The turbo connects to the exhaust system and uses the high flow rate of exhaust to drive a turbine compressor, which pushes more air into the cylinders.

The original 5.9L Cummins engine was replaced by the 6.7L Cummins mid-2007, hence the 2007.5 formats. Additionally, companies built the 6.7L engine to match the performance of the GM and Ford models, which had surpassed the 5.9L Cummins. We have compiled some of the best turbo for 6.7 Cummins in the article. We suggest you have a close and detailed look at them.

Every new engine brings new problems. Problems began to surface not long after the introduction of the new 6.7L engine. The Check engine light was the first issue related to turbos. The P2262 diagnostic codes usually cause clogged kits. Porsche used the same kit in its original 6.7L Cummins engines. Porsche sued it for its Porsche 997. After many guarantee claims and some time, Cummins finally redesigned the kit and replaced the older ones. As a result, all Cummins manufactured between 2007 and 2012 have a factory-replacement. However, you can return the device with an aftermarket one if it is not.

The generation of power by an engine depends on the amount of oxygen that it can react with the fuel, so the more air a machine can “pumping,” the more force it has. There are two ways to get a lot of air into an engine: by increasing the internal volume to fit as much air as possible or by compressing the air so that it can get a lot into a small displacement. This last alternative is known as “supercharging” that includes compressing the air before putting it into the cylinders. For this purpose, different devices are on the market, but turbo is the priority.

In diesel mechanics, which work with excess air by definition, the turbo has been widely used for many decades; in fact, there is no model on the market today that incorporates a naturally aspirated diesel engine. However, in gasoline or gas engines, supercharging has not been very frequent, and only suitable for high-performance models or brands such as Saab, which always opted for small but high-performance engines, which is now called “downsizing.”

It uses variable-geometry technology and has moveable flaps within the compressor housing. These flaps open when there is enough pressure. It gives the charger a similar performance at low RPM. Once enough boost is given, they expand to allow for more power. This system has the advantage of being more compact and efficient.

Cummins had integrated exhaust-gas recycling (EGR) system into this kit, which causes the problem. It is where some of the exhaust gases get back into the intake. It allows burning more pollutants before they reach the exhaust pipes. It also helps comply with emission regulations codes. Diesel engines must use EGR to meet emission compliance.

EGR has one problem. It recycles dirty air back into charger units, which allows the pollutants to build up and cause them to clog. The system malfunction caused the vanes not to open correctly, resulting in a loss of performance and power and the P2262 diagnostic warning. Unfortunately, the turning on light indicates the damage at that time.

It is not difficult to replace your kit. It takes only 2 hours, a clean area, and the right tools. Before you begin this process, there are several things to do. These include unplugging your battery to ensure that you do not get electric shocks while working with the engine. Next, secure your motor so that it does not move during work. Finally, you need to make sure to have fluid collection pans under the engine to catch any oil or water that spills.
