Types of Sr20de Headers

An SR20DE header is a part of the exhaust system in a vehicle. Its main job is to carry exhaust fumes away from the engine and release them into the air. This header is designed for Nissan's SR20DE engines, commonly found in various Nissan and Infiniti models. These headers improve engine performance by increasing airflow. As a result, the car gets better power and fuel efficiency. There are different types of SR20DE headers, each designed for a specific purpose.

• SR20DE Long Tube Headers: Long tube headers are designed to provide maximum performance gains. They are called long tube headers because they have long primary pipes that extend far into the exhaust system. This design allows for better airflow and reduces exhaust back pressure. As a result, more power is generated from the engine. These headers also improve the sound of the vehicle.
• SR20DE Shorty Headers: Shorty headers are smaller in size compared to long tube headers. The primary pipes of shorty headers are shorter and measure about 12 to 16 inches. Like long tube headers, shorty headers also improve engine performance by increasing airflow. However, the performance gains are not as significant as those achieved using long tube headers. Shorty headers are more affordable and easier to install. For this reason, many car owners prefer shorty headers over long tube headers.
• SR20DE Turbo Manifold Headers: Turbo manifold headers are designed for vehicles equipped with turbochargers. The primary pipes of turbo manifold headers connect the engine's exhaust ports to the turbocharger. These headers allow exhaust gases to flow into the turbocharger, where they spin the turbine blades. As a result, more boost pressure is generated by the turbocharger.
• SR20DET Headers: These headers are designed for Nissan's SR20DET engines, which are similar to the SR20DE headers. The only difference is that the SR20DET engine is a turbocharged version of the SR20DE engine. Like the SR20DE turbo manifold headers, the SR20DET headers also come with turbo manifold headers that connect to the turbocharger.

Specification and Maintenance of Sr20de Header

Here are the specifications of the SR20DE header:

• Materials: The materials used in the construction of headers are very important. This is because the material used influences the performance of the header. It also influences its durability and effectiveness. Cast iron is one of the most common materials used for the construction of SR20DE headers. Cast iron is known for its durability and effectiveness. It is also resistant to high temperatures. Another material used in the construction of the SR20DE header is steel. Steel offers the benefit of being lightweight.
• Number of tubes: The number of tubes in the header is also an important specification to note. The number of tubes in the header varies. This is because the number of tubes is dependent on the design of the header. Some of the designs include 4-2-1 and 4-1 designs. The 4-2-1 design header has two tubes that merge into one. While the 4-1 design has all the tubes merging into a single tube.
• Size: The size of the SR20DE headers affects the performance. Headers come in different sizes. The size of a header can be determined by the diameter of the primary tubes and the collector. It is important to note that the size of the header affects the exhaust flow. Larger headers improve performance by increasing the flow of exhaust. Smaller headers on the other hand reduce the flow of exhaust.

It is important to maintain the SR20DE header. Proper maintenance of the header helps to improve its performance and also increase its durability. One of the easiest ways to maintain the SR20DE header is by regularly inspecting it. During the inspection, users should look out for rust damage, cracks and leaks. In case of any damage, appropriate repairs should be carried out. Cleanliness is also an important aspect of maintaining the SR20DE header. Users should ensure that the header is clean. This will prevent the build-up of carbon and other debris. In case the carbon build-up is too much, users can use a header cleaner to remove it. Another important aspect of maintaining the SR20DE header is ensuring that the bolts and flanges are tight. Loose bolts can cause leaks.

How to Choose an SR20DE Header

Choosing the right headers for Nissan SR20DE engines can be a daunting task. There are virtually endless possibilities and variations to consider. Every car is different, and every driver has a different expectation from their car. However, here are a few tips to help narrow down the choices.

• Consider the Car Make and Model: It is important to consider the car make, model, and year of production before choosing any SR20DE headers. This is because, while most headers are designed to fit a wide range of vehicles, they may not fit perfectly in every car. For example, the headers may fit perfectly in a Nissan 240SX but have difficulty fitting in a Nissan Sentra. Therefore, it is important to consider the specific vehicle before choosing an SR20DE header.
• Consider Performance Expectations: SR20DE headers come in various designs optimized for different levels of performance. For example, some headers are designed to improve low-end torque, while others are designed to improve high-end power. It is important to consider what type of power the user wants from the engine before choosing a header. For normal street driving, a header that offers a good balance of torque and power is recommended. But for track use or spirited driving, a header that focuses more on high-end power is the best choice.
• Consider Legal Requirements: When choosing an SR20DET header, it is important to consider the legal requirements in a particular area. Some headers are designed to be emissions compliant, while others are not. Emissions-compliant headers are typically quieter and do not produce as much emissions as non-compliant headers. Non-emissions-compliant headers, on the other hand, offer the ultimate in performance but can be quite loud and produce more emissions. Before choosing any header, be sure to verify the emissions regulations in the area.

How to DIY and Replace SR20DE Header

Replacing an SR20 header can be a difficult task, especially for those who are not familiar with car parts. Before replacing the SR20DE header, it is important to know which type of header is compatible with the vehicle. This is because there are different types of SR20 headers, as mentioned above. The tools needed for the job must be available.

Below are the steps to DIY and replace an SR20DE header:

• Prepare the car

  To replace the SR20DE header, the car should be parked on a flat surface. The car battery should be disconnected, and the ignition should be turned off. This is to prevent the car from starting while working on it. The hood should be raised, and the hood prop should be used to hold it in place.

• Gather the necessary tools

  Before replacing the SR20DE header, make sure to have the right tools for the job. The tools needed to replace the headers include a socket wrench, ratchet, a new header gasket, header bolts, and a torque wrench. Other tools needed are a jack stand, a floor jack, and a wrench.

• Lift the car

  After gathering the necessary tools, the next step is to lift the car. A floor jack is used to lift the car, and jack stands are used to hold it in place. This provides enough space to work under the vehicle safely.
