E120 turbocharger

Types of e120 turbochargers

If one is looking to upgrade their car's engine, the E120 turbocharger is a great choice. It is made by a well-known company called Eagle Power. This turbocharger can make a car's engine much stronger and more powerful. That is because it uses air from the outside to help burn more fuel in the engine. When more fuel and air burn together, the engine can create more power. This E120 turbocharger can help the car go faster and improve its performance.

The E120 turbocharger comes in different types. They include:

• Gas turbine engines: In this type of turbocharger, a gas turbine drives the compressor and is powered by the heat of the exhaust gases. Since the exhaust gases are hotter in this type of turbine, the work output from the gas is greater.
• Axial vs. centrifugal turbocharger: Centrifugal compressors are used instead of axial-flow compressors in this type of turbocharger. As a result, the air is compressed radially rather than axially, leading to more efficient compression.
• Single vs. twin turbochargers: Single turbochargers are the most common type of turbocharger and are used in many vehicles. They are called "single" because only one turbocharger is used with the exhaust system. In contrast, twin turbochargers use two turbochargers in the exhaust system. The two turbochargers can be configured in either a parallel or dual sequential arrangement.

Specifications and Maintenance of E120 Turbocharger

Specifications of E120 Turbocharger

• Engine Displacement:

  The E120 turbocharger has a high-flow design that is ideal for engines between 1.2 L to 1.5 L.

• Compressor Wheel Diameter:

  The E120 compressor wheel diameter is 48 mm. It is responsible for drawing in air and compressing it before sending it into the engine.

• Turbine Wheel Diameter:

  The turbine wheel diameter is 42 mm. This is the component that is spun by the exhaust gases and drives the compressor wheel.

• Aspect Ratio:

  The aspect ratio of the E120 turbo is 1.5. This affects the efficiency and performance characteristics of the turbocharger.

• Trim:

  The trim of the compressor and turbine wheels is rated at 60. This value indicates the shape and size of the blades, which impacts airflow and boost levels.

• Boost Pressure:

  The E120 turbocharger is designed to generate boost pressures of 0.5 to 0.8 bar (7 to 12 psi). This added pressure forces more air into the combustion chamber, leading to increased engine power output.

• Materials:

  The turbine housing, turbine wheel, and other components of the E120 turbo are made from cast iron. Meanwhile, the compressor housing and wheel are constructed using aluminum. These materials were chosen for their heat resistance, strength, and lightweight properties.

• Cooling:

  The E120 turbo uses engine coolant to help regulate and dissipate heat. This is important for maintaining optimal operating temperatures.

Maintenance of E120 Turbocharger

Proper maintenance is crucial for ensuring that the E120 turbocharger continues to function optimally over time. Here are some tips and guidelines for maintaining the E120 turbocharger:

• Regular Oil Changes:

  The E120 turbo relies on clean engine oil for lubrication. Be sure to change the oil as recommended in the owner's manual to prevent damage.

• Use Quality Engine Oil:

  Choose a high-quality engine oil that meets the specifications in the owner's manual. This will help the turbocharger run smoothly and last longer.

• Inspect Oil Lines:

  Regularly check the oil lines going to and from the turbo for any leaks or cracks. These lines are important for getting proper oil to the moving parts of the turbo.

• Allow Cool Down:

  After driving, do not immediately turn off the engine. Let it run for a few minutes to cool the turbo. This prevents overheating and damage over time.

• Check for Boost Leaks:

  Inspect the hoses and connections for the boost system. Look for any cracks, loose fittings, or tears that could cause a boost leak. A leak will make the turbo less effective and hurt engine performance.

• Keep Air Filter Clean:

  Replace the air filter as needed or every 30,000 miles. A dirty filter restricts airflow to the turbo and can reduce power.

• Check Wastegate Operation:

  Manually test the wastegate valve to ensure it opens and closes properly. If it gets stuck, it can cause problems with boost levels.

• Monitor Boost Pressure:

  Use a gauge to keep an eye on the boost pressure coming from the turbo. If the reading is too high or too low, there could be an issue with the turbo itself or another component like the wastegate.

• Visual Inspections:

  Regularly inspect the turbocharger and its components for any signs of wear, damage, or leaks. Look at things like the turbo housing, pipes, and valves.

How to choose E120 turbocharger

Choosing the right E120 turbocharger can be a daunting task, but it doesn't have to be. There are a number of factors that affect the decision-making process. Here are some of them:

• Engine Size and Type

  The size and type of the engine determine the amount of air needed for combustion. Larger engines generate more power and require larger compressors to meet their air requirements. The engine type is also important because gasoline and diesel engines have different power generation methods.

• Power Goals

  Deciding on the power goals is essential when selecting a turbocharger. Higher power targets require larger turbochargers to provide the needed airflow and boost. Consider how the vehicle will be used, such as daily driving, towing, or track performance, to determine the power goals.

• Compressor and Turbine Size

  Comparator and turbine sizes influence the turbocharger's performance characteristics. A larger compressor can generate more boost but may cause turbo lag, while a smaller compressor offers quicker spool time but limited airflow. Find the right balance between size and vehicle power requirements.

• Boost Pressure

  Boost pressure is the force of the compressor that pushes air into the engine's cylinders. It is measured in pounds per square inch (PSI). Selecting a turbocharger that can provide the desired boost pressure is important for achieving the targeted power output. Higher boost levels can lead to engine knock and require proper tuning and supporting modifications.

• Spool Time and Turbo Lag

  Turbo lag is the delay in throttle response due to the time taken by the turbocharger to build boost. Spool time is influenced by the turbocharger size, turbine design, and exhaust system. Smaller turbochargers offer quick spool time but may limit top-end power, while larger ones provide high-end power at the expense of turbo lag.

• Quality and Reliability

  Quality and reliability are important when choosing a turbocharger. Ensure it is sourced from reputable manufacturers to get quality components. Reliable turbochargers offer consistent performance and durability, reducing the need for frequent replacements.

• Supporting Modifications

  The chosen turbocharger must be compatible with the vehicle's existing engine and exhaust system. Consider any supporting modifications, such as upgraded intercoolers, fuel injectors, and exhaust systems, to ensure proper integration and maximize performance. These modifications will help to handle the increased airflow and boost from the turbocharger.

How to DIY and Replace e120 turbocharger

Replacing a turbo can be a daunting task, but with the right tools and mechanical knowledge, it can be done. The tools needed for this job are basic. One will need a socket set, wrenches, and possibly some screwdrivers. It might also be a good idea to have a repair manual for the specific car make and model one is working on. This will provide the necessary steps and torque specs for reassembly.

• 1. Remove the old turbo: Start by disconnecting the battery. Then, drain the oil and coolant. The oil and coolant are what keep the turbo lubricated and the cool. Next, the intake and exhaust pipes should be disconnected, along with the wastegate actuator and oil lines. Finally, the turbo will be unbolted from the exhaust manifold.
• 2. Prepare the new turbo: Before installing the new turbo, it should be primed with oil. This will help it last longer. Once it is primed, the manifold should be gasketed and the downpipe flanged.
• 3. Install the new turbo: Bolt the new e120 turbocharger onto the manifold and connect the exhaust. Then, attach the oil lines, wastegate actuator, and coolant lines. The cooled air from the intercooler should be piped into the engine bay. Finally, reconnect the battery.

It is important to ensure that everything is tightened properly to avoid leaks. One should also make sure to follow the steps in the repair manual for the specific vehicle. If unsure about anything, it is always best to consult with a professional mechanic.
