Turbochargers? Heck Yeah!

Are you thinking about turbocharging your engine? It's a great idea! Turbocharging your engine is a great way to improve its performance, without going completely overboard. Turbochargers are a great option to improve engine performance, without becoming excessive. Before you go turbocharging your engine, let's take a quick look at the finer details of turbochargers and the best way to go about installing one.

If you're not sure what a Turbocharger is exactly, it's essentially a device that makes use of exhaust gas to turn a motor, which in turn powers the compressor to force more air into the combustion chamber of the engine. The result of this is increased power and torque, and who on Earth doesn't want that?

Turbo Types Galore

The Lone Turbo

No doubt single turbo setups are the most popular type of turbocharger setup. A single turbo setup is exactly what the name suggests; this is when one turbocharger is attached directly to an engine. This type of setup is cost-effective and has a wide range of applications, from small cars to even large trucks.

Double Trouble: Twin Turbos

A twin turbo setup is when two turbochargers are used in the same direction, or in succession. Parallel twin turbos are ideal for engines with larger capacities that require more horsepower. Sequential twin turbos provide superior performance throughout the range of engine RPM.

Diesel and Gasoline Engines: Turbo Time

Both gasoline and diesel engines can benefit from the advantages of turbocharging. Diesel engines, specifically appreciate turbochargers because of the high ratio of compression as well as the high torque output even at low speeds. The engines of gasoline can also benefit from turbocharging, particularly in the case of achieving more power and better efficiency in fuel consumption.

The Benefits of Turbocharging

Turbochargers come with a myriad of benefits like:

  • Increased horsepower and torque
  • Better fuel efficiency – yay!
  • Lower emissions, double yay!
  • Smaller, more efficient engines.
  • Enhanced engine performance – vroom vroom!


The Nitty-Gritty: Turbocharger Components


The compressor's function is to compress intake air by increasing its density and pressure prior to taking it to the combustion chamber of the engine. This will allow for more air to be able to enter, in addition to fuel to burn which will result in increased power.


The turbine is powered by exhaust gases that circulate through. This is what makes it spin. The energy generated by the rotation is then transmitted to the compressor which is linked to the turbine by the shaft.

Exhaust Manifold

The exhaust manifold is responsible for carrying the exhaust gases from the engine into the turbine, which allows the turbocharger to achieve its function.

Turbocharging: Naturally Aspirated Engines

Upgrading a naturally aspirated motor to a turbocharged model could potentially lead to significant performance gains. It's important to note that this requires careful planning and careful consideration of a few key things. For instance; the strength of the engine, as well as the size of the turbocharger. This is crucial to ensuring that the engine is able to withstand the increased power output and potential strains caused by turbocharging.

Turbocharger Sizing and Matching: Size Matters

Picking out the correct size of turbocharger suitable for the engine you're upgrading is vital in achieving maximum performance. Some things that you need to consider when selecting an appropriate turbo are; the power goals, torque, RPM range, as well as the purpose for which it's intended. We recommend that you talk to a knowledgeable mechanic or tuner, such as one of our very own online mechanics, who can properly assist you in finding the ideal turbocharger suitable for your vehicle's engine.

Engine Modifications for Turbocharging: The Support System

When deciding to upgrade to a turbocharged motor, it's essential that you make the necessary modifications prior to the installation to ensure durability and reliability. Some of these important modifications may include:

  • Upgrading parts of the engine (piston rods, pistons.)
  • Stabilizing the engine block.
  • Installing an intercooler to cool intake air that has been compressed.
  • Upgrading the fuel system and injectors.
  • Implementing an appropriate Engine management method.


Boosting Pressure Management

The performance and dependability of turbocharged engines depend greatly on the regulation of boost pressure. The amount of pressure produced by the turbocharger can be regulated with the help of a fitted boost controller. When compared to manual controllers, electronic boost controllers can offer greater precision and versatility, enabling you to modify the engine's performance.

Turbocharger Maintenance: Take Care of Your Turbo

It goes without saying that regular maintenance is important to keep your vehicle in tip-top shape. It is especially important however with turbochargers to ensure that your turbocharged engine is working efficiently. Here are some of the most important maintenance tasks:

  • Changing the oil regularly and using synthetic oil of high quality.
  • Cleaning and checking the air filter on a regular basis.
  • Checking the turbocharger and other parts for wear or damage.
  • Monitoring the engine's performance and boosting pressure to spot any issues early.

Potential issues to look out for

While we have already discussed many of the benefits of turbochargers in this article, they also have the potential to create some problems. Some of these problems could be caused by:

  • More engine heat and stress.
  • Turbos lag occurs in certain settings.
  • Engine failure if the engine is not maintained properly or modified as needed.
