What You'll Need: Parts and Considerations

Okay, so you're ready to turbocharge your Challenger V6. Let's break down the essential components you'll need:

Turbocharger: The heart of the system. Choosing the right turbo depends on your goals. Do you want a quick spool for street driving, or are you aiming for maximum horsepower at the track? Consider factors like turbo size, A/R ratio, and compressor map. Research is key here. Don't just grab the first shiny turbo you see. Think about how the turbo will perform in different driving situations. A smaller turbo will spool up faster and provide better low-end torque, making it ideal for daily driving. A larger turbo will deliver more horsepower at higher RPMs but may suffer from turbo lag, which can be frustrating on the street. Match the turbo to your driving style and performance goals for the best results. Brands like Garrett, Precision Turbo, and BorgWarner are well-regarded in the turbocharger world.
Intercooler: A must-have. As the turbocharger compresses the air, it heats up. Hot air is less dense and contains less oxygen, which reduces performance. An intercooler cools the compressed air before it enters the engine, resulting in more power. You'll need to decide between an air-to-air or air-to-water intercooler setup. Air-to-air intercoolers are simpler to install and generally more affordable. They mount in front of the radiator and use ambient air to cool the compressed air. Air-to-water intercoolers are more efficient but also more complex and expensive. They use a separate water-cooling system to cool the air. Choose the intercooler that best suits your budget, performance goals, and available space.
Exhaust Manifold/Headers: You'll need a way to connect the turbocharger to your engine's exhaust. Turbo manifolds are designed specifically for this purpose. Aftermarket headers can also improve exhaust flow and further enhance performance. Look for manifolds made from durable materials like stainless steel or cast iron. Consider the design of the manifold as well. A well-designed manifold will promote smooth and efficient exhaust flow, which can improve turbo response and overall performance. Some manifolds are designed with equal-length runners, which ensure that each cylinder has the same exhaust flow, leading to more consistent power delivery. Be sure to choose a manifold that is compatible with your turbocharger and engine.
Fuel Injectors: More air means you'll need more fuel. Upgrading your fuel injectors is crucial to prevent a lean condition, which can damage your engine. Choose injectors with a flow rate that matches your power goals. A lean condition occurs when the engine doesn't receive enough fuel to match the amount of air being ingested. This can lead to overheating, detonation, and ultimately engine failure. To prevent this, you'll need to upgrade your fuel injectors to provide the necessary fuel flow. Choose injectors with a flow rate that is appropriate for your power goals. It's always better to err on the side of too much fuel than not enough. Consult with a tuner or performance shop to determine the correct injector size for your application.
Fuel Pump: To support the upgraded injectors, you'll likely need a higher-flowing fuel pump. This ensures that the fuel system can keep up with the demands of the turbocharger. A fuel pump that can't keep up will result in fuel starvation, which can also damage your engine. Upgrading the fuel pump is a critical step in ensuring the reliability and performance of your turbocharged engine. There are many different fuel pumps available, so choose one that is compatible with your fuel system and can provide the necessary flow rate for your power goals. Again, consult with a tuner or performance shop for guidance.
Engine Management System (EMS): This is where the magic happens. You'll need a way to tune your engine to work with the turbocharger. A standalone EMS or a piggyback system can adjust fuel, timing, and other parameters for optimal performance. The engine management system is the brain of your turbocharged engine. It controls everything from fuel delivery to ignition timing. A standalone EMS replaces the factory ECU and gives you complete control over the engine's parameters. A piggyback system works in conjunction with the factory ECU and allows you to make adjustments to the fuel and timing maps. Choose the EMS that best suits your needs and budget. A standalone EMS offers more flexibility and control but also requires more expertise to tune. A piggyback system is easier to install and tune but may not offer as much flexibility.
Boost Controller: This allows you to control the amount of boost the turbocharger produces. You can choose between a manual or electronic boost controller. A boost controller regulates the amount of pressure that the turbocharger produces. A manual boost controller is a simple device that allows you to adjust the boost pressure manually. An electronic boost controller uses a solenoid valve to control the boost pressure electronically. Electronic boost controllers offer more precise control and can be programmed to adjust the boost pressure based on various parameters, such as throttle position and engine RPM. Choose the boost controller that best suits your needs and preferences.
Gauges: Monitoring your engine's vitals is crucial. Install gauges to keep an eye on boost pressure, air/fuel ratio, and oil pressure. Gauges provide valuable information about the health and performance of your engine. Boost pressure gauges allow you to monitor the amount of pressure that the turbocharger is producing. Air/fuel ratio gauges allow you to monitor the mixture of air and fuel in the engine. Oil pressure gauges allow you to monitor the oil pressure in the engine. Monitoring these parameters can help you identify potential problems before they cause serious damage. Choose gauges that are accurate and easy to read. Install them in a location where you can easily see them while driving.
Blow Off Valve (BOV) or Diverter Valve: This releases excess pressure when you let off the throttle, preventing compressor surge. Compressor surge can damage the turbocharger. A blow-off valve (BOV) releases the excess pressure to the atmosphere, creating a distinctive whooshing sound. A diverter valve recirculates the excess pressure back into the intake system. Choose the valve that best suits your preferences and performance goals. A BOV is generally louder and more noticeable, while a diverter valve is quieter and more discreet.

Installation: DIY or Pro?

This is a big question. Installing a turbocharger is not a beginner's job. It requires mechanical skills, specialized tools, and a good understanding of engine management. Here's a breakdown:

DIY: If you're mechanically inclined, have experience working on cars, and are comfortable with wiring and tuning, you might be able to tackle the installation yourself. However, be prepared for a steep learning curve and potential setbacks. You'll need access to a well-equipped garage, a comprehensive set of tools, and a lot of patience. Research is crucial. Read online forums, watch tutorial videos, and gather as much information as possible before you start. Be prepared to spend a significant amount of time on the project.
Professional Installation: This is the safer and often faster option. A reputable performance shop will have the experience and expertise to install the turbocharger correctly and tune your engine for optimal performance. While it will cost more, you'll have peace of mind knowing that the job is done right. Shop around and get quotes from several different shops before making a decision. Ask about their experience with turbocharging V6 Challengers. Check their online reviews and ask for references. Choose a shop that you trust and that has a proven track record of success.
