Let's talk about breathing! Upgrading your BRZ's intake and exhaust systems is often the first step for many enthusiasts, and for good reason. These modifications can significantly improve engine airflow, leading to noticeable gains in horsepower and torque. Starting with the intake, a high-flow air filter or a complete cold air intake system can reduce restrictions and allow the engine to draw in more air. This is especially beneficial at higher RPMs, where the engine demands a greater volume of air. When selecting an intake, look for one that is designed to minimize turbulence and maximize airflow. Some intakes also feature heat shields to prevent the engine from drawing in hot air from the engine bay, which can further improve performance. Moving on to the exhaust system, there are several options to consider. A cat-back exhaust system replaces everything from the catalytic converter back, typically including a less restrictive muffler and larger diameter piping. This can significantly reduce backpressure, allowing the engine to exhale more efficiently. For even greater gains, you could consider a full exhaust system, which replaces the catalytic converter with a high-flow unit or removes it altogether (check your local regulations first!). Headers are another key component of the exhaust system. Upgrading to aftermarket headers with optimized runner lengths and smoother bends can further improve exhaust flow and increase horsepower. When choosing exhaust components, pay attention to the materials used. Stainless steel is a popular choice for its durability and corrosion resistance. Titanium exhaust systems are also available, offering even greater weight savings and a unique sound. The sound of your exhaust is also an important consideration. Some exhaust systems are designed to be louder and more aggressive, while others are more subtle. Consider your personal preferences and local noise regulations when making your selection. By carefully selecting and installing intake and exhaust upgrades, you can significantly improve your BRZ's performance and give it a more aggressive sound. Remember to choose components that are compatible with each other and that are designed for your specific model year. With the right combination of intake and exhaust upgrades, you'll be well on your way to unlocking the true potential of your BRZ's engine.

ECU Tuning

Alright, guys, let's dive into the brains of the operation: the ECU, or Engine Control Unit. ECU tuning is a critical aspect of maximizing the performance gains from any modifications you make to your BRZ. The ECU is responsible for controlling various engine parameters, such as fuel injection, ignition timing, and air-fuel ratio. When you install performance upgrades like intakes, exhausts, or headers, the ECU may not be optimized to take full advantage of these modifications. This is where ECU tuning comes in. By remapping the ECU, you can optimize these parameters to match the new hardware, resulting in significant gains in horsepower, torque, and overall drivability. There are several ways to tune your BRZ's ECU. One popular option is to use a handheld tuning device, which allows you to upload pre-made or custom tunes to the ECU. These devices often come with a variety of features, such as data logging and diagnostic capabilities. Another option is to have your ECU tuned by a professional tuner. This typically involves dyno tuning, where the tuner adjusts the ECU parameters in real-time while the car is running on a dynamometer. Dyno tuning can be more precise and can often yield better results than using a pre-made tune. When choosing a tuner, be sure to select one who is experienced with the Subaru BRZ and who has a good reputation. A good tuner will be able to understand your goals for the car and create a tune that is tailored to your specific modifications and driving style. In addition to optimizing performance, ECU tuning can also improve fuel economy and throttle response. By fine-tuning the air-fuel ratio and ignition timing, you can make the engine run more efficiently and reduce fuel consumption. Improved throttle response can make the car feel more responsive and engaging to drive. However, it's important to note that ECU tuning can also have potential risks. If the tune is not done properly, it can damage the engine or other components. It's crucial to choose a reputable tuner and to use high-quality tuning software. By carefully considering your options and choosing a qualified tuner, you can safely and effectively tune your BRZ's ECU and unlock its full potential.

Okay, so you've got the engine breathing better and the ECU dialed in. Now, let's talk about handling! Upgrading your BRZ's suspension is crucial for improving its cornering ability, stability, and overall driving experience. The stock BRZ suspension is decent, but it can be significantly improved with aftermarket components. One of the most common suspension upgrades is to install lowering springs. Lowering springs reduce the ride height, which lowers the center of gravity and improves handling. They also typically have a higher spring rate than the stock springs, which reduces body roll and improves stability. When choosing lowering springs, be sure to select ones that are designed for your specific driving style and goals. Some springs are designed for street use, while others are designed for track use. Coilovers are another popular suspension upgrade. Coilovers are adjustable suspension units that allow you to fine-tune the ride height, damping, and rebound. This gives you a high degree of control over the car's handling characteristics. Coilovers are a great option for those who want to dial in their suspension for specific track conditions or driving styles. Sway bars are another important component of the suspension system. Sway bars connect the left and right wheels and help to reduce body roll during cornering. Upgrading to aftermarket sway bars with a higher stiffness can significantly improve the car's handling. Bushings are often overlooked, but they play a crucial role in the suspension system. Bushings are rubber or polyurethane components that connect the suspension components to the chassis. Over time, the stock bushings can wear out and become soft, which can negatively affect handling. Upgrading to aftermarket bushings with a higher durometer can improve handling and reduce unwanted movement in the suspension system. By carefully selecting and installing suspension upgrades, you can significantly improve your BRZ's handling and make it an even more enjoyable car to drive. Remember to choose components that are compatible with each other and that are designed for your specific needs and driving style.

Forced Induction: Turbocharger or Supercharger

Alright, buckle up, because we're about to get serious! If you're looking for a significant power boost for your BRZ, forced induction is the way to go. This typically means adding a turbocharger or a supercharger. Both of these systems force more air into the engine, allowing it to burn more fuel and produce significantly more horsepower and torque. Turbochargers use exhaust gas to spin a turbine, which in turn compresses the intake air. They are generally more efficient than superchargers, but they can also suffer from turbo lag, which is a delay between when you press the throttle and when the turbocharger starts to produce boost. Superchargers, on the other hand, are driven directly by the engine via a belt. They provide instant boost and a more linear power delivery, but they are typically less efficient than turbochargers. When choosing between a turbocharger and a supercharger, consider your driving style and goals. If you want maximum horsepower and are willing to deal with some turbo lag, a turbocharger may be the better choice. If you prefer a more linear power delivery and instant boost, a supercharger may be a better fit. Installing a turbocharger or supercharger is a complex process that typically requires professional installation. It also requires supporting modifications, such as upgraded fuel injectors, a larger fuel pump, and an intercooler to cool the compressed air. ECU tuning is also essential to ensure that the engine is running safely and efficiently. Forced induction can significantly increase the power output of your BRZ, but it also puts more stress on the engine and other components. It's important to choose a high-quality kit and to have it installed by a qualified technician. With the right setup, you can transform your BRZ into a true performance machine. However, it's crucial to do your research and to plan carefully before diving into forced induction. By carefully considering your options and choosing the right components, you can safely and effectively boost the power of your BRZ and enjoy a thrilling driving experience.
