What Is a BRZ Supercharger Kit?

If you love the sharp handling of your Subaru BRZ but find yourself wishing for more power, a supercharger kit is one of the most effective upgrades you can make. Think of it as a comprehensive performance package designed to solve the BRZ’s one major weakness: its modest factory horsepower. These kits bundle together everything you need to force more air into your engine, which is the key to unlocking significant gains in both horsepower and torque.

A typical kit includes the supercharger unit itself—which is essentially a high-speed air compressor—along with all the necessary belts, pulleys, intake piping, and mounting hardware. Some kits also include components for cooling and fuel system upgrades to support the extra power. By installing a supercharger, you’re fundamentally changing how your engine breathes, allowing it to produce the kind of power that makes the car feel truly alive. It’s a popular and well-supported path for transforming your BRZ from a momentum car into a genuine powerhouse, all while maintaining a smooth and reliable driving experience.

How Superchargers Add Power

At its core, an engine creates power by igniting a mixture of air and fuel. To get more power, you need to get more air into the cylinders. A supercharger does exactly that. It’s a belt-driven compressor that’s mechanically linked to your engine’s crankshaft. As the engine spins, it spins the supercharger, which compresses incoming air and forces it into the engine under pressure. This dense, oxygen-rich air allows your engine to burn more fuel with each combustion cycle, resulting in a substantial power increase.

The key advantage of this belt-driven design is its immediacy. Unlike a turbocharger that relies on exhaust gases and can have a slight delay, a supercharger provides instant response the moment you press the throttle. This results in a smooth, linear power delivery with zero lag, making the car feel responsive and powerful across the entire RPM range. This is a key difference when considering a BRZ turbo kit vs supercharger.

Why Supercharge Your BRZ?

The main reason to supercharge your BRZ is to completely transform its performance character. While the BRZ is celebrated for its balance and agility, many drivers feel it’s held back by a lack of straight-line speed. A supercharger kit directly addresses this, often pushing the vehicle’s output well beyond 300 horsepower. This added power turns the BRZ into a much more capable and exciting machine, whether you’re merging onto the highway or hitting the track for a weekend session.

Beyond the raw numbers, supercharging provides a refined power delivery that feels like a factory upgrade. The power comes on smoothly and predictably, enhancing the driving experience without making the car feel unruly or difficult to manage. It’s the ideal solution for enthusiasts who want a significant performance jump while maintaining drivability for daily use.

What Performance Gains Can You Expect?

Installing a supercharger is one of the most transformative upgrades you can make to your Subaru BRZ. The stock BRZ is rightfully celebrated for its incredible handling and balanced chassis, but let's be honest—many of us wish it had more power from the factory. A supercharger kit is the most direct way to fix that. By forcing more air into the engine, it creates a substantial increase in power that you can feel instantly. This isn't just about chasing a higher number on a dyno sheet; it's about fundamentally changing how your car feels and responds every time you press the accelerator. The gains are noticeable across the entire powerband, from raw horsepower and torque figures to the immediate power delivery and crisp throttle response. A well-designed kit delivers this power smoothly, making your BRZ feel like a more potent, factory-tuned machine. When you're ready to give your car the power its chassis deserves, exploring performance parts like a supercharger is the logical next step. It bridges the gap between a great handling car and a true performance vehicle, giving you the best of both worlds for the street or the track.

More Horsepower and Torque

The most dramatic change you'll feel after installing a supercharger is the surge in horsepower and torque. A stock BRZ is fun, but it's not necessarily fast. A supercharger kit changes that equation entirely. For example, some popular kits on the market can add over 85 horsepower and 70 ft-lbs of torque at the wheels. Other systems claim to increase your engine's horsepower by as much as 50% over stock. This kind of increase completely transforms the car's character, providing strong acceleration out of corners and effortless power on the highway. It’s the kind of performance that makes the BRZ a true threat on the street or track.

A Look at Power Delivery

One of the biggest advantages of a supercharger is its linear and instant power delivery. Because the supercharger is driven by a belt connected directly to the engine's crankshaft, it provides boost as soon as you hit the gas. This means there's no waiting for power to build. This is a key difference when you compare a BRZ turbo kit vs supercharger, as turbochargers can sometimes have a slight delay, known as "turbo lag." With a supercharger, the power is always on tap, giving you a consistent and predictable pull all the way to redline. This makes the car feel more responsive and connected to your inputs.

Sharper Throttle Response

That instant power delivery translates directly to a much sharper throttle response. Your BRZ will react the moment your foot touches the pedal, making the driving experience more engaging and intuitive. High-quality supercharger kits are carefully engineered to deliver this power smoothly, so the car remains easy to drive and feels like a factory-tuned vehicle, just with a lot more muscle. Whether you're navigating tight turns on a track or just enjoying a spirited drive on a back road, that immediate response gives you greater control and confidence behind the wheel. It’s a refined power that enhances the car’s natural strengths.

How to Compare BRZ Supercharger Kits

For example, some kits are engineered to deliver a 50% horsepower increase over stock, which is a massive jump for daily driving and spirited runs. Others are capable of pushing your BRZ past 400 wheel horsepower, putting you squarely in track-ready territory. Think about your end goal: are you looking for a significant, reliable boost for the street, or are you chasing maximum power for competition? Defining this will help you narrow down your options and find the right performance parts for your build.

Emissions and CARB Certification

Before you get carried away with horsepower figures, let's talk about legality. If you live in California or another state with strict emissions standards, this is a non-negotiable point. A CARB-compliant kit has been tested and approved by the California Air Resources Board, meaning it won't get you in trouble during your next smog check. Many reputable manufacturers design their systems to be 50-state legal, giving you peace of mind. Always check for a CARB Executive Order (EO) number before purchasing. It ensures your performance gains don't come with legal headaches down the road.

Installation Difficulty

How much time do you want to spend in the garage? Supercharger kits range from straightforward 'bolt-on' systems to more complex installations requiring permanent modifications. A true bolt-on kit is designed for a seamless fit without any cutting or drilling. This not only saves you time and potential frustration but also preserves your car's integrity. If you're planning a DIY install, a well-designed kit with clear instructions is your best friend. For more complex setups, factoring in the cost of professional engine tuning services is a must to ensure everything runs perfectly.

Cooling and Heat Management

Adding a supercharger means adding heat—a lot of it. Your engine's ability to manage that heat is critical for both performance and longevity. A quality kit will always include a robust cooling solution, such as an intercooler or a front-mount heat exchanger. These components cool the compressed air before it enters your engine, resulting in denser air, more power, and a lower risk of detonation. Skimping on cooling is a recipe for disaster, especially if you plan on pushing your BRZ hard. An efficient cooling system is the foundation of a reliable, high-performance build.

Understanding Supercharger Costs

A supercharger is a serious investment in your BRZ's performance, and the final price tag involves more than just the kit itself. When you start budgeting, it's helpful to think about the total cost of the project, which includes the hardware, installation, and any necessary supporting modifications. Prices can vary significantly based on the brand, the components included, and whether you opt for a professional installation. Getting a clear picture of these expenses from the start will help you make an informed decision and avoid any surprises down the road.

Think of it less as a simple purchase and more as a complete project. The initial kit price is the starting point, but the real value comes from a well-executed installation and tune that delivers reliable power. Some kits are more comprehensive than others, while some may require you to source additional performance parts to complete the setup. Furthermore, the cost of labor for a professional install can be a significant part of the budget, but it often includes the critical step of tuning your engine for its new setup. We'll break down these key financial aspects to give you a realistic understanding of what it takes to supercharge your BRZ the right way.

Kit Pricing by Brand

The price of a supercharger kit can range from around $5,000 to over $7,000, depending heavily on the manufacturer and what’s included. For example, a Jackson Racing C38 Supercharger System typically falls in the $5,200 to $6,200 range.

What's Included in the Box?

When comparing prices, it’s crucial to look at the parts list to understand what you’re actually getting. A more expensive kit might be a better value if it’s more complete. For instance, the Harrop TVS1320 kit is known for being comprehensive, including the supercharger, a cooling system, and all the necessary hardware for installation. Other kits, like the Jackson Racing system, offer a "Factory Tuned" option that comes with a pre-loaded ECU calibration. Always check if a kit includes essentials like an intercooler, fuel injectors, and a tuning solution, as purchasing these separately will add to your total cost.

Professional vs. DIY Installation Costs

While a DIY installation can save you money on labor, it’s a complex job that requires the right tools and expertise. For a modification this significant, professional installation is almost always the better path. A reputable shop not only ensures everything is fitted correctly but also provides a custom engine tune tailored to your specific vehicle. This tune is essential for protecting your engine and getting reliable, optimized performance. Labor costs vary by location and shop, so get a few quotes. Factoring in a professional install and tune from the beginning is the smartest way to safeguard your investment.

The Truth About Installation

Installing a supercharger is a significant upgrade, and it’s natural to have questions about what the process involves. While it might seem like a job reserved for professional mechanics, many kits are designed for a competent home mechanic to handle. The key is to be prepared, patient, and realistic about the scope of the work. With the right approach and a clear set of instructions, you can successfully complete the installation and get your BRZ back on the road with a serious power upgrade.

Required Tools and Equipment

One of the best things about modern supercharger kits is that most are designed to be direct bolt-on modifications. This means they are engineered to work with your stock intake and ECU, minimizing the need for custom fabrication. The installation primarily involves using standard hand tools like a good socket set, wrenches, and screwdrivers. You won’t need a full professional shop, but a clean workspace, a jack, and jack stands are essential for safety and access. Always follow the manufacturer's instructions precisely, as they provide the step-by-step guide for your specific kit.

Common Installation Myths

Let’s clear up a few misconceptions. A common myth is that supercharger kits are significantly more complex to install than their turbo counterparts. In many cases, the opposite is true. Supercharger installations often involve less intricate work with exhaust manifolds and plumbing, making them more straightforward. Another point of concern is belt failure. While it's true that the supercharger is belt-driven and these belts can wear out, this is a standard maintenance item, not a sudden catastrophic failure. With proper tensioning during installation and regular inspections, you can easily manage belt health.

Necessary Supporting Mods

For most bolt-on kits running conservative boost levels on a daily driver, your stock BRZ engine is perfectly capable of handling the extra power. However, if your goal is to push for higher boost and maximum horsepower, you’ll need to invest in supporting modifications. To ensure reliability under serious power, you should consider upgrading internal engine components like pistons and connecting rods. Before you even get to that point, a robust fuel system and a proper ECU tune are absolutely essential. Professional engine tuning services will ensure your engine runs safely and efficiently with its new setup.

Legal and Emissions Concerns

Adding a supercharger is one of the most exciting upgrades you can make to your BRZ, but it’s important to think beyond the dyno sheet. Before you commit to a kit, you need to understand the legal and warranty implications. Ensuring your build is compliant with state laws and knowing how it might affect your factory warranty will save you from major headaches down the road. Let's walk through what you need to know to keep your supercharged BRZ both powerful and problem-free.

Staying 50-State Compliant

When you're shopping for a supercharger, you'll often see the term "50-state compliant" or "CARB-legal." This means the kit has been tested and proven not to exceed federal and state emissions standards, making it legal to install and drive anywhere in the US, including states with the strictest regulations. Choosing a compliant kit is the best way to enjoy your car's new power without worrying about failing an emissions test or facing legal penalties. Many manufacturers invest heavily in engineering their performance parts to meet these requirements, so you don't have to sacrifice performance for peace of mind. It's a critical detail to check before making a purchase.

The Importance of CARB Certification

The California Air Resources Board, or CARB, sets some of the most stringent air quality standards in the world. For an aftermarket part to be sold and used on a vehicle in California, it must receive a CARB Executive Order (EO) number. This certification is a big deal because it proves the part has undergone rigorous testing and won't negatively impact the vehicle's emissions output. Even if you don't live in California, a CARB-certified kit is a benchmark for quality and responsible engineering. It tells you the manufacturer has done their due diligence to create a product that integrates cleanly with your BRZ's factory systems.

How It Affects Your Warranty

This is the big question for many owners: will a supercharger void my warranty? The short answer is, it's complicated. Legally, under the Magnuson-Moss Warranty Act, a dealer can't void your entire vehicle warranty just for installing an aftermarket part. They must prove that the supercharger directly caused the specific failure you're claiming. However, if your engine or drivetrain experiences an issue after installation, you may face an uphill battle with the dealership. Some kits are designed to work seamlessly with factory components, which can help, but it's crucial to review your warranty agreement and understand the risks. Discussing your plans with a reputable performance shop can also provide clarity.

Choosing the Right Kit for Your Build

The "best" supercharger kit is the one that aligns perfectly with how you use your BRZ. A setup designed for maximum track performance might feel too aggressive for a daily commute, while a budget-friendly option may not have the power potential a serious racer needs. Think about your primary goal for the car—whether it's navigating city streets, setting new personal bests at the track, or simply getting the most bang for your buck. This will guide you to the right hardware for your build and ensure you’re happy with the result for years to come. Let's break down the top considerations for each type of driver.

For the Daily Driver

If your BRZ is your primary mode of transportation, your main priorities should be reliability and smooth power delivery. You want a supercharger that integrates seamlessly, providing a linear power curve that feels like a factory upgrade, not a jarring aftermarket add-on. The Jackson Racing system is a popular choice for this reason. It’s engineered to give you a significant performance increase without sacrificing the refined drivability you need for stop-and-go traffic and highway cruising. A proper engine tune is critical here to ensure the car remains dependable and easy to handle every day.

For the Track Star

On the track, instant response and high-end power are everything. You need a supercharger that delivers a massive punch the moment you touch the throttle, helping you power out of corners and shorten straightaways. The Harrop TVS1320 kit is built specifically for this purpose, engineered to maximize the FA20 engine’s output for competitive driving. Its immediate power delivery is a key advantage over turbochargers, which can have a slight delay. For track builds, pairing the kit with professional engine tuning services is non-negotiable to extract every bit of safe, reliable power and dial in the car for consistent lap times.

For the Budget-Conscious Builder

When you're building on a budget, it’s crucial to look beyond the sticker price of the supercharger kit itself. While a system like the Jackson Racing kit runs between $5,000 and $6,000, a smart builder budgets for the total project cost. A good rule of thumb is to plan on spending roughly double the price of the kit. This extra amount covers essential expenses like professional installation, a custom tune, and necessary supporting performance parts like an upgraded fuel pump or clutch. Factoring in these costs from the start prevents surprises and ensures you can complete the build correctly without cutting corners.

Must-Have Mods for Your Supercharged BRZ

Installing a supercharger is a huge step toward unlocking your BRZ’s potential, but the kit itself is only part of the equation. To handle the significant increase in power safely and reliably, you need to invest in supporting modifications. Think of it like building a house—you wouldn't put a second story on a foundation designed for a single-level home. The same principle applies here. Your stock components were engineered for factory horsepower levels, and pushing them far beyond that limit without reinforcement is a recipe for failure. These parts aren't just nice-to-haves; they are essential for protecting your investment and ensuring your newly supercharged engine runs smoothly for years to come.

From delivering adequate fuel to managing extra heat, each upgrade plays a critical role in creating a balanced and durable performance build. Neglecting these areas can lead to catastrophic engine damage, leaving you with a much bigger bill than the cost of the mods themselves. It's easy to get excited about the big power numbers a supercharger promises, but the real secret to a successful build lies in the details. By addressing the fuel system, engine management, cooling, and drivetrain, you create a robust platform that can maximize the benefits of forced induction and give you peace of mind on the street or the track.

Upgrading Your Fuel System

Once your supercharger is forcing more air into the engine, you need to supply a lot more fuel to match. The stock fuel pump and injectors simply can't keep up with the demand, which can cause your engine to run lean—a dangerous condition where there's too much air and not enough fuel. This can lead to detonation, or engine knock, which can destroy your pistons and other internal components. To prevent this, you absolutely need to upgrade your fuel system. A high-flow fuel pump and larger injectors are crucial for delivering the right amount of fuel to handle the extra power safely and consistently.

Tuning Your Engine Management

A supercharger completely changes how your engine breathes, and the factory Engine Control Unit (ECU) isn't programmed to manage it. This is where a custom tune comes in. A professional tune is vital for the safety, reliability, and performance of your new setup. An expert tuner will recalibrate your ECU’s maps for the new air and fuel flow, optimizing ignition timing and air-fuel ratios for forced induction. Skipping this step is one of the worst mistakes you can make, as it can severely damage your engine. Proper engine tuning services ensure your BRZ runs not just powerfully, but safely.

Enhancing Your Cooling System

Forced induction generates a substantial amount of extra heat, and the stock cooling system can quickly become overwhelmed. Managing this heat with cooling upgrades is incredibly important for engine longevity and consistent performance. An oil cooler is one of the most effective mods, as it helps keep your oil temperatures stable, protecting your engine's internal components from premature wear. For track use or aggressive driving, an upgraded radiator is also a smart investment. These performance parts work together to prevent overheating, ensuring you can enjoy that extra power without worrying about thermal issues.

Strengthening Your Drivetrain

Your BRZ’s stock clutch was designed to handle factory torque levels, and not much more. The instant torque delivery from a supercharger will cause the stock clutch to slip and wear out very quickly. It’s simply not strong enough for the added power and will almost certainly fail, leaving you unable to transfer that newfound power to the wheels. An upgraded performance clutch is a must-have modification. It provides the necessary clamping force to handle the increased torque, ensuring reliable engagement and long-term durability so you can confidently put the power down without hesitation.

Long-Term Care for a Supercharged BRZ

Adding a supercharger is a serious commitment that goes beyond the installation day. To keep your BRZ running strong and reliably, you'll need to adjust your approach to maintenance. Think of it this way: you’ve asked your engine to do more work, so it needs more support to perform its best over the long haul. This doesn’t mean your car will be fragile, but it does mean you can’t stick to the factory service schedule anymore.

Proper long-term care is what separates a thrilling, dependable build from one that causes constant headaches. By staying on top of fluid changes, inspections, and using the right components, you ensure the investment you made in performance continues to pay off every time you get behind the wheel. A proactive mindset is key. Instead of waiting for something to go wrong, you’ll be taking steps to prevent issues before they start, which is the smartest way to own any modified vehicle.

What to Expect for Maintenance

A supercharger adds a new layer of complexity to your engine bay. You now have more belts, pulleys, and cooling components that need regular attention. While it might sound intimidating, the maintenance routine is straightforward. You’ll want to regularly inspect the supercharger drive belt for any signs of fraying or cracking, as this is a common wear item. You should also keep an eye on the intercooler and its connections to ensure there are no leaks. Using high-quality performance parts from the start will give you a more durable foundation, but routine checks are still essential for keeping everything in top shape.

Service Intervals and Reliability

Reliability isn't guaranteed after installing a supercharger; it's built through diligent care. The single most important factor, after the initial install, is a professional tune. A proper engine tuning service ensures your air-fuel ratios and timing are perfect for the added boost, protecting your engine from damage. You’ll also need to shorten your service intervals. Plan on changing your oil every 3,000 miles with a high-quality full synthetic oil. It’s also a good idea to check your spark plugs and other fluids more frequently than the owner’s manual suggests. This consistent attention is what allows your supercharged BRZ to deliver reliable power day after day.

Common Maintenance Myths

One of the biggest myths is that supercharger kits are "set it and forget it." In reality, they are dynamic systems that experience wear and tear. As mentioned, supercharger belts can and do fail over time, so treating them as a regular maintenance item is crucial. Another misconception is that you need a loud, custom exhaust to go with your supercharger. Many kits are designed to work perfectly well with the factory exhaust system, which is great for owners who want to maintain a lower profile without sacrificing performance. Understanding these realities helps you stay ahead of maintenance and enjoy your build without any unwelcome surprises.
