Understanding the Fundamentals of Turbo Kits
Before diving into the specifics, it’s essential to grasp the basic principles of turbocharging. A turbo kit is essentially a system designed to force more air into the engine’s cylinders. More air allows for more fuel to be burned, resulting in increased power output.
The core component is the turbocharger itself. This device uses the engine’s exhaust gases to spin a turbine wheel. This turbine wheel is connected to a compressor wheel, which then compresses the incoming fresh air and forces it into the engine.
A complete 2013 Subaru BRZ turbo kit typically includes several key components beyond the turbocharger:
- The Turbocharger: The heart of the system, responsible for compressing air. Selecting the right turbocharger is crucial.
- The Exhaust Manifold (Header): This component collects exhaust gases from the engine and directs them into the turbocharger.
- The Wastegate: This device controls the boost pressure by bypassing some of the exhaust gases around the turbine wheel.
- The Blow-Off Valve (BOV) or Diverter Valve (DV): These valves release excess pressure when the throttle is closed, preventing damage to the turbocharger.
- The Intercooler: This cools the compressed air before it enters the engine, increasing its density and further enhancing power.
- Piping and Fittings: These connect all the components together, ensuring proper airflow.
- Fuel Injectors and Fuel Pump: Upgraded fuel injectors and a fuel pump are typically needed to supply the increased fuel demands of a turbocharged engine.
- ECU Tuning: The Engine Control Unit (ECU) must be recalibrated to optimize fuel and ignition timing for the turbocharged engine.
Considering the Options: Choosing the Right Kit
The market offers a variety of 2013 Subaru BRZ turbo kits, each with its own strengths and weaknesses. Choosing the right kit depends on your individual goals, budget, and experience level.
- Bolt-on Kits: These kits are designed for ease of installation and typically include all the necessary components. They often offer a good balance of performance and reliability, making them a popular choice for beginners.
- Tuned Kits vs. Custom Kits: Tuned kits are specifically designed for the BRZ and come with pre-programmed tuning software, making installation and tuning easier. Custom kits are designed and built to order, often offering more customization and higher performance potential, but they require more specialized knowledge and often a custom tune.
Before buying a 2013 Subaru BRZ turbo kit, establish your performance targets. Decide how much horsepower and torque you want to achieve. This will help narrow down your options. Are you aiming for a mild power increase for daily driving, or do you crave maximum horsepower for track days?
Consider the cost of the kit itself, along with any additional parts, installation labor (if not doing it yourself), and tuning.
Consider your mechanical experience. If you are comfortable working on cars, you can likely handle a bolt-on kit. However, custom kits or more complex installations might be best left to professionals.
Component Deep Dive: Key Elements of Your Turbo Upgrade
Selecting the right components is vital. The quality of these parts will significantly impact the performance and reliability of your turbocharged BRZ.
Turbocharger Selection
This is the most crucial decision. Turbocharger size determines the boost range and overall power potential. A smaller turbocharger will offer quicker spool-up and better low-end responsiveness, but might have a lower top-end power ceiling. A larger turbocharger will provide greater peak power, but may experience more turbo lag (the delay between pressing the accelerator and the turbocharger reaching full boost). Consider brands like Garrett, BorgWarner, and Precision Turbo for a balance of performance and reliability.
The Manifold (Header) Choice
Choose a high-quality manifold, often constructed from stainless steel, for durability and optimized exhaust flow. The design should ensure consistent exhaust gas delivery to the turbocharger.
The Wastegate: Regulating Boost
An external wastegate is preferred for precise boost control and the ability to accommodate higher boost levels.
Blow-Off Valve/Diverter Valve
These crucial components prevent compressor surge and extend the life of your turbocharger. A blow-off valve vents excess pressure to the atmosphere, while a diverter valve recirculates the excess pressure back into the intake.
The Importance of an Intercooler
An intercooler is essential for cooling the compressed air. Air-to-air intercoolers are the most common type for street applications, while liquid-to-air intercoolers provide even greater cooling efficiency, especially in extreme conditions.
Fuel System Upgrades are Needed
Adding more air also demands more fuel. Upgraded fuel injectors and a higher-flowing fuel pump ensure that the engine receives the fuel it needs to run safely and efficiently.
ECU Tuning: The Brains of the Operation
Proper ECU tuning is paramount for both performance and engine longevity. The ECU needs to be recalibrated to adjust fuel delivery, ignition timing, and boost pressure to match the new turbo kit. This is where the expertise of a professional tuner is invaluable.
