Key Components of the PRL Turbo Kit

Understanding what's included in the PRL turbo kit will give you a better appreciation for its value and the engineering that goes into it. Here's a breakdown of some of the key components:

• Turbocharger: The heart of the kit is, of course, the turbocharger itself. PRL typically uses turbochargers from reputable brands like Garrett or Precision. The specific model will vary depending on the power goals and desired spool characteristics. These turbos are chosen for their reliability, efficiency, and ability to deliver the desired boost levels for the K24Z7 engine.
• Exhaust Manifold: The exhaust manifold is responsible for routing exhaust gases from the engine to the turbocharger. PRL typically uses a stainless steel manifold designed for optimal flow and minimal backpressure. This ensures that the turbocharger can spool up quickly and efficiently.
• Downpipe: The downpipe connects the turbocharger outlet to the exhaust system. PRL downpipes are also typically made from stainless steel and are designed to provide a smooth, unrestricted flow of exhaust gases. This helps to reduce backpressure and improve overall engine performance. A high-flow catalytic converter may also be included or offered as an option.
• Intercooler: The intercooler is responsible for cooling the compressed air from the turbocharger before it enters the engine. Cooler air is denser and contains more oxygen, which leads to more power. PRL intercoolers are designed to be highly efficient at cooling the charge air, minimizing the risk of heat soak and maximizing performance.
• Charge Piping: The charge piping connects the turbocharger to the intercooler and the intercooler to the throttle body. PRL charge piping is typically made from aluminum and is designed to be lightweight and durable. The piping is also designed to minimize pressure drop and ensure a smooth flow of air to the engine.
• Fuel Injectors: To support the increased airflow from the turbocharger, larger fuel injectors are required. PRL kits typically include a set of high-flow fuel injectors that can deliver the necessary amount of fuel to the engine. This ensures that the engine doesn't run lean, which can cause serious damage.
• Engine Management/Tuning Solution: A standalone ECU or Accessport with custom tuning is essential. The kit requires professional tuning to optimize air/fuel ratios, ignition timing, and boost control. This ensures safe and reliable operation of the turbocharger system while maximizing power output. Consider Hondata or KTuner for tuning options.

Installation: What to Expect

Installing a turbo kit is a complex process that requires mechanical knowledge and experience. While it's possible to do it yourself, it's generally recommended to have it installed by a qualified mechanic. Here's a general overview of what to expect during the installation process:

1. Preparation: Before you start, make sure you have all the necessary tools and equipment. This includes a jack, jack stands, wrenches, sockets, screwdrivers, and potentially specialized tools like a torque wrench and an oxygen sensor socket. Also, carefully read the installation instructions provided by PRL Motorsports.
2. Removal of Stock Components: The first step is to remove the stock exhaust manifold, downpipe, and potentially other components that will be replaced by the turbo kit. This may involve disconnecting sensors, removing bolts, and carefully maneuvering the parts out of the engine bay.
3. Installation of Turbo Kit Components: Next, you'll begin installing the new components, starting with the exhaust manifold and turbocharger. Make sure to follow the instructions carefully and torque all bolts to the specified values. Pay close attention to the routing of the oil and coolant lines for the turbocharger.
4. Intercooler and Charge Piping Installation: Install the intercooler and charge piping, ensuring that all connections are secure and leak-free. This may involve trimming hoses and adjusting the piping for optimal fitment.
5. Fuel Injector Installation: Replace the stock fuel injectors with the new, high-flow injectors provided in the kit. Be careful when handling fuel injectors, as they are delicate components.
6. ECU Tuning: Once the hardware is installed, you'll need to have the ECU tuned to optimize the engine for the turbocharger. This is typically done by a professional tuner using a standalone ECU or a piggyback tuning solution. The tuner will adjust parameters such as air/fuel ratio, ignition timing, and boost control to ensure safe and reliable operation.
7. Testing and Refinement: After the tuning is complete, it's important to test the car thoroughly to ensure that everything is working properly. Monitor the engine parameters closely and make any necessary adjustments to the tune. It's also a good idea to get the car dyno-tuned to optimize the power output.

Important Considerations:

• Oil and Coolant Lines: Proper installation of oil and coolant lines is crucial for turbocharger lubrication and cooling. Ensure no kinks or leaks are present.
• Boost Control: Setting up the boost controller correctly is vital to prevent overboost, which can damage the engine.
• Professional Tuning: We cannot stress this enough; professional tuning is mandatory for safe and optimal performance.

Performance Gains: What to Expect From Your PRL Turbo Kit

Okay, let's get to the good stuff: the power gains! With the PRL turbo kit installed and properly tuned, you can expect to see a significant increase in both horsepower and torque on your 9th gen Civic Si. The exact numbers will vary depending on the specific turbocharger used, the boost level, and the quality of the tune, but here's a general idea:

• Horsepower: Expect gains in the range of 80-150+ horsepower over stock, depending on the boost level and supporting modifications. Many users report reaching 300+ whp with the PRL kit and proper tuning.
• Torque: The torque gains are even more impressive, especially in the low-end and mid-range. You'll feel a much stronger pull when accelerating from a stop or passing on the highway. Expect torque gains in the range of 70-120+ lb-ft over stock.

The driving experience will be dramatically transformed. The car will feel much more responsive and powerful, with a noticeable increase in acceleration. The turbocharger will provide a boost of power that you can feel in your seat, making driving much more exciting and engaging. However, it's important to remember that with great power comes great responsibility. Be sure to drive responsibly and be aware of the increased power output of your car.

Potential Drawbacks and Considerations

While the PRL turbo kit offers significant performance benefits, it's important to be aware of the potential drawbacks and considerations before making a purchase:

• Cost: Turbo kits are a significant investment, and the PRL kit is no exception. The cost of the kit itself, plus the cost of installation and tuning, can add up quickly.
• Installation Complexity: Installing a turbo kit is a complex process that requires mechanical knowledge and experience. If you're not comfortable working on cars, it's best to have it installed by a professional mechanic.
• Reliability: Adding a turbocharger to an engine can put additional stress on the components, which can potentially reduce reliability. It's important to maintain the car properly and address any issues promptly to minimize the risk of problems.
• Tuning: Proper tuning is essential for safe and reliable operation of the turbocharger system. A poor tune can lead to engine damage.
• Emissions: Adding a turbocharger may affect the car's emissions, potentially making it difficult to pass emissions tests in some areas.
