But if done correctly, turbocharging can be a rewarding modification that transforms your Civic Si into a high-performance beast.

Key Components for a Turbocharged Civic Si

When turbocharging your 2014 Civic Si, there are several key components you need to consider. The turbocharger itself is the heart of the system, but it's just one piece of the puzzle. To ensure the engine can handle the increased power and remain reliable, you'll need to upgrade other components as well. Let's take a look at some of the most important parts:

• Turbocharger: The turbocharger is responsible for compressing air and forcing it into the engine, increasing its power output. When choosing a turbocharger, consider factors such as size, type (e.g., journal bearing or ball bearing), and boost level. A smaller turbocharger will spool up quickly, providing good low-end torque, while a larger turbocharger will deliver more top-end power. Common brands include Garrett, BorgWarner, and Precision Turbo.
• Intercooler: An intercooler cools the compressed air from the turbocharger before it enters the engine. This helps to increase the air's density, resulting in more power. There are two main types of intercoolers: air-to-air and air-to-water. Air-to-air intercoolers are simpler and more common, while air-to-water intercoolers are more efficient but also more complex.
• Fuel Injectors: The stock fuel injectors may not be able to supply enough fuel to meet the engine's demands when turbocharged. Upgrading to larger fuel injectors ensures that the engine receives an adequate amount of fuel, preventing it from running lean and potentially causing damage. Injector Dynamics and DeatschWerks are popular brands.
• Fuel Pump: Similar to the fuel injectors, the stock fuel pump may not be able to deliver enough fuel to support the increased power. Upgrading to a higher-flowing fuel pump ensures that the engine receives a consistent supply of fuel, even at high RPMs and boost levels. Walbro and AEM are well-known brands.
• Engine Management: The stock ECU (Engine Control Unit) may not be able to properly control the engine with a turbocharger. Upgrading to a standalone engine management system or using a piggyback ECU allows you to fine-tune the engine's parameters, such as fuel delivery, ignition timing, and boost control. Hondata and KTuner are popular choices for Honda engines.
• Boost Controller: A boost controller allows you to adjust the amount of boost the turbocharger produces. This can be done manually with a manual boost controller or electronically with an electronic boost controller. An electronic boost controller offers more precise control and allows you to set different boost levels for different driving conditions.
• Exhaust System: Upgrading to a larger diameter exhaust system can help to reduce backpressure and improve exhaust flow, resulting in more power. A cat-back exhaust system replaces the exhaust system from the catalytic converter back, while a turbo-back exhaust system replaces the entire exhaust system from the turbocharger back.
