We'll cover everything from engine specs to performance, reliability, and even some common issues you might encounter. Buckle up, and let's get started!

Under the Hood: The FA20DIT Engine

The 2016 Subaru Impreza WRX boasts the FA20DIT engine, a 2.0-liter, four-cylinder, horizontally-opposed (boxer) engine with direct injection and a twin-scroll turbocharger. This engine is a significant upgrade from previous generations and is known for its responsive power delivery and overall performance. The direct injection system ensures that fuel is sprayed directly into the cylinders, leading to more efficient combustion and increased power output. The twin-scroll turbocharger helps to reduce turbo lag, providing a more immediate and linear throttle response. This combination of technologies makes the FA20DIT a potent and enjoyable engine to drive.

One of the standout features of the FA20DIT engine is its boxer configuration. Unlike inline or V-shaped engines, the boxer engine has its cylinders arranged horizontally, with pistons moving in opposite directions. This design contributes to a lower center of gravity, which improves the car's handling and stability. The lower center of gravity reduces body roll during cornering, allowing for sharper and more precise handling. Additionally, the boxer engine's balanced design helps to minimize vibrations, resulting in a smoother and more refined driving experience. The FA20DIT engine is not only powerful but also contributes to the overall driving dynamics of the 2016 Subaru Impreza WRX.

Furthermore, the FA20DIT engine is designed with durability in mind. Subaru has implemented several features to ensure the engine can withstand the stresses of high-performance driving. The engine block is made from high-strength aluminum alloy, providing a lightweight yet robust foundation. The crankshaft and connecting rods are forged from high-quality steel, enhancing their strength and resistance to wear. The pistons are designed to withstand high combustion pressures, ensuring reliable performance even under demanding conditions. These design choices reflect Subaru's commitment to building engines that are both powerful and reliable. The FA20DIT engine is a testament to Subaru's engineering expertise and its dedication to providing drivers with a thrilling and dependable driving experience. Whether you're hitting the track or navigating city streets, the FA20DIT engine delivers the performance and reliability you need.
