What is the advantage of a low-compression kit?

A low-compression kit is ideal for builds that plan to use forced induction, such as turbochargers or superchargers. Lower compression ratios allow for higher boost pressures without causing engine knock or detonation, leading to more significant power gains.

What is included in the Step 2 Full Kit?

This kit includes forged pistons, I-beam connecting rods, and a crankshaft. These are the core components of the engine's rotating assembly, allowing for a displacement increase to 2.1L and providing a strong foundation for performance builds.

What else might be needed for this engine build?

For a complete engine build using this kit, you will likely need new gaskets, seals, bearings, and potentially upgraded fuel system components and engine management tuning. Professional installation and tuning are highly recommended.

Product Details

HKS is well-known for creating high-performance parts for Japanese vehicles, and this Step 2 Full Kit for the 2013-2020 Subaru BRZ is a prime example of their dedication to enhancing engine capabilities. This comprehensive kit is designed to take your FA20 engine beyond its stock limitations, offering a robust foundation for significant power increases. It's built for enthusiasts looking to rebuild or significantly upgrade their engine's internal components for improved performance and durability under demanding conditions.

At the heart of this kit are forged pistons, which are considerably stronger and more durable than cast pistons, allowing them to withstand higher cylinder pressures and temperatures. Complementing the pistons are I-beam connecting rods, known for their strength-to-weight ratio, making them ideal for high-RPM operation and increased power output. The kit also includes a crankshaft, the backbone of your engine's rotating assembly, ensuring smooth and reliable power delivery. This combination of components creates a well-balanced and strong rotating assembly, specifically engineered for a 2.1L displacement increase, which contributes to improved torque and overall engine responsiveness.

This Step 2 kit is a substantial upgrade, intended for those who plan to push their BRZ's performance envelope. It is important to note that this kit is not CARB approved and cannot be shipped to California. For optimal results and to ensure the longevity of these high-performance components, professional installation and tuning are highly recommended. This kit represents a significant investment in your vehicle's performance potential, providing the core components needed for a serious engine build.
