Brian Crower Subaru EJ257 STI Stroker Kit 83mm Billet Crank I-Beam Extreme Rods 5.141in Cust Pistons

If you're looking to significantly increase the displacement and power potential of your Subaru EJ257 engine, a stroker kit is the way to go. This Brian Crower kit is built for serious performance builds, taking your STI's engine from its stock 2.5 liters up to 2.7 liters. This added displacement means more air and fuel can be burned, leading to a substantial increase in torque and horsepower, especially when paired with supporting modifications.

At the heart of this kit is an 83mm billet crankshaft, precision-machined from a solid piece of steel for maximum strength and durability. This crank is designed to handle the stresses of high-performance engines. Complementing the crank are Brian Crower's I-Beam Extreme connecting rods. These rods are well-built and feature an I-beam design, which offers a strong strength-to-weight ratio, making them ideal for demanding applications. They are paired with custom pistons, tailored to work with the increased stroke and bore size, ensuring optimal compression and combustion efficiency. The kit includes everything you need to get your engine rebuilt with increased displacement: the crankshaft, connecting rods, and custom pistons. This is a comprehensive package for anyone serious about extracting more performance from their EJ257 engine.

When undertaking an engine build of this magnitude, it's crucial to ensure all supporting components are up to the task. This includes the engine block, cylinder heads, fuel system, and cooling system. Proper assembly and tuning are also paramount to achieving the desired performance and reliability. Please note that this kit is not CARB approved and cannot be shipped to California.
