Brian Crower Nissan RB26/RB25 Stroker Kit - 79mm Stroke Billet Crank Custom Pistons Rods 4.783 inch

Brian Crower is well-known for making serious engine components for performance applications, and this stroker kit for Nissan RB26 and RB25 engines is a prime example of their work. If you're looking to significantly increase the displacement and torque output of your RB engine, this kit is designed to do just that. It centers around a 79mm stroke billet crankshaft, which is the core component that allows for the increased displacement.

This kit includes custom-forged pistons designed to work with the new stroke and your specific cylinder head configuration, along with strong 4.783 inch connecting rods. The billet construction of the crankshaft means it's machined from a solid piece of steel, making it incredibly strong and resistant to the stresses of high-performance engines. This is crucial for reliability when you're pushing an engine beyond its original design parameters. The custom pistons are typically designed for optimal compression ratios and combustion chamber shapes, working in harmony with the new crank and rods to maximize power and efficiency.

When undertaking a stroker build like this, it's important to note that this kit is not CARB approved and cannot be shipped to California. You'll want to ensure you have all the necessary supporting modifications and a solid plan for assembly, as this is a significant engine modification. This kit is a foundational piece for building a high-horsepower RB engine.
