Brian Crower Nissan RB26/RB25 Stroker Kit - 73.7mm Stroke Billet Crank 86.5mm 16.1cc Pistons

Starting with a 73.7mm stroke from a billet crankshaft is the foundation of this Brian Crower stroker kit for Nissan RB26 and RB25 engines. This isn't just about adding a few cubic inches; it's about fundamentally changing the engine's breathing and torque characteristics. The billet crank is forged from high-grade steel, then precision machined to ensure it can handle the increased stresses that come with a larger displacement and higher performance output. This robust construction is key for building a reliable, powerful engine.

The kit includes 86.5mm pistons with a 16.1cc dish volume, carefully designed to work with the new crank and achieve optimal compression ratios when paired with appropriate cylinder heads. Brian Crower is known for using well-built components, and this kit reflects that. The pistons are made from forged aluminum, which is strong enough for high-boost applications while keeping weight down. This combination of a strong billet crank and lightweight forged pistons helps the engine rev more freely while producing significantly more torque across the entire RPM range.

When undertaking an engine build of this magnitude, it's crucial to ensure all supporting components are up to the task. This stroker kit is designed for serious engine builds where maximum performance and reliability are paramount. Remember that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and consult with a professional engine builder to ensure all components are installed correctly for optimal performance and longevity.
