Brian Crower Nissan SR20DE(T) Stroker Kit 91mm Stroke Billet Crank H-Beam Rod (5.366) Custom Pistons

Brian Crower is well-known for making strong internal engine components. This stroker kit is built for the Nissan SR20DE and SR20DET engines, commonly found in performance-oriented vehicles like the Infiniti G20, Nissan 240SX, and Sentra. If you're looking to increase the displacement of your SR20, this kit is a solid foundation for building more power and torque. It includes a 91mm stroke billet crankshaft, H-beam connecting rods with a length of 5.366 inches, and custom-spec pistons designed to work together for improved performance.

The heart of this kit is the 91mm stroke billet crankshaft. Billet cranks are machined from a solid block of steel, making them significantly stronger and more durable than cast or forged cranks, especially under high stress. This increased stroke length, combined with the robust H-beam connecting rods, effectively increases the engine's displacement. This means more air and fuel can be burned with each combustion cycle, leading to a substantial increase in both horsepower and torque across the entire RPM range. The custom pistons are designed to complement the new stroke and rod length, ensuring proper compression ratios and piston-to-wall clearance for reliable operation.

When installing a stroker kit, it's important to ensure all components are balanced as a rotating assembly. This kit is designed to work with the SR20DE(T) engine, but careful attention to machining, balancing, and assembly is crucial for longevity and performance. This kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation guide for specific procedures and recommendations.
