Brian Crower Nissan VQ35HR Stroker Kit 86.4mm Billet Crank Sportsman Rods 5.974in Unbalanced Pistons

Brian Crower is well-known for making strong internal engine components that can handle serious performance. This stroker kit is a prime example, designed to increase the displacement of your Nissan VQ35HR engine. By increasing the stroke from 81.4mm to 86.4mm, you're effectively making your engine larger, which generally leads to more power and torque potential. This kit is a popular choice for enthusiasts looking to build a more powerful VQ35HR for applications like the 350Z, G35, or FX35.

At the heart of this kit is a Brian Crower 86.4mm billet crankshaft. Billet cranks are machined from a solid block of steel, making them incredibly strong and resistant to flexing under high loads, which is crucial when you're increasing displacement and aiming for more power. It comes paired with Brian Crower's 5.974-inch Sportsman connecting rods. These rods are also well-built for performance, featuring a robust design to handle the increased forces. The kit includes unbalanced pistons, meaning you'll need to balance them with your specific crankshaft and rotating assembly during the build process. This allows for precise balancing tailored to your exact setup.

This stroker kit is designed to fit a range of Nissan and Infiniti vehicles equipped with the VQ35HR engine, including models like the 2007-2009 Nissan 350Z, 2008-2012 Infiniti EX35, and 2009-2012 Infiniti FX35. When undertaking a build like this, it's important to ensure all components are properly balanced and that your engine block is clearanced for the longer stroke. You'll also want to consider supporting modifications like upgraded fuel systems, engine management, and potentially a performance camshaft to take full advantage of the increased displacement. Please note that this kit is not CARB approved and cannot be shipped to California.
