Brian Crower BMW B58B30M Gen 1 Stroker Kit - 100mm Stroke/ProH625+

If you're looking to significantly increase the displacement and power output of your BMW B58B30M Gen 1 engine, a stroker kit is the way to go. This kit from Brian Crower is designed to give your engine a substantial boost in torque and horsepower by increasing the stroke length. It's a serious upgrade for those building a high-performance engine where every bit of power matters.

This particular stroker kit features a 100mm stroke, which is a notable increase over the stock dimension, effectively raising the engine's displacement. The kit includes a forged crankshaft, connecting rods, and pistons, all engineered to work together seamlessly. The connecting rods are made from ProH625+ material, known for its exceptional strength and durability under high stress, which is crucial for a stroker build. The crankshaft is also forged for maximum strength. This combination allows your engine to handle significantly more power than it could from the factory.

When undertaking a stroker build like this, it's important to consider that this is a comprehensive engine modification. You'll need to ensure all supporting components, such as the engine block, cylinder head, and fuel system, are up to the task of handling the increased power and torque. This kit is a well-built foundation for a powerful B58 engine, but it requires careful assembly and tuning to achieve its full potential. Please note that this kit is not CARB approved and cannot be shipped to California.
