Brian Crower Crankshaft - Nissan SR20DE(T) 91mm Stroke 4340 Billet

This is a Brian Crower 91mm stroke crankshaft specifically for Nissan SR20DE and SR20DET engines, fitting a range of vehicles including the 1991-2002 Infiniti G20, 1995-1998 Nissan 200SX, 1989-1998 Nissan 240SX, 1991-1993 Nissan NX, and 1991-1994, 1998-2001 Nissan Sentra. If you're building a high-performance SR20 engine, whether naturally aspirated or turbocharged, a strong crankshaft is the foundation of your build. This component is critical for handling increased cylinder pressures and RPMs that come with performance modifications.

Brian Crower crafts this crankshaft from a solid piece of 4340 billet steel, a material known for its exceptional strength and durability under extreme stress. The 91mm stroke is an increase over the stock dimension, which helps to increase displacement and can improve torque output. This billet construction means it's forged from a single block of steel, making it significantly stronger and more reliable than cast crankshafts, especially important when pushing an engine beyond its original limits. The precision machining ensures it fits right and balances properly for smooth operation at high RPMs.

When undertaking an engine build of this caliber, it's essential to ensure all supporting components are up to the task. This crankshaft is designed to handle the demands of a performance SR20 build, but remember to consult with your engine builder or refer to Brian Crower's installation guidelines for proper balancing, bearing selection, and assembly procedures. A well-built crankshaft is key to unlocking the full potential of your SR20 engine.
