What is the advantage of a 91mm stroke crankshaft?

A 91mm stroke crankshaft increases the engine's displacement compared to the stock dimension. This change can alter the engine's powerband and potentially increase overall power output when combined with other performance modifications.

What material is this crankshaft made from and why is it important?

This crankshaft is forged from 4340 billet steel. This is a strong and durable material commonly used in performance engine components because it can withstand the higher stresses and loads associated with increased horsepower and torque.

What other components are typically needed for a crankshaft replacement like this?

When installing a performance crankshaft, it's crucial to have the correct pistons and connecting rods that match the stroke and bore. Proper engine block preparation, including clearancing, and high-quality bearings are also essential for a successful build.

Product Details

Brian Crower is well-known for building robust internal engine components, and this 91mm stroke crankshaft for the Nissan SR20DE(T) engine is a prime example of their work. If you're looking to rebuild or significantly upgrade the bottom end of your 1991-1996 or 1999-2002 Infiniti G20, or your 1995-1998 Nissan 200SX, 1989-1998 Nissan 240SX, 1991-1993 Nissan NX, or 1991-1994/1998-2001 Nissan Sentra, this crankshaft is designed to handle increased power and stress.

This crankshaft is forged from 4340 billet steel, a strong material chosen for its durability under high loads. The 91mm stroke is an increase over the stock dimension, which will change the engine's displacement and can affect its powerband. This component is a critical piece for anyone building a high-performance SR20 engine, whether for track use, drifting, or a powerful street build. The precision machining ensures it will fit right into your engine block with the proper preparation and assembly.

When undertaking a build of this magnitude, it's essential to ensure all supporting components are up to the task. This includes proper piston and connecting rod selection, as well as ensuring your engine block is clearanced and prepared correctly. Always refer to the manufacturer's detailed installation instructions for specific requirements and recommendations to ensure a successful build.
