Fidanza 88-00 Sentra SR20 / 91-93 NX / 95-98 200SX / 91-02 Infiniti G20 2.0L Aluminum Flywheel

Crafted from billet 6061 T6 or 2024 T4 aluminum, this Fidanza flywheel is designed to significantly reduce rotational mass. Its lower MOI (moment of inertia) means the engine can rev up and down much faster, translating to quicker acceleration and a more responsive throttle feel. This is a popular upgrade for owners looking to get more out of their 2.0L SR20 engine, especially when paired with other performance modifications.

Fidanza builds these flywheels with a heat-treated friction plate for reliable grip and long life, and it's designed to be replaceable. The ring gear is made from hardened 1050 steel, ensuring durability for engagement with your starter. Military-spec fasteners are used for added reliability, meaning this part is well-built for the demands of spirited driving.

This flywheel is notably lighter than stock, often 40-60 percent less, which directly contributes to improved acceleration. The stepped dowels on most applications ensure it fits right onto your existing setup, making it a straightforward bolt-on replacement for your original flywheel.
