The Tomei Forged Billet Full Counterweight Crankshaft for the SR20DET is a high-strength stroker crankshaft engineered for serious high-performance and motorsports applications. Featuring a 91.0mm stroke, this crankshaft increases displacement to approximately 2.2L, delivering improved torque and power potential across the RPM range.

Manufactured from forged billet material and designed with a full counterweight configuration, this crankshaft provides exceptional rigidity, balance, and durability under extreme engine loads. The increased stroke improves mid-range and low-end torque while maintaining the SR20DET’s high-revving characteristics, making it ideal for high-boost street, drag, and circuit applications.
