{"product_id":"sr20det-91-0mm-crankshaft","title":"SR20DET 91.0mm Crankshaft","description":"Introducing the Tomei Crankshaft for the Nissan SR20DET, a precision-engineered component designed for serious performance enthusiasts and motorsports applications. This crankshaft features a 91.0mm stroke, increasing displacement to approximately 2.2L, which delivers improved torque and power potential across the RPM range.\n\nManufactured 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 enhances 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.\n\nInstallation requires compatible stroker pistons and connecting rods. Balancing and clearance verification are necessary during assembly. It is recommended for use with upgraded oiling and valvetrain systems, and ECU tuning is required after installation. Professional engine assembly is also recommended for optimal results.\n\nFitment is designed for Nissan SR20DET engines, including various Silvia (1988-2002), 180SX (1989-1999), and 240SX (1989-1998) models. This crankshaft is intended for custom engine builds and stroker applications, with additional machining and supporting components likely required.","brand":"Tomei","offers":[{"title":"Default Title","offer_id":52873016607032,"sku":"TA204B-NS08A","price":2160.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/sr20det-91-0mm-crankshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
