The Tomei Engine Stroker Crankshaft (part number TA204B-NS08A) is a forged full-counterweight unit with a 91.0 mm stroke (5.0 mm longer than stock), designed to convert the SR20 into a 2.2-liter SR22 combination when paired with the correct matching pistons.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eForged from high-strength alloy and finished as a full-counterweight design, this crankshaft provides the rigidity and balance characteristics needed for higher-displacement, higher-output applications. The increased stroke delivers stronger low- and mid-range torque while still allowing the engine to take advantage of larger turbochargers at higher RPM. At approximately 18 kg, it remains practical for performance street and track builds. Special Tomei or compatible stroker pistons are required—this crankshaft cannot be used with standard-stroke SR20 pistons.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThis 91 mm forged crankshaft is a core component for serious SR22 stroker projects based on the S13 Silvia or 180SX. Professional machining, balancing, and assembly are essential for correct installation. At Terra Firma Automotive, we supply this genuine Tomei SR22 Stroker Crankshaft as a high-quality foundation for increased-displacement SR builds. Whether the goal is stronger response, greater torque, or more headroom for larger turbos, this crank delivers the material quality and dimensional accuracy associated with Tomei. Choose Terra Firma Automotive for authentic Japanese engine internals that support capable 2.2-liter SR combinations.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Tomei Stroker Crankshaft\u003c\/li\u003e\n\u003cli\u003ePart Number: TA204B-NS08A\u003c\/li\u003e\n\u003cli\u003eApplication: Nissan S13 Silvia \/ 180SX (SR22 conversion)\u003c\/li\u003e\n\u003cli\u003eStroke: 91.0 mm (stock 86.0 mm)\u003c\/li\u003e\n\u003cli\u003eCreates 2.2-liter (SR22) displacement\u003c\/li\u003e\n\u003cli\u003eFull-counterweight design\u003c\/li\u003e\n\u003cli\u003eForged alloy construction\u003c\/li\u003e\n\u003cli\u003eApproximate weight: 18 kg\u003c\/li\u003e\n\u003cli\u003eRequires special matching stroker pistons\u003c\/li\u003e\n\u003cli\u003eNot compatible with standard-stroke SR20 pistons\u003c\/li\u003e\n\u003cli\u003eIncreased low- and mid-range torque potential\u003c\/li\u003e\n\u003cli\u003eSupports higher-output and larger turbo applications\u003c\/li\u003e\n\u003cli\u003eRequires professional machining and assembly\u003c\/li\u003e\n\u003cli\u003eTrusted Japanese crankshaft engineering\u003c\/li\u003e\n\u003cli\u003eAvailable from Terra Firma Automotive\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tomei","offers":[{"title":"Default Title","offer_id":18507068145726,"sku":"TA204B-NS08A","price":2160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1992\/7247\/products\/121008.jpg?v=1622208885","url":"https:\/\/tfaspeed.com\/products\/tomei-engine-stroker-2-2l-crankshft-sr22-91mm-for-nissan-s13-silvia-180sx-ta204b-ns08a","provider":"Terra Firma Automotive","version":"1.0","type":"link"}
