Show original supplier description
The Tomei TA201A-NS01A Stroker Kit is engineered to significantly enhance the performance of the Nissan VR38DETT engine. By increasing the engine's bore from 95.50mm to accommodate a 94.40mm stroke, this kit effectively raises the displacement to 4057cc, resulting in a substantial gain in low-end torque and overall horsepower. This upgrade is built upon Tomei's extensive racing heritage, ensuring components can withstand the extreme demands of high-performance applications. Constructed with fully forged pistons, connecting rods, and crankshafts, this stroker kit offers superior durability and strength compared to standard cast factory components. Forged metal is significantly more resistant to fracture under extreme conditions and heat, providing the peace of mind needed to push an engine to its limits. Tomei's meticulous attention to detail means all components are precisely machined to strict tolerances, enhancing airflow, ensuring proper fitment, and guaranteeing a reliable seal for catastrophic engine failure prevention. This stroker kit is specifically designed for the Nissan VR38DETT engine found in various GT-R models. Fitment has been confirmed for multiple model years, including 2009 through 2023, and specific trims like the Nismo AWD. It is crucial to confirm exact vehicle compatibility before purchase, as the search functionality on retail sites can help verify precise fitment for your specific GT-R.
