Benefits of a R35 GTR Stroker Engine Build:
A stroker engine provides significant benefits, such as enhanced engine response and higher horsepower. Installing a stroker kit increases engine displacement, for example, from 3.8L to 4.1L, allowing the engine to produce more power. The longer stroke enables a greater fuel/air charge, leading to improved torque, particularly in the lower rev range. However, the extended piston travel may limit the engine's ability to achieve high RPMs, which can reduce overall responsiveness. The stroker crankshaft’s longer throws expand engine size, moving more air and boosting horsepower.

• * The horsepower, torque, and RPM limits listed are estimates and may vary due to numerous factors such as turbocharger selection, intake and exhaust setups, and fuel type. These values are based on optimal conditions with proper modifications, but results may differ.
• Occasional supply chain delays may lead to component substitutions. Your AMS Sales Representative will notify you of any changes during the engine build.
• A good-condition core long block is required for the build. Ensure it is shipped fully assembled, including valve covers, oil pan, timing covers, and crank pulley. Any non-reusable components will be quoted for replacement during the process.

Shipping Times:
Please note that all engines are built to order and can take 2-8 weeks. Please call to confirm a more precise ETA.
