Benefits of a Stroker Engine in a Nissan R35 GT-R:
The benefits of a stroker engine in a Nissan R35 GT-R include improved engine response and increased horsepower, primarily achieved through increased displacement. For instance, a stroker kit can enhance the engine's displacement from 3.8L to 4.3L, allowing for a greater fuel/air charge. This design results in increased torque, particularly in the low rev range. However, it's important to note that while stroker kits provide more torque, they can also hinder the engine's ability to reach high revs due to the increased piston travel, potentially decreasing overall responsiveness. By utilizing a stroker crankshaft with longer throws, the engine can increase its size and capacity for air movement, ultimately boosting horsepower.

Production Notes:

• *Horsepower and torque figures, as well as RPM limits, are estimates and can vary widely based on several factors, including turbocharger selection, intake and exhaust restrictions/backpressure, and fuel quality and octane. The figures provided are based on optimal conditions and appropriate supporting modifications but generally represent attainable results for the average customer. Individual results may differ.
• In rare instances, our component selection may deviate from what's advertised due to supply chain delays. Any component substitutions will be communicated beforehand by your AMS Sales Representative during the engine assembly process.
• No core components are required for the Stage 6 Billet Pro Mod Short Block.

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.

Benefits of an AMS Built Engine:
All our built engines at AMS are meticulously handcrafted with the same precision used in our world-record-setting race cars. When you select an AMS engine, you are investing in over 20 years of expertise gained from assembling thousands of race engines. Each engine, just like those in our 3000+ WHP race cars, is balanced, blueprinted, and assembled according to our exact specifications. Prior to assembly, each block undergoes thorough checks for dimensions, cylinder bore, main alignment, block flatness, and more, ensuring you receive the strongest foundation for your new engine. Additionally, every assembled engine comes with an archived spec sheet documenting tolerances, torque specifications, and clearances as part of our rigorous quality control process.
