Benefits of a Stroker Engine in a Nissan R35 GT-R:
• Increased displacement: A stroker kit can raise engine displacement, for instance, from 3.8L to 4.1L.
• Improved engine responsiveness: A stroker kit enhances the overall engine response.
• Higher horsepower: Stroker engines can deliver a significant increase in horsepower.
• Increased fuel/air mixture: A longer stroke allows for a larger fuel/air charge.
• Boosted torque: A longer stroke results in greater torque output.

Production Notes:

• *Advertised horsepower, torque, and RPM limits are approximations and can vary greatly depending on factors such as turbo choice, intake and exhaust restrictions, and fuel type. Optimal conditions with proper mods are required for these numbers, and individual results may differ.
• In the rare event of supply chain delays, our component selection may differ from what’s advertised. Any necessary substitutions will be communicated by your AMS Sales Representative during the assembly.
• A good condition core, including a usable block, crank, engine girdle, and oil squirters, is required for the build.

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:
At AMS, each of our built engines is carefully handcrafted with the same precision as the ones used in our record-breaking race cars. When you opt for an AMS engine, you’re investing in over two decades of experience, with thousands of race engines assembled to date. Like in our 3000+ WHP race cars, each engine is balanced, blueprinted, and assembled to exact specifications. Before the assembly begins, we inspect each block for correct dimensions, cylinder bore, main alignment, and flatness, ensuring you receive the strongest foundation for your engine build. Every engine comes with a spec sheet where tolerances, torque specs, and clearances are logged as part of our stringent quality control process.
