Benefits of a Stroker Engine in a Nissan R35 GT-R:
A stroker engine offers improved engine response and increased horsepower. By using a stroker kit, the engine's displacement can be enhanced, from 3.8L to 4.3L, which contributes to a greater fuel and air charge. This longer stroke not only boosts horsepower but also results in increased torque, delivering a more powerful and responsive driving experience.

Production Notes:

• *Horsepower, torque, and RPM limits are general estimates and may vary significantly depending on turbo selection, intake/exhaust configuration, fuel quality, and more. Advertised numbers are based on ideal conditions with proper mods, though your individual results may vary.
• On rare occasions, supply chain delays may result in component changes. Any substitutions will be communicated ahead of time by your AMS Sales Representative.
• We assume a good condition core is sent for the build, including a usable block, crank, engine girdle, and oil squirters.

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:
Every engine we build at AMS is handcrafted with the same care and precision as those used in our world record-setting race cars. By choosing an AMS engine, you’re gaining the benefits of over 20 years of expertise, with thousands of race engines assembled. Just like our 3000+ WHP race cars, every motor is carefully balanced, blueprinted, and assembled according to our exact specifications. Before assembly, each block undergoes a detailed inspection for dimensions, cylinder bore, main alignment, and block flatness to ensure you get the strongest possible foundation. Every engine is delivered with an archived spec sheet documenting the tolerances, torque specs, and clearances for our quality control process.
