Benefits of a R35 GTR Stroker Engine Build:
Upgrading to a stroker engine in a Nissan R35 GT-R results in improved engine response and higher horsepower. The stroker kit increases engine displacement, such as from 3.8L to 4.1L, boosting the engine’s power potential. A longer stroke allows for greater fuel/air intake, delivering more torque at lower RPMs. However, this comes at the cost of high RPM performance, as the extended piston travel can limit responsiveness. A longer stroker crankshaft increases engine size and airflow, ultimately leading to enhanced horsepower.

• *Horsepower, torque, and RPM limits can vary based on numerous factors like turbocharger size, intake/exhaust flow, and fuel quality. The advertised numbers are based on optimal setups but may differ with individual configurations.
• In rare instances, component choices may be affected by supply chain issues. If substitutions are necessary, they will be communicated in advance through your AMS Sales Representative.
• For builds, we require a long block core in good condition. Please ship the long block fully assembled, including valve covers, oil pan, timing covers, and crank pulley to prevent missing parts. Any parts not fit for reuse will be quoted for replacement during the build 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.
