AMS ALPHA Nissan R35 GT-R Throttle Body Porting Service

Recently we have been talking about some small additions to our part catalog that helped us achieve power beyond that of the ALPHA 12. During testing on our ALPHA 12 car on low boost we saw GREAT improvements in HP and torque across the entire power band. For those looking for a bump in power on any level of GT-R our throttle body porting service is the way to go! We have ported cores on the shelf ready to go for exchange!!!

The AMS Nissan R35 GT-R CNC Ported Throttle Body Service offers solid performance gains and improved throttle response coupled with OEM drivability. Using precision CNC machining, we increase the stock throttle body diameter from 60mm to 63mm providing a 10% increase in airflow area resulting in more horsepower. Your throttle blade shafts are then EDM thinned (Electrical Discharge Machining) to remove excess material. The result is even better flow and less turbulence to provide maximum airflow under wide open throttle. You can expect up to 40HP gains depending on engine configuration from this simple yet very effective service.


  • 10% increase in flow area over stock throttle body
  • EDM thinned throttle body shaft for better flow and less turbulence
  • Improved throttle response
  • Up to 40HP gains depending on engine configuration
