2009-2021 Nissan GT-R

The AMS Alpha Series Camshafts are engineered specifically for turbo-upgraded VR38 engines, delivering massive horsepower gains, improved turbo response, and excellent street drivability. Designed for both bolt-on and full-turbo setups, these camshafts are the result of extensive R&D and testing on world-record Alpha GT-Rs.

Optimized Power Across the Rev-Range

Unlike traditional cam upgrades that focus solely on peak horsepower, AMS engineers designed the Alpha cams to provide:

• Maximum usable power throughout the rev range

• Enhanced low-end torque for quicker spool and acceleration

• Smooth, driveable street manners even with large turbo setups

This means you get massive power gains without sacrificing turbo response or drivability.

Proven Record-Breaking Performance

These are the same camshafts that powered AMS’s World Record Alpha 12 and Alpha Omega GT-Rs, achieving:

• 8.62 @ 173.8 mph in the quarter mile (Alpha Omega, 1500HP)

• 3.31 seconds 60–130 mph (Alpha 12)

These results demonstrate unmatched power delivery, turbo spool, and reliability under extreme conditions.

Power Gains

Depending on turbo selection and boost levels, the Alpha Series Camshafts can produce:

• 30–100 HP gains over stock camshafts

• Excellent response for both street and track use

• Smooth spool-up for large turbo setups without lag
