Kelford 231-A 266/266 Stage 1 Camshafts for Nissan GT-R R35 VR38DETT
Take your Nissan GT-R R35 VR38DETT engine build to the next level with the Kelford 231-A 266°/266° Stage 1 EZ-Power Camshaft Set.
Developed specifically for the legendary Nissan VR38DETT twin-turbo V6 engine, the Kelford 231-A camshaft profile is an excellent choice for GT-R owners looking for increased performance without sacrificing the drivability required from a road-going performance car.
Kelford designed the 231-A Stage 1 VR38DETT cams for stock engines fitted with bolt-on performance upgrades. They are particularly well suited to street and fast-road Nissan GT-R builds producing approximately 600hp to 1000hp with either stock or bolt-on turbocharger combinations.
The 266° intake and 266° exhaust profiles provide an effective balance between improved engine performance and everyday usability, making the 231-A one of the most attractive Kelford camshaft upgrades for modified R35 GT-Rs.
Designed for High-Performance Street GT-R Builds
Not every modified Nissan GT-R requires an aggressive motorsport camshaft.
The Kelford 231-A has been developed to provide additional performance potential while maintaining the characteristics important for a road-driven R35, including:
- Strong throttle response
- Good low and mid-range manners
- Predictable street drivability
- Compatibility with common bolt-on modifications
- Excellent performance potential with upgraded engine calibration
This makes the 231-A an excellent choice for owners building a powerful but usable VR38DETT-powered Nissan GT-R.
Suitable for 600–1000HP VR38DETT Builds
Kelford recommends the 231-A profile for VR38DETT combinations in approximately the 600hp–1000hp range using stock or bolt-on turbochargers.
This makes the camshaft set particularly suitable for GT-R builds incorporating upgrades such as:
- Performance intake systems
- Upgraded exhaust systems
- High-flow downpipes
- Upgraded intercoolers
- ECU tuning
- Fuel-system upgrades
- Stock-frame performance turbochargers
- Bolt-on turbo upgrades
- Supporting VR38DETT engine modifications
The exact power achieved will depend on the complete engine specification, turbocharger combination, fuel, boost pressure, ECU calibration and supporting modifications.

OEM Valve Spring Compatibility
One of the major benefits of the Kelford 231-A VR38DETT camshaft set is that it can be used with the factory Nissan valve springs when the original boost pressure and RPM limit are retained.
For engines with higher mileage, Kelford recommends upgrading to the KVS38-BT valve spring kit.
Engines operating at increased RPM, higher boost or with substantial additional engine modifications should have the complete valvetrain specification assessed by an experienced VR38DETT engine builder.
Why Upgrade Your Nissan GT-R with Kelford Camshafts?
The VR38DETT responds extremely well to performance modifications, but as airflow demand increases, the factory camshaft profile can eventually become a limiting factor.
Installing performance camshafts can improve the engine’s ability to move air through the cylinder heads, supporting increased power potential when combined with the appropriate turbocharger, fuel and ECU upgrades.
The Kelford 231-A is particularly attractive because it is engineered as a Stage 1 profile rather than an extreme race-only camshaft.
For many high-performance road-going R35 builds, this provides an excellent balance between:
Performance + response + drivability + reliability
Why Choose Kelford Cams?
Kelford Cams is one of the recognised names in high-performance camshaft and valvetrain development, producing performance profiles for a wide range of Japanese performance engines.
The VR38DETT camshaft range includes multiple profiles designed for everything from street-driven GT-Rs to extreme drag and roll-racing applications.
The 231-A sits at the street-performance end of the range, making it an excellent starting point for owners who want improved VR38DETT performance while retaining a responsive and usable GT-R.

Installation Advice
Performance camshaft installation should be undertaken by an experienced engine builder or specialist familiar with the Nissan VR38DETT engine.
Correct camshaft timing, valve clearance and valvetrain setup are essential.

Exhaust: 0.33mm
Always follow the latest Kelford installation and specification information when assembling the engine.
