Product Description
Brian Tooley Racing BTR Twin Turbo Stage 2 Camshaft V2 for LS-Based Engines
222/24x Duration | .618"/.618" Lift | 113 LSA | 3-Bolt Pattern
The Brian Tooley Racing Twin Turbo Stage 2 Camshaft V2 is designed for 1997-2013 LS-based 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L engines running 58mm to 65mm turbochargers. Its versatile profile delivers a relatively mild idle in larger 6.0L and 6.2L combinations while producing a more aggressive exhaust note in smaller 4.8L and 5.3L engines. Available camshaft, spring, pushrod, retainer, and gasket package options make it easy to select the components needed for a street-driven or track-focused twin-turbo build.
Key Features & Benefits
- Twin Turbo Stage 2 V2 Profile: The 222/24x duration, .618-inch intake and exhaust lift, and 113-degree lobe separation angle create a turbo-focused camshaft profile for compatible LS-based combinations. Its 3-bolt configuration supports common performance camshaft installations and conversions.
- Designed for 58mm to 65mm Turbos: BTR developed the Stage 2 Twin Turbo Cam for combinations using turbochargers within the 58mm to 65mm range. This makes it a targeted choice for builders who have moved beyond a mild turbo cam but do not require a more aggressive profile.
- Street and Track Versatility: This camshaft is designed to remain comfortable during regular street driving while supporting trips down the quarter mile. It provides a relatively mild idle in 6.0L and 6.2L engines, with a more aggressive-sounding idle in smaller 4.8L and 5.3L combinations.
- Broad LS-Based Engine Coverage: Compatibility includes 1997-2013 LS-based engines ranging from 4.8L through 6.2L. This application range makes the camshaft suitable for numerous twin-turbo LS car, truck, and engine-swap combinations using the required supporting components.
- Multiple Package Options: Choose the camshaft by itself or select packages with BTR Platinum .660-inch dual valve springs, valve seals, chromoly pushrods, and either steel or titanium retainers. A gasket option is also available with essential front-engine components for the camshaft installation.

Notes

- VVT-equipped engines require a VVT delete kit.
- Engines originally equipped with a 1-bolt camshaft require a 3-bolt conversion kit.
