BTR Stage 3 Turbo Camshaft For 5.3/6.0 Builds
The BTR Stage 3 cam is designed for higher RPM response in light-weight turbo setups. Specs of 224/24x with .618″ lift and 114 LSA strike a balance between aggressive intake/exhaust timing and streetable driveability. Includes BTR Platinum dual springs with titanium retainers and 7.400″ chromoly pushrods, suitable for 4.8/5.3/6.0/6.2 LS engines paired with turbo kits. This cam targets a robust power increase without excessive overlap in boost applications.
BTR Stage 2 Turbo Camshaft With Titanium Retainers
The Stage 2 turbo cam from BTR is tuned for more RPM than Stage 1, offering duration around 226/231 with .610″/.609″ lift and 113 LSA. It uses BTR’s dual springs with lightweight titanium retainers and 7.400″ chromoly pushrods, matching LS1/LS2/LS3 families (and LQ4/LQ9 LM7 variants). This kit is well-suited for boosted builds that demand stronger top-end performance while preserving driveability at lower speeds.
BTR Stage 4 Turbo Camshaft With Premium Kit
The Stage 4 cam is the “big stick” option for turbocharged LS builds. Specs 234/239 with .612″/.610″ lift and 115+5 LSA, paired with a 3-bolt timing gear pattern. This setup aims for substantial top-end power, ideal for high-boost configurations and performance-focused street/drag applications. The included components emphasize durability under aggressive boost, making it a strong choice for LT4-style or similar turbo setups.
Texas Speed Stage 3 Turbo Cam Kit For Cathedral Port LS
This Texas Speed Stage 3 Turbo Cam is designed for boosted cathedral-port 4.8/5.3/6.0 platforms. Specs 218/224 with .600/.600″ lift and 113+3 LSA, and it includes a dual spring kit with titanium retainers and 7.400″ chromoly pushrods. The kit also provides a gasket set, making it a more complete upgrade for boosted street machines seeking improved throttle response and mid-to-high RPM power.
Texas Speed CHOPacabra Cam Kit For LS Trucks
The CHOPacabra cam is a punchy, snarling option designed for a turbocharged LS truck setup. Specs 214/222 with .550/.550 lift and 108 LSA. The kit typically includes seals, pushrods, and springs, making it a compact, all-in-one boost-focused upgrade for LS-powered trucks seeking a fierce, aggressive cam profile with strong mid-range performance.
Buying Guide: Key Purchase Considerations
- Engine family and head compatibility: Ensure the cam is designed for LS platforms you own (LS1/LS2/LS3, cathedral port, or rectangular port heads) and matches turbo kit specifications.
- Cam specs and boost strategy: Compare lift, duration, and LSA to align with your boost level and turbocharger choice. Higher lift and wider LSA can increase top-end power but may impact low-end vacuum and drivability.
- Spring and pushrod compatibility: Some cams ship with springs and titanium retainers; others require separate purchases. Verify the exact spring rates and pushrod lengths (e.g., 7.400″ chromoly) to avoid valvetrain interference.
- Gear pattern and timing: Many options specify a 3-bolt timing gear pattern; confirm your crank gear compatibility and timing cover setup to prevent installation issues.
- Intended use and reliability: For street-driven cars, choose cams offering a balance of street manners and power. For drag-focused builds, prioritize top-end RPM and peak power potential.
- Kit completeness: Some listings include gaskets, seals, and pushrods; others are cam-only. A complete kit can simplify installation and reduce additional parts sourcing.
- Installation considerations: Upgrades often benefit from accompanying EFI tuning, fuel system adjustments, and spark management to maximize gains and maintain engine safety under boost.
- Budget and maintenance: Higher-duration cams with titanium retainers can add cost but improve rpm capability; consider long-term maintenance when choosing.
