BTR Stage 3 Turbo Camshaft Kit With Springs
The BTR Stage 3 Turbo Camshaft Kit is designed for LS engines running forced induction and seeks to maximize RPM potential while maintaining a stable valvetrain. It features a cam profile of 224/24x with lift around .618 inches and a 114 LSA, paired with platinum dual springs and lightweight titanium retainers. The kit includes 7.400″ chromoly pushrods and a 3-bolt timing gear pattern for a robust setup. Ideal for lighter cars needing strong RPM performance from a 5.3/6.0 S400 combo.
CHOPacabra Cam Kit With Springs
The CHOPacabra cam by Texas Speed is crafted for LS trucks and offers a nasty, snarling idle with improved torque under boost. Specs include 214/222 duration with .550 lift and a 108 LSA, designed to work with LS6 valve springs and a factory torque converter. The included springs, seals, and OE replacement pushrods ensure a straightforward install. This cam is a strong choice for a stock-to-mildly modified truck that requires brisk response and noticeable power gains under boost.
BTR Stage 2 Turbo Camshaft Kit
The BTR Stage 2 kit is a step up from Stage 1, designed to pull more RPM and deliver added midrange power for turbocharged LS builds. It features a 226/231 duration with lifts around .610/.609 inches and a 113 LSA. A 3-bolt timing gear pattern is included, along with the same 7.400″ chromoly pushrods and platinum dual springs with titanium retainers. This kit suits lighter cars seeking a balanced blend of street manners and track-capable power when boosted.
SUSUCAR Sloppy Stage 2 Kit for LS
This stage 2 kit from SUSUCAR provides a complete cam package for Gen 3/4 LS engines, including camshaft, springs, seals, pushrods, and gaskets. Specs show a 228/230 duration with about 0.585 inch lift and a 112 LSA. The kit is designed to work with 3-bolt cams and is compatible with a wide range of LS engines from 4.8 to 6.2 liters. Its all-in-one approach makes it a convenient option for builders seeking a reliable turbo-friendly upgrade with a strong mid-range presence.
BTR Stage 4 Turbo Camshaft Kit
The Stage 4 turbo cam from BTR marks the higher end of the turbo cam spectrum. It features a robust 234/239 duration with lift around .612/.610 inches and a 115+5 LSA, plus a 3-bolt timing gear pattern. The kit emphasizes maximum turbo performance, offering a strong torque curve and substantial top-end power for Turbo LS builds. Combined with the BTR dual springs and titanium retainers, this option targets boosted engines that demand peak sustained power and reliability under heavy load.
Buying Guide: Key Purchase Considerations
- Engine configuration and goal: Align cam duration, lift, and LSA with your turbo setup, compression ratio, and gearing. Longer duration typically favors higher RPM and top-end power, while a wider LSA can improve off-boost stability.
- Springs and valvetrain: For boosted engines, select springs designed for turbo preloading and valve train stability. Titanium retainers reduce weight, lowering valve train inertia and aiding high-RPM operation.
- Pushrods and geometry: Match pushrod length (commonly 7.400″) to the cam and cylinder head geometry to ensure correct valve timing and avoid coil bind or retainer contact.
- Kit completeness: Some cam kits include springs, seals, and pushrods, while others are camshaft-only. For a smoother install, consider full kit offerings that fit your target engine family (LS1/LS2/LS3, etc.).
- Fuel system and tuning: Turbo cams affect boost onset and fueling needs. Ensure your ECU calibration accounts for the cam profile, and plan for necessary fuel upgrades and intercooling where applicable.
- Vehicle use and durability: For daily drivers, balance power with reliability, choosing cam profiles that maintain drivability and tractable torque. For track-only builds, favor profiles with higher rpm capability and stronger midrange.
- Compatibility: Confirm compatibility with your engine variant (4.8, 5.3, 6.0, 6.2, etc.), 3-bolt timing gear patterns, and existing valvetrain components to minimize fitment issues.
- Budget and maintenance: Higher-performance cams may demand stronger supporting components and more frequent maintenance. Assess total cost including springs, pushrods, gaskets, and tuning.
- Tuning support: Opt for cams with established synergy for boosted LS configurations and consider professional dyno tuning to maximize safe, reliable power.
In summary, turbo cam choices for LS engines balance duration, lift, LSA, and supporting parts to deliver the desired blend of power, response, and reliability. The products highlighted here cover a spectrum from aggressive Stage 2 to Stage 4 setups, paired with robust valve springs and pushrods to ensure workable performance under boost. Always verify compatibility with your specific vehicle and seek professional tuning guidance for optimal results.
