Cold Fusion Nitrous presents a wet kit designed for GM powerplants including LT1, LS1, LS2, and LS3. It delivers up to 200 HP gains and includes jetting options for common horsepower shots (100, 125, 150, and 200). Built with high-quality components such as stainless braided hoses, a pro fogger nozzle, and robust solenoids, this kit provides precise fuel and nitrous control for those seeking substantial performance gains on LS platforms.
GM LS 78mm Plate Kit
The GM LS 78mm 3-Bolt Plate Kit from Nitrous Express is designed for LS engines with a 78mm throttle body. It includes a billet aluminum nitrous plate and a broad selection of horsepower jetting options, ranging from 50 to 400 HP at the wheels, with additional options up to 350 HP for solenoids. Installation is straightforward for LS builds, and the system integrates neatly between the throttle body and intake, offering both performance and aesthetic appeal for LS enthusiasts.
Motorcycle Dry Nitrous Kit
While primarily marketed for motorcycles, this 4-cylinder dry nitrous kit from Cold Fusion Nitrous demonstrates the dry approach’s flexibility and precision. It supports individual cylinder tunability by allowing nozzle placement in the airbox or throttle body. While not LS-specific, it reflects the broader dry nitrous technology and quality components that can influence design considerations for other platforms, including LS builds where applicable.
Nitrous Express Mainline Carb Nitrous Kit
Nitrous Express MainLine is a budget-friendly, rock-solid option for nitrous systems. While it is carbureted rather than a dry kit, it represents a robust platform for enthusiasts who want straightforward nitrous delivery. It emphasizes reliable performance with a focus on essential components and value, making it a practical entry point for those exploring nitrous on various engine setups, including LS builds with carbureted configurations or mixed setups.
Buying Guide: Key Considerations For LS Dry Nitrous Upgrades
- Engine compatibility: Confirm throttle body size, cylinder count, and fuel system compatibility to ensure the kit integrates cleanly with an LS engine and stock or upgraded EFI/TCU systems.
- Dry vs. wet configuration: Dry systems inject nitrous via the intake tract and rely on the engine’s fuel system. Wet kits add fuel directly with nitrous. For LS platforms, a dry approach can minimize fuel modifications, but peak power may require tuning and fuel-side adjustments.
- Preset and adjustable power levels: Look for kits offering adjustable nitrous output (e.g., 50–125 HP, up to 200+ HP) and compatible tuning options to match your goals and safety margins.
- Quality of components: Stainless steel hoses, high-capacity solenoids, and precision nozzles improve reliability and performance. Plate kits must mate well with the throttle body and intake to avoid vacuum leaks.
- Installation considerations: Factory-compatible wiring, EFI integration, and clear instructions reduce installation complexity. Some kits require only minor OEM harness interaction, while others may demand more extensive EFI recalibration.
- Maintenance and safety: Regular inspection of solenoids, hoses, jets, and fittings helps prevent leaks. Include proper safety interlocks and follow manufacturer guidelines for bottle pressure and storage.
- Support and warranty: Choose brands with solid technical support and documented warranty terms to address potential issues after installation.
Pro Tip: When selecting an LS dry nitrous option, prioritize kits that explicitly list LS compatibility and provide compatible nozzle or plate configurations for 78mm to 90mm throttle bodies, depending on your engine build. Always pair nitrous with a suitable fuel system upgrade and a trusted tune to protect the engine and maximize safe power gains.
