Compatible Vehicles & Fitment

ZEX Nitrous Oxide Systems are engineered to integrate seamlessly with a wide range of vehicles, from modern EFI platforms to classic carbureted builds. Each kit is designed for straightforward installation and reliable performance across multiple engine configurations.

EFI Vehicles

ZEX EFI systems are compatible with:

  • Most factory and aftermarket fuel‑injected engines
  • Domestic and import performance platforms
  • Naturally aspirated and forced‑induction setups
  • Vehicles equipped with throttle‑position sensors (TPS‑based activation)

Carbureted Vehicles

ZEX carbureted kits fit:

  • Traditional V8 muscle cars
  • Street/strip builds
  • Classic carbureted trucks
  • Engines using square‑bore or spread‑bore carburetors

Engine Types Supported

  • 4‑cylinder, 6‑cylinder, and V8 engines
  • Single‑throttle‑body and multi‑port EFI
  • Naturally aspirated, turbocharged, and supercharged applications
  • Stock, mildly modified, and fully built engines (shot size dependent)

Universal Fitment

Many ZEX components—such as bottles, brackets, solenoids, and accessories—are designed for universal installation across:

  • Cars
  • Trucks
  • Off‑road vehicles
  • Custom performance builds

Fitment Notes

  • Always match jetting to your engine’s power level and fuel system
  • Verify fuel pump capacity before selecting higher horsepower shots
  • Some vehicles may require additional accessories (window switch, purge kit, bottle heater, etc.) for optimal performance

Installation & Maintenance Considerations

Proper Installation for Optimal Performance

ZEX Nitrous Oxide Systems are engineered for straightforward installation, but correct setup is essential for safe and reliable power delivery. Always follow the kit‑specific instructions and verify all electrical connections, fuel lines, and activation points before first use.

Fuel System Requirements

  • Ensure your fuel pump and injectors (EFI) or carburetor (carbureted setups) can support the selected horsepower shot.
  • Upgrading to a higher‑flow pump or regulator may be required for larger jets.
  • Always confirm adequate fuel pressure under load.

Electrical & Activation Checks

  • Verify throttle‑position activation (TPS) for EFI systems.
  • Confirm all relays, switches, and safety devices are wired correctly.
  • Test activation circuits with the engine OFF before live testing.

Bottle Mounting & Routing

  • Mount the nitrous bottle at the recommended angle for proper siphon pickup.
  • Use high‑quality brackets and secure all lines away from heat sources and moving components.
  • Maintain clean, kink‑free routing for both nitrous and fuel lines.

Routine Maintenance

  • Inspect solenoids regularly for wear, contamination, or sticking.
  • Check all fittings and lines for leaks before each use.
  • Replace bottle seals and filters as needed to maintain system integrity.
  • Keep the nitrous bottle filled with high‑quality, uncontaminated N₂O.

Jetting & Tuning Adjustments

  • Match jet sizes to your engine’s power level and fuel system capacity.
  • Retard ignition timing as recommended for higher horsepower shots.
  • Monitor air‑fuel ratios during tuning to ensure safe operation.

Cold Weather & Bottle Pressure

  • Maintain proper bottle pressure (typically around 900–1,000 psi) for consistent performance.
  • Use a bottle heater when necessary to stabilize pressure in colder conditions.
  • Avoid overheating the bottle or exceeding recommended pressure limits.

Safety First

  • Always use a wide‑open‑throttle (WOT) activation method or TPS‑based activation.
  • Consider adding a window switch, purge kit, and fuel pressure safety switch for enhanced protection.
  • Never activate nitrous at low RPM or under heavy load without proper airflow.
