2D-mapped water-methanol injection kit with Dual Stage Technology for naturally aspirated petrol engines. The Stage 3 NA EFI DST brings water injection benefits to NA engines — reduced knock, cooler combustion, and up to 10–15% more power.

What's in the Box

• 300 PSI EPDM high-pressure pump (100% methanol-resistant, double-sealed)
• Stage 3 EFI controller with LCD display — 2D mapping via fuel injector pulse width
• 2× Hyper-Sonic™ injection nozzles (primary + power nozzle) with integrated 100-micron filters
• Dual Stage Technology (DST) included — independent control of both nozzles
• 3-litre reservoir (black) with pump mount
• Fluid level switch with LED warning light (red)
• OEM-grade weather-tight wiring harness (terminated connectors)
• Solenoid valve included (required for NA engines)
• All fittings, pressure lines, and mounting hardware
• Comprehensive installation manual

Key Features

• Injection type: Variable 2D-mapped (fuel injector pulse width based)
• Dual Stage Technology: Primary nozzle for moderate load, secondary nozzle at high RPM/load
• Engine compatibility: Naturally aspirated petrol engines — ideal for high-compression builds, NOS setups, and LPG/autogas conversions
• Power gains: Up to 10–15% — earlier ignition timing without knock

Who Is This For?

Naturally aspirated engines that run at the thermal edge — high-compression builds, cars running NOS, LPG conversions, or any NA engine losing power in hot conditions. Not for turbo/supercharged engines — those should use the turbo-specific Stage 1/Stage 2/Stage 3 kits.
