This Dry EFI kit delivers nitrous via a single nozzle and relies on the engine management system to introduce nitrous-enriched fuel. It’s compatible with EFI diesel engines that can accommodate external fueling strategies and nitrous enrichment through injectors. The kit includes jets covering a range of HP increments and supports upgrades as you tune for higher performance in a controlled, fuel-lean safe manner.

Buying Guide

  • Engine compatibility: Confirm your diesel engine type (common rail vs. VE/HP) and whether the kit requires a specific management system or ECU tuning sequence.
  • Booster strategy: Choose between single-nozzle, EFI-based, or dual-stage systems based on desired power curve, control, and install complexity.
  • Bottle size and pressure: Larger bottles (e.g., 10 lb) offer longer boost potential between fills; ensure your station and installation space accommodate the bottle geometry.
  • Power range and control: Progressive controllers help prevent lean conditions and protect the engine. For diesel builds that tow or haul, staged or progressive delivery improves drivability more than abrupt bursts.
  • Safety and plumbing: Inspect lines, fittings, and bottle valves for reliability. Diesel-specific installations benefit from robust mounting and vibration resistance.
  • Support and documentation: Look for kits with clear installation manuals, tuning guidance, and accessible customer support to address diesel-specific concerns.
  • Installation complexity and cost: Budget for ancillary components (fuel management, lines, brackets). Some kits assume a stock ECU or add-on controllers.

When evaluating options, consider your goals (daily driver vs. dedicated drag/track use), your willingness to integrate with engine management, and the level of refinement you need for safe, repeatable performance gains in diesel applications.
