370cc Flow Rate:

The 370cc/min (35lb/hr) flow rate is ideal for mildly modified VQ30, RB25DET, and 300ZX builds targeting 250+ HP. The flow rate is measured at 43.5 PSI (3 bar) fuel pressure, which is the industry standard. This flow rate provides adequate headroom over stock injectors while maintaining good idle quality and drivability.

Side Feed Design:

These injectors feature a side feed design, which is required for specific Nissan applications including the VQ30DE, RB25DET, and certain 300ZX configurations. Side feed injectors mount differently than top feed injectors and are not interchangeable. Always verify your vehicle uses side feed injectors before ordering.

Flow-Matched to 1-2%:

All DeatschWerks injectors are flow-matched to within 1-2%, ensuring consistent fuel delivery across all cylinders. This precise matching is critical for smooth idle, optimal performance, and safe operation. Unmatched injectors can cause cylinder-to-cylinder variations that lead to rough running and potential engine damage.

High Impedance Design:

The high impedance design allows these injectors to work with factory ECUs without requiring resistor boxes or special wiring. This makes installation simpler and more reliable. The high impedance design also generates less heat than low impedance injectors.

Excellent Atomization:

DeatschWerks injectors deliver excellent fuel atomization, which means the fuel is broken into very fine droplets. This improves combustion efficiency, increases power, and can improve fuel economy when properly tuned. Better atomization also reduces emissions and provides smoother idle quality.

ECU Tuning Recommended:

While these injectors can work with factory ECU settings in some cases, ECU tuning is recommended to optimize the injector scaling and fuel maps for the new flow rate. This ensures optimal performance, drivability, and safe operation. Professional dyno tuning is recommended for best results.

Why DeatschWerks?

DeatschWerks has been engineering high-performance fuel system components since 2004. Their injectors are flow-matched to within 1-2% for consistent performance across all cylinders. Every DeatschWerks injector is tested and quality-assured before shipping, ensuring you receive a product that meets their strict quality standards.

Power Support Guide:

The 370cc injectors can support approximately:

• 6-Cylinder: 250-300 HP (at 80% duty cycle)
• Note: Actual power support depends on fuel pressure, duty cycle, and BSFC
• Recommendation: Size injectors for 80% duty cycle at maximum power

Perfect Pairing:

For maximum fuel system performance, pair these injectors with:

• High-flow fuel pump (255 lph or larger)
• Adjustable fuel pressure regulator
• Fuel rail upgrade for better distribution
• ECU tuning to optimize for new injector flow rate

Installation Tips:

• Use new O-rings and seals during installation
• Lubricate O-rings with clean engine oil before installation
• Ensure injectors are fully seated in fuel rail
• Check for fuel leaks before starting engine
• Set fuel pressure to 43.5 PSI (3 bar) for rated flow
• Get ECU tuning after installation for optimal performance

Perfect For:

• 1996-1999 Nissan I30 and Maxima VQ30DE builds
• RB25DET engine swaps and upgrades
• 300ZX fuel system upgrades
• Mildly modified builds targeting 250+ HP
• Anyone needing reliable side feed injectors

Perfect For: Nissan VQ30, RB25DET, and 300ZX owners seeking reliable fuel system upgrade with proven DeatschWerks quality and flow-matched precision.

Pro Tip: Verify your vehicle uses side feed injectors before ordering - these are not compatible with top feed fuel rails.

Flow-Matched: DeatschWerks injectors are flow-matched to within 1-2% for consistent performance across all cylinders.
