1650cc Honda / Acura B‑Series, D‑Series, H‑Series Fuel Injectors

The SouthBay 1650cc Bosch‑based fuel injector is engineered for serious Honda/Acura builds that demand precise fueling, rock‑solid reliability, and compatibility with today’s most aggressive fuels. Designed specifically for B‑Series, D‑Series, and H‑Series applications, this injector delivers exceptional control from idle to full boost.

Performance Highlights

• 1650cc/min flow rate — supports high‑boost turbo, supercharged, and high‑RPM all‑motor setups

• Bosch EV14 technology — industry‑leading response time, atomization, and consistency

• Precise fuel control for stable AFR, crisp throttle response, and predictable tuning

• Flow‑matched for balanced cylinder‑to‑cylinder fueling

• Stainless‑steel internals — fully compatible with E85, ethanol blends, and oxygenated race fuels

• • High‑impedance design — no resistor box required

  • Ideal for heavily modified engines requiring large fuel volume

  •  

  Fitment

  Engineered for Honda/Acura platforms using:

  • B‑Series: B16, B18, B20

  • D‑Series engines

  • H‑Series: H22, H23

  Perfect for street, strip, or full race applications.

• Why These Injectors Stand Out

  These injectors maintain accurate and consistent fuel delivery, which is critical for high‑output builds. Whether you’re running big boost, high compression, or advanced fuels, the 1650cc set provides the stability tuners rely on to extract maximum power safely.

  Recommended Use

  • Turbocharged or supercharged builds

  • High‑horsepower all‑motor setups

  • E85 or oxygenated race fuel applications

  • Engines requiring large, stable fuel volume
