Upgrading your fuel injectors can significantly improve your Honda CR-V’s performance. This article focuses on 550cc fuel injectors and their compatibility with the B20Z2 engine, specifically addressing OBD2 requirements. We’ll cover key technical specifications, installation considerations, and compatible Honda models.
Technical Specifications of 550cc Fuel Injectors
These high-quality 550cc fuel injectors are designed to enhance fuel delivery and atomization:
- Flow Rate: 52lb/hr = 550 cc/min @ 43.5PSI (This signifies a substantial increase over stock injectors, allowing for more fuel delivery under higher engine loads.)
- Coil Resistance: 12.5 Ohms (High impedance, ensuring compatibility with your vehicle’s electrical system.)
- Connector Type: EV1/OBD1 (Adaptable to various Honda models, often requiring specific wiring clips for seamless integration. Free connectors/wiring clips are often available upon request from suppliers.)
- Design Features: Multi-hole disc nozzle for superior atomization, metal and composite plastic construction for durability, and a basket filter design at the inlet for fuel filtration.
Compatibility with Honda CR-V B20Z2 (OBD2)
The 1997-1998 Honda CR-V, equipped with the B20B4/B20Z2 engine, utilizes the OBD2 (On-Board Diagnostics II) system. This standardized system monitors emissions and engine performance. When upgrading to 550cc injectors on a B20Z2 engine, you’ll likely need specific wiring clips (often included with injector purchase) to ensure proper connection to the OBD2 harness.
Important Note: ECU tuning is essential when upgrading to larger injectors. The Engine Control Unit (ECU) needs to be recalibrated to account for the increased fuel flow, preventing issues like running rich and ensuring optimal performance. Without tuning, driveability problems and potential engine damage may occur.
Compatibility with Other Honda Models
These 550cc fuel injectors are compatible with a wide range of Honda models, including:
- Acura Integra: Various years (1986-2001) with B18A1, B18B1, and B18C engines. Certain years require specific wiring clips. Resistor box removal may be necessary for some models.
- Honda Accord: Various years (1988-2002) with 4-cylinder and 2.3L engines. Clip requirements vary by year and model. Resistor box removal may be necessary for some models.
- Honda Civic: Various years (1992-2000) with D15B7, D16Z6, and B16A2 engines. Clip requirements vary by year and model. Resistor box removal may be necessary for some models.
- Honda Civic Del Sol: Various years (1993-1997) with D15B7, D16Z6, and B16A engines. Clip requirements vary by year and model.
- Honda Prelude: Various years (1992-2001) with H22A4 engines. Clip requirements vary by year and model. Resistor box removal may be necessary for some models.
- Honda Odyssey: 1998 with 2.3L F23A7 engine. Requires specific clips.
Conclusion
Upgrading to 550cc fuel injectors can enhance the performance of your B20Z2-equipped Honda CR-V or other compatible Honda models. However, remember that ECU tuning is mandatory for proper functionality and to prevent engine damage. Always verify specific clip requirements for your exact year and model before installation. Contacting a qualified mechanic or tuning specialist is highly recommended for this upgrade.
