4-Hole Side-Feed Fuel Injector 2.0L 3S-GTE

The Walbro 23250-74150 is a side-feed, high-impedance fuel injector featuring a 4-hole nozzle and Sumitomo port. Specifically designed for Toyota 2.0L 3S-GTE engines, this injector is also a direct replacement for part numbers 23209-74150 and 23250-74150. It operates at a standard fuel pressure of 43.5 PSI / 3 BAR, delivering a flow rate of approximately 540 cc/min or 51.4 lbs/hr at this pressure. The injector's design aims to ensure precise fuel delivery for optimal engine performance. This injector is characterized by its high impedance, which is a standard electrical characteristic for many modern fuel injection systems. The 4-hole nozzle design promotes better fuel atomization compared to single-hole designs, leading to more efficient combustion and potentially improved engine response. The use of a side-feed design is also a key factor in its application compatibility, particularly with specific intake manifold and fuel rail configurations. While the provided data primarily focuses on flow rates and electrical characteristics, it is crucial to ensure compatibility with your specific vehicle's fuel system and ECU. Always verify part numbers and specifications against your vehicle's service manual to guarantee correct fitment and performance. Consulting with a professional or referring to specialized forums can provide additional insight into specific tuning requirements or potential upgrades.
