Fuel Injector Clinic 2150cc High-Z Fuel Injector Set (ish03-2150h) - Holley GM Composite Intake
Feed a serious high-horsepower Holley GM combination with the massive fuel capacity and precise low-pulse-width control of the Fuel Injector Clinic 2150cc High-Z Fuel Injector Set. Part number ish03-2150h includes eight saturated, high-impedance injectors rated at 2150cc/min, or 200 lbs/hr, at 43.5 PSI and 240 lbs/hr, or 2500cc/min, at the OE 58 PSI fuel pressure. These are FIC's largest high-impedance injectors, delivering the fuel volume required by extreme performance builds while retaining the short pulse width control needed for responsive low-speed operation, idle, and part-throttle drivability.
Because controlling an injector this large requires more than raw flow capacity, Fuel Injector Clinic uses its proprietary Data Match Technology for dynamic flow matching of the ish03-2150h set. This process significantly improves the ECU's ability to control these injectors in the sub-2ms pulse width range commonly encountered during idle and part-throttle operation. Every injector is individually serial numbered, and its results are documented on the supplied Data Match Sheet with detailed flow-matching and latency information. FIC flow tests and rates the injectors at 43.5 PSI using CF-16B calibration fluid maintained at 90 degrees F, and plug-and-play GM ECU data is available from Fuel Injector Clinic for calibration support.

Important Fuel Compatibility and Care Information
DO NOT use the ish03-2150h injectors with Q16, VP Import, or other MTBE oxygenated fuels. The internal construction of the 2150cc injector includes a seal that can swell when exposed to MTBE. This swelling can significantly reduce injector flow, making these injectors unsuitable for MTBE oxygenated fuels. When using E85 or other alcohol-based fuels, follow Fuel Injector Clinic's injector care instructions because prolonged disuse while alcohol-based fuel remains in the injectors can create potential corrosion concerns.
Fitment
Designed for Holley GM composite intake applications. Fitment is based on the intake, fuel rail, wiring, and overall fuel system configuration rather than a specific vehicle year, make, or model. If your combination uses aftermarket fuel rails, a modified intake, or another unusual configuration, contact Beefcake Racing before ordering to verify proper injector fitment and connector requirements.
FAQs
Can Fuel Injector Clinic ish03-2150h injectors be used with Q16 or VP Import?
No. Do not use these 2150cc injectors with Q16, VP Import, or other MTBE oxygenated fuels. MTBE can cause an internal seal in the injector to swell, resulting in a significant reduction in injector flow. Owners using E85 or other alcohol-based fuels should also follow FIC's care instructions, especially when the vehicle will sit unused for an extended period.
How can a 2150cc injector still provide good idle and part-throttle control?
Fuel Injector Clinic uses Data Match Technology dynamic flow matching specifically to improve control of these extremely high-flow injectors. The process helps the ECU control the injectors in the sub-2ms pulse width range commonly used during idle and part-throttle operation. Combined with superior short pulse width control and detailed injector data, this allows the ish03-2150h to deliver massive fuel capacity while retaining the control needed for tuning and drivability.
Why Buy Fuel Injector Clinic Injectors From Beefcake Racing?
A 2150cc injector is built for a serious fuel system, making the correct injector configuration, fuel choice, wiring connection, and supporting components especially important. Beefcake Racing can help you determine whether the Fuel Injector Clinic ish03-2150h is the right choice for your Holley GM composite intake and performance goals.
