Fuel Injector Clinic 1650cc High-Z Fuel Injector Set (ish03-1650h) - Holley GM Composite Intake
Step up the fuel system on your Holley GM composite intake with the Fuel Injector Clinic 1650cc High-Z Fuel Injector Set. Part number ish03-1650h includes eight high-impedance injectors rated at 1650cc/min, or 160 lbs/hr, at 43.5 PSI and 180 lbs/hr, or 1900cc/min, at the OE 58 PSI fuel pressure. Designed for serious street and race combinations, these injectors combine substantial fuel delivery with excellent low-pulse-width control and idle characteristics, giving high-horsepower builds the capacity they need without sacrificing the drivability that matters away from wide-open throttle.
Fuel Injector Clinic's 1650cc injector uses a stainless alloy valve construction that provides broad fuel compatibility, including pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Each ish03-1650h set is precisely matched using FIC's proprietary Data Match Technology. Every injector is individually serial numbered, and its results are documented on the supplied Data Match Sheet, providing detailed flow-matching and latency information for accurate calibration. Plug-and-play GM ECU data is also available from Fuel Injector Clinic.

Fitment
Designed for Holley GM composite intake applications. Fitment is based on the intake, fuel rail, wiring, and fuel system configuration rather than a specific vehicle year, make, or model. If your combination uses aftermarket fuel rails or another unusual configuration, contact Beefcake Racing before ordering to verify proper injector fitment and connector requirements.
FAQs
What fuels can Fuel Injector Clinic 1650cc ish03-1650h injectors run?
The stainless alloy valve construction provides broad fuel compatibility. These injectors can be used with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels, making them a versatile choice for powerful street, strip, and dedicated race combinations.
Do the ish03-1650h injectors require a wiring connector change?
The correct electrical connection must be selected for your specific harness configuration. A solder-in pigtail solution can be used to replace the existing harness plugs, while compatible plug-and-play connection options can provide the required conversion without cutting or soldering. Contact Beefcake Racing if you are unsure which connection option your combination requires.
