1650cc FIC Nissan 240SX 11mm Setup Injector Set (High-Z)

Fuel Injector Clinic 1650cc Injector Set — Nissan 240SX 11mm Setup (is181-1650h)

A 1650cc high-impedance saturated ball-and-seat set on a Bosch core, configured for the 240SX 11mm application. High-Z means they run directly on a saturated driver — no resistor pack, no driver module.

Every set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered and the results come on a Data Match Sheet — the most complete flow matching and latency information available. Injectors are flow tested and rated at 43.5 psi (3 bar) at 90°F fuel temperature using CF-16B calibration fluid.

Superior short pulse width control and state-of-the-art matching make these easy to tune and give great drivability, so an engine fueled for four-figure power still idles and cruises properly. E85 compatible.

Fitment: Nissan 240SX with the 11mm injector setup — SR20DET, KA24, plus Silvia, Sentra, and 200SX applications.

Includes solder-in pigtails. The factory connector doesn't match, so you're either soldering the supplied pigtails in or sourcing adapters.

Roughly 850-900 hp capable on gasoline, closer to 600-650 on E85 at a sane duty cycle. If the build doesn't need that much fuel, a smaller set holds a cleaner idle.

Sold as a set of 4. Includes all O-rings needed for the factory application and the Data Match Sheet. Covered by Fuel Injector Clinic's lifetime warranty against manufacturing defects.

Verify your setup before ordering — this is the 11mm configuration. If the car has a top-feed conversion rail, injector height and O-ring size may differ, and FIC asks that you contact them before ordering for aftermarket setups.
