Fuel Injector Clinic 2150cc Fuel Injector Set for 240SX 11mm Setup - High Z (is181-2150h) - 1989-1998 Nissan 240SX S13 / S14
Take your 1989-1998 Nissan 240SX fuel system into serious high-horsepower territory with the Fuel Injector Clinic 2150cc High-Z Fuel Injector Set for 11mm setups. Designed for S13 and S14 performance applications that demand massive fuel delivery without giving up the injector control needed at idle and part throttle, this set includes four 2150cc saturated, high impedance ball and seat injectors. Despite their substantial flow capacity, these injectors are engineered for excellent short pulse width control, linearity, and repeatability, giving tuners the precision needed to manage a high-output 240SX across a broad operating range.
Because of the extreme flow rate of the 2150cc injector, Fuel Injector Clinic uses its proprietary Data Match Technology with dynamic flow matching to improve ECU control in the sub-2ms pulse width range commonly encountered during idle and part-throttle operation. Each injector is individually serial numbered, with detailed flow matching and latency information supplied on the included Data Match Sheet. The injectors are flow tested and rated at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid. PGTDEN4 solder-in pigtails and the O-rings required for the listed application are included. Every injector is covered against failure caused by defects in original manufacture by Fuel Injector Clinic's lifetime warranty.

Fuel Compatibility and Important MTBE Warning
CAUTION: Fuel Injector Clinic specifies that the internal construction of the 2150cc injector contains a seal that can swell when exposed to MTBE found in oxygenated fuels such as Q16 or VP Import. This swelling can significantly reduce injector flow. For this reason, the is181-2150h is not suitable for use with MTBE oxygenated fuels such as Q16 or VP Import.
When using E85 or other alcohol-based fuels, follow Fuel Injector Clinic's injector care instructions. Prolonged disuse while the injectors remain exposed to alcohol-based fuel can create potential corrosion issues, making proper care and storage especially important for vehicles that sit for extended periods.
240SX 11mm Setup and Installation
The Fuel Injector Clinic is181-2150h is specifically configured for Nissan 240SX applications using the 11mm injector setup. PGTDEN4 solder-in pigtails are included with the injector set for the required wiring connection.
Modified Nissan 240SX fuel systems can use different injector, O-ring, and fuel rail configurations. Fuel Injector Clinic also offers a separate 14mm version of its 2150cc 240SX injector set, so if your S13 or S14 uses an aftermarket fuel rail or another non-standard fuel system configuration, contact Beefcake Racing before ordering to confirm that the is181-2150h 11mm setup is correct for your combination.

FAQs
Can Fuel Injector Clinic is181-2150h injectors be used with Q16 or VP Import?
No. Fuel Injector Clinic specifically warns against using its 2150cc injector with MTBE oxygenated fuels such as Q16 and VP Import. MTBE can cause an internal seal to swell, significantly reducing injector flow. When using E85 or other alcohol-based fuels, Fuel Injector Clinic's care instructions should also be followed to help prevent potential corrosion during prolonged periods of disuse.
How can a 2150cc injector maintain good control at idle and part throttle?
Fuel Injector Clinic uses Data Match Technology with dynamic flow matching for its 2150cc injector sets. This improves the ECU's ability to control these extremely high-flow injectors in the sub-2ms pulse width range commonly encountered during idle and part-throttle operation, helping provide the short pulse width control and drivability required from a properly tuned performance setup.
