Grams Performance 1600cc 240SX/ S13/ S14/ S15/ SR20/ G20 Top Feed 14mm INJECTOR KIT

When you're looking to get the most out of your performance engine, getting the fuel delivery just right is key. This kit from Grams Performance includes four 1600cc top-feed fuel injectors, designed to replace your stock injectors and provide a significant upgrade in fuel flow capacity. These injectors are crucial for engines that have been modified for higher performance, ensuring they receive the precise amount of fuel needed for optimal combustion.

What sets these injectors apart is their construction and testing. They feature stainless steel internals, making them compatible with a wide range of fuels, including oxygenated types and racing fuels. Each injector is individually balanced and then flow-tested and dynamically matched to within one percent of each other. This meticulous matching process results in unmatched cylinder-to-cylinder consistency, which is vital for smooth idle quality, responsive throttle input, and overall engine performance, even at very low fuel pulse widths. The solenoids are ultra-fast and precise, offering a linear response across various operating conditions and maintaining accuracy even at high fuel pressures and short pulse widths.

This kit comes with the injectors themselves, along with 14mm top adapters and DENSO lower cushion bottoms. Please note that a wire splice will be required for installation, and this kit is not CARB approved, meaning it cannot be shipped to California. If you're rebuilding your top end or pushing your SR20 engine beyond its factory limits, these injectors are a solid option for ensuring your fuel system can keep up.
