Summit Racing™ introduces its MAX-efi 500 Fuel Injector System, the most efficient way to convert your carbureted engine to premier EFI performance. These self-tuning throttle body units bolt directly to most 4-barrel manifolds; then, through their wideband oxygen sensor, the systems continually adjust fuel delivery to provide the optimum air/fuel ratio under all climate and altitude conditions. MAX-efi will support up to 500 hp, and the self-learning ECU allows for easy tuning. With safety in mind, these systems are also designed with a self-adjusting "limp home" mode to protect your engine if a sensor fails. In addition, they include a data-logging feature to track the system while it's running to ensure optimal performance. Other features of the Summit Racing™ MAX-efi 500 Fuel Injector Systems: * Powered by the most advanced self-learning technology available * 4-injector system is capable of supporting stock to 500 hp engines * High-flow aluminum throttle body with four 45mm diameter throttle bores * OE-quality wideband 02 sensor and TPS sensor included * Color touch screen hand-held controller * Billet aluminum anodized fuel rails * Compact external ECU for easy mounting * OE-style harness is clearly marked for easy installation and durability in extreme conditions * All sensors except the wideband 02 sensor and coolant temp sensor are integrated on the unit * Uses commonly available sensors for easy replacement if necessary * System uses a Temperature Manifold Absolute Pressure (TMAP) sensor instead of a MAP sensor, reading both air pressure and temperature * Fits square bore or spread bore intake manifolds. (Spread bore manifold requires an inexpensive plate to avoid leaks. See SUM-G1420) * Works with original carb-type distributor, factory-style throttle linkage, and most 4-barrel intake manifolds

Nick Williams Performance drive-by-wire throttle bodies are precision CNC-machined from billet aluminum to meet the demands for increased airflow on the drive-by-wire LSX and LTX performance engines. These throttle bodies require an aftermarket intake to fit the larger diameter throttle blade. They use a 6-pin late model connector that works with late model wiring harnesses. Tuning is required for installation; and the Nick Williams Performance drive-by-wire throttle bodies come complete with stepper motor and electronics installed. There is no need to disassemble your factory throttle body. Order the model designed for your vehicle and engine application.

DeatschWerks top-feed conversion fuel rails are designed to convert side-feed applications to top-feed. Many performance vehicles manufactured between 1991 and 2006 came from the factory with side-feed injectors. The benefit of the modern top-feed injectors is that they are easier to tune, less expensive, and flow more fuel than side-feed alternatives. These vehicle-specific fuel rails are sold in pairs. DW also offers upgrade conversion kits that come with injectors ranging from 750cc to 2200cc and are engineered as a system where injector, rails, and mounting hardware that work together to integrate flawlessly into the OE manifold and mounting points. Select the fuel rails or the upgrade conversion kit recommended for your application.
