Looking for a larger injector for your high powered RB25DET NEO engine? Up for auction is a set of six (6) NEW Siemens DEKA 650cc/min, high impedance(saturated) fuel injectors. These are genuine Siemens brand injectors with custom milled height adapters to make them a direct fit for the RB25DET NEO fuel rail and manifold. Supplied electrical connectors must be utilized for proper connector fitment. 

At stock fuel pressure(43.5psi) this set will support engines making up 580bhp. These will flow 740cc @ 4bar/58psi fuel pressure which makes them great for growing applications.

Despite the high flow rate, they are linear and controllable at low pulse widths and have been used in ULEV applications! This allows you to use a larger injector than normally possible without hurting idle and low speed driveability. Adding to the flexibility of application, these units are high-impedance; making them compatible with most ECUs, while delivering the most flow available in a High-Impedance injector.

These injectors are able to function at high fuel pressures and don’t exhibit the high fuel pressure handling problems found with many other high flow high-impedance injectors. This makes these injectors very well suited to turbocharged and supercharged applications that see high fuel system pressures.

Engine performance and running quality are enhanced through the optimized spray pattern. Unlike competitors “pencil stream” high flow injectors; these High Flow injectors utilize a multi-orifice tip providing a true 30 degree spray pattern for improved mixture preparation. This results in lower BSFC and better idle quality than many injectors with less flow.
