Nissan RB25 Fuel Upgrade Kit! 
 
Clean Injection 550 Series  Bosch ev14 550cc High Impedance Fuel injectors, Radium Engineering Top-feed fuel rail conversion kit (part number:20-0277) with -6AN end fittings, and Plug & Play fuel injector connector adapters. This kit is a direct fit for the Nissan Skyline R33 GTS-T RB25DET non neo engine with factory intake manifold, Greddy intake manifold, ISIS after-market intake manifold, or Greddy replica intake manifold.  Radium Fuel rail is anodized coated making it safe for use on alcohol base fuels including e85. Injectors will come with a set of 6 plug and play injector connectors which will allow the injectors to plug right into the factory injector harness. No cutting or soldering wires necessary. 
 
The radium fuel rail is also fitted with Radium fuel pulse damper. The opening and closing of fuel injectors creates pressure pulses in the fuel rail which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow injectors. Furthermore, a fuel pulse damper can help solve erratic lean air/fuel ratio spikes, commonly experienced as "stumbling", that are difficult to tune out.  
 
  The injectors are compatible with all known fuels including e85 and alcohol base fuels.  Every set of Injectors that leaves our shop is goes through extensive testing on industry leading ASNU Classic test equipment. Injectors are flow tested statically, dynamically, and tested at different fuel pressures ranging from 2 bar to 8 bar. They are then sealed and packed in balanced sets within 1 percent with tuning paperwork.  Injectors will come with flow sheet with full data specs including injector latency/dead time data to make tuning breeze. The injectors retains a consistent linear flow from 3bar to 8 bar fuel pressure. Very tuner friendly with fuel trimming down to 1ms.
