This item is for a set of six brand new Siemens 666cc/min fuel injectors to suit a number of different Nissan RB engines.
Specially machined to accept 10.5mm top o-rings to fit the factory R32 type fuel rail, these injectors are a drop-in replacement for all R32 Nissan Skyline twin cam engines engines (RB20DE, RB20DET, RB25DE, and RB26DETT).
These injectors will also be a direct fit for a twin cam RB30 built with a an RB26 or R32 RB25DE head.
These injectors will also be a direct fit for an RB26 from a R33 or R34 GTR, however they are not a direct fit for R33 or R34 RB25 engines. Please see our notes below for more information on R33/34 RB25s.
These are a high resistance injector, so they can be used with all after market ECU’s without the need to use ballast resistors. If using these on a RB26 GTR, the factory resistor pack should be removed and bypassed. As an option, we offer an R32-R34 RB26 GTR Injector Resistor Delete for this purpose. When purchased together with this RB injector kit, we offer the resistor delete at a special price – simply select the resistor delete option with these injectors at the top of this page.
These injectors have good characteristics at idle and low loads and flow enough to support over 600 HP at the flywheel.
These injectors are NOT a direct fit for R33 RB25DE and RB25DET engines. These particular Nissan RB engines use side feed injectors. However, we do have direct-fit side-feed injector upgrade options available. It is also possible to convert an R33 RB25 engine to top feed injectors when using a custom made front facing plenum.
These injectors are NOT a direct fit for R34 RB25DET Neo engines. These engines use shorter top feed injectors with a 14mm top seal and a Denso high tag style injector plug. However, we do have direct fit options available for these engines.
