This item is for a set of six brand new Siemens 875cc/min fuel injectors to suit a number of different Nissan RB engines.
Specially machined to accept 10.5mm top o-rings, 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 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 style injector plug. However, we do have direct fit options available for these engines.
