Nissan RB 875cc/min Top Feed Direct Fit Fuel Injector Kit

Description

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).

 Note: We need to perform an extra modification to the injector to use these injectors with R32 RB20/RB25 factory injector plugs. This modification is not required to use RB26 injector plugs. We carry out this modification at no extra charge.  

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.

While these injectors provide a large flow rate for little cost, they do suffer with low pulse width characteristics. For injectors in this size range, we recommend using our 1000cc/min injector kit over this Siemens 875cc injector in all instances except where budget is top priority. The 1000cc/min injectors not only flow more, they also have much better spray pattern and low pulse width characteristics giving superior control at idle and low loads. 

 

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.

 

Note that while these injectors are physically a direct fit, ECU retuning will be required
