This item is for a set of six brand new Bosch 440cc/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 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.
These injectors have excellent characteristics at idle and low loads and flow enough to support over 300kW / 400 HP at the flywheel.
If 440cc/min isn’t large enough for you, we also have other direct fit options up to 1000cc/min injectors available.
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.
