Nissan R34 RB25DET Neo, R35 GTR, 350Z – 720cc/min Direct Fit Injector Kit


This item is for a set of six brand new Bosch EV14 720 cc/min fuel injectors to suit the following applications:


  • Nissan Skyline R34 GT-T RB25DET Neo (05/1998 – 08/2002)
  • Nissan Stagea C34 Series 2 RB25DET Neo (08/1998 – 03/2001)
  • Nissan GTR R35 VR38DETT (04/2009 -)
  • Nissan 350Z Z33 VQ35DE / VQ35HR  ( 12/2002 – 05/2009)
  • Nissan 370Z Z34 VQ37VHR, (05/2009 -)
  • Nissan Skyline (C)PV35 350GT VQ35DE  (02/2002 – 09/2007)
  • Nissan Skyline PV36 350GT VQ35HR (11/2006 – 12/2008)
  • Nissan Skyline KV36 370GT VQ37VHR (12/2008 -)


These are a direct-fit upgrade for many late model Nissan engines including the R34 RB25DET Neo, R35 GTR VR38DETT and 350Z & 370Z VQ series engines. Unlike earlier Nissan engines, these later engines use a 3/4 length injector with 14mm upper and lower O-rings and a Denso high tag injector plug. This makes this particular Bosch EV14 series injector one of the few direct fit injector upgrades for these engines and it is an added bonus that this injector also have very good characteristics at low pulse widths and an excellent spray pattern. They are also a high resistance injector, so they can be used with all after market ECU’s without the need to use ballast resistors.


These Bosch Ev14 720cc/min fuel injectors are supplied in their unmodified form as they comes from Bosch. They are also ethanol E85 (flex fuel) compatible!


As these are a higher flowing upgrade over the factory injector, ECU retuning (dyno tuning) will be required. If required, we can supply dead time vs voltage data for these injectors at a differential (base) fuel pressure of 3.0 Bar. 


These injectors have excellent characteristics at idle and low loads, but flow enough to make up to up to around 650-700HP at the flywheel on regular pump fuel.


These injectors are NOT a direct fit for R33 RB25DE and R33 RB25DET engines. These particular Nissan RB engines are factory fitted with 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 using an aftermarket fuel rail kit that we can supply with appropriate injectors.
