dnatoli Posted September 27, 2012 Share Posted September 27, 2012 So if I use the greddy intake manifold for my rb25, do I need to get an aftermarket fuel rail and top feed injectors or what? And is the rb's injection system return or return less? Quote Link to comment Share on other sites More sharing options...
rayaapp2 Posted September 27, 2012 Share Posted September 27, 2012 hmm, The Greddy intake accepts the stock rails Ive seen. The Freddy does too! As far as what kind of fuel system, hopefully this is a case of you dont have the motor in front of you. All the RB25's Ive seen so far are return style. Ive seen motors up through 1999.

dnatoli Posted September 27, 2012 Author Share Posted September 27, 2012 I have the motor at home haha I'm at work right now. I know it's a series 2 rb25 but I can't remember what year exactly. Is the aftermarket fuel rails set up for returnless? Because that's what I would like to run Quote Link to comment Share on other sites More sharing options...
