Char Posted September 24, 2010 Share Posted September 24, 2010 had a look around but couldnt find enough info on this.. i have a greddy fwd facing plenum with 25det head, my tuner told me to look into using top feed injectors with top feed rail. my question is, what rail etc can i use, will a GTR fuel rail bolt on without modifying? or a hks (etc) brand suited for GTR? ... ebay rails? what about the clips etc? - im not worried about impedence as i have a microtech ecu. surely there are people running these.. if anyone has pics of top feed injectors in their rb25's thatd be awesome cheers Link to comment https://www.sau.com.au/forums/topic/338081-using-top-feed-injectors-in-rb25/ Share on other sites More sharing options...
NYTSKY Posted September 24, 2010 Share Posted September 24, 2010 You can get decent rails these days for around $200. If you are interested i have a set of top feed 1000cc injectors for sale $500 and they are yours.

Duncan Posted September 24, 2010 Share Posted September 24, 2010 just about to make the same change with my china ff plenum. fuel rails readily available eg ebay, and gtr injectors (440) are perfect for what I need. just need to change the injector plugs Link to comment https://www.sau.com.au/forums/topic/338081-using-top-feed-injectors-in-rb25/#findComment-5464843 Share on other sites More sharing options...
The Dan Posted September 24, 2010 Share Posted September 24, 2010 Yes the GTR fuel rails fit. You 'may' have to trim the spacer depending on the injector you use though.

Get EPIC Posted September 24, 2010 Share Posted September 24, 2010 So will a power fc run top feed on rb25? Link to comment https://www.sau.com.au/forums/topic/338081-using-top-feed-injectors-in-rb25/#findComment-5464871 Share on other sites More sharing options...
NYTSKY Posted September 24, 2010 Share Posted September 24, 2010 Top or side feed is just the style of injector. Link to comment https://www.sau.com.au/forums/topic/338081-using-top-feed-injectors-in-rb25/#findComment-5464876 Share on other sites More sharing options...
Adriano Posted September 24, 2010 Share Posted September 24, 2010 Yes, but you will need a resistor pack if running low impedence(ie GTR)injectors Link to comment https://www.sau.com.au/forums/topic/338081-using-top-feed-injectors-in-rb25/#findComment-5464879 Share on other sites More sharing options...

Yes, but you will need a resistor pack if running low impedence(ie GTR)injectors He doesn't need to with microtech.
