Hey guys. Ive got a problem thats put my build on a hold for a while and ive been putting in my search hours like a full time job. So if you can help me id appreciate it. I have a RB25det with a gt35 .68 hot, with a apexi standalone without a proper tune. I need new injectors, obviously to run with a proper tune to get more acceptable power, however I am confused as which injectors to buy or which will work for my current set up. I have a superpower fuel rail kit with oem rb26 injectors (370cc). I would like to be around 740-1000cc for conditioned and reliable power. I do not know if I need top feed to work for my rail or side feed? any Apercu is appreciated, thanx guys

not sure how to answer this. but the stock 25 injectors are side feeds and 26's are top. so if your wanting to use that fuel rail you will need top feed injectors high/low impedance i am unsure of. but you will also need a new fpr if you dont already have one. the nismo fpr wont work with a top feed rail.
