Hey guys- New to the forum. I know this topic has been covered before and people are probably sick of trying to explain it. I just wanted to ask someone who has actually seen the Greddy intake manifold on an RB25det neo head. Please no guessing from threads you've read about on other forums. If you know for a FACT! Then please chime in. I know that the mani will bolt on to the head w/o any problems. My question is about the injectors. and the water lines. I know some mods will have to be done, I am about to order the mani from our local speed shop and they are reluctant to order it without confirmation. I'm sure a few other people on this forum would appreciate this question to be answered once and for all.Thanks all.

thanks. I appreciate the help.It looks like he just modded the fuel rail and was able to keep the stock injectors. My biggest worry was the bolting/mounting issue.

nah everything lines up just same as far as the head ports and studs go.. the only issue you will have is the fuel rail, stock throttle body will not work at all, (keep in mind when you omit stock throttle body you will have a CEL cause the traction control will be offline).and the last thing will be you IAC valve. the stock IAC valve doesnt line up at all. you can use a block off plate or you can can get ahold of a 1.6L sentra IAC valve from a 91-94 i believe.its the same identical part.

Thanks NEO, I appreciate the help. I have a feeling that I'm gonna be asking you for some more help in the future. I am gonna order the Greddy manifold in the next few days. I was hoping i could just make an adaptor plate for the IAC valve. But I will reserach just finding one that fits.

I'm pulling my motor and starting my build this weekend. Will post pics up soon!

dont think so. the neo has top feed njectors n the s1 and s2 have side feed, u might just be able to use the fuel rail and injectors but im not sure if they are the same size..
