Need Fuel Rail Bolt Spacing Information! Gtr/rb25 Neo

[n_D]

Howdy

I have a Neo rb25 with an aftermarket plenum.

Im trying to find an appropriate fuel rail, tried a R33 top mount and the mount spacing is too wide!

The plenum I have has the same spacing as the standard NEO fuel rail, about 370mm between bolt holes. I was wondering if someone could measure the spacing on a rb26, I believe it should be the same but want to make sure before I go purchase another rail.

BTW have a brand new black anodized proflow fuel rail for sale $170

Also how necessary are the little micron filters that came with the length adapters for ev14 injectors? Do they just press into the top of the top hat?

Those filters really help you avoid starting your collection of failed EV14s.

Those filters will also block quickly if you don't sort out a good inline filter for your fuel system.

What is the issue with the stock rail, and why the hell have you changed the plenum?

Motors in a S15 silvia, needed to minimize piping and car will be pushing a bit of power when its done I dont have the stock rail anymore.

Got engine bay tubbed and sprayed, looks a lot neater.

So those micron filters just push into the top of the length adapter?

Yep, I use a nylon hammer and gently tap them in.

I didnt use those filters :S is that a bad idea?
running e85 as you know.

[scotty nm35]

As long as you have a large stainless mesh filter of 30-40 micron or less inline, you shouldn't need those filters. They block easily as they are so fine, and they don't have a lot of surface area. The only injector blockages I have seen so far have been those small filters clogging.

If you changed them regularly they would be a great backup to your main filter.

yeh so gtr doesnt fit either ffs

[scotty nm35]

GTR what? Fuel rail?

Just put a Neo rail back on, why is it so hard?

[n_D]

Yeh i tried a rail to suit a rb26. I dont have the stock rail anymore, its also not the prettiest

Heres my build http://www.skylinesaustralia.com/forums/topic/436499-rb25-neo-silvia-s15/page-1

Im not a retard haha I just like things fitting properly, plazmaman makes a neo specific rail and in the process of getting measurements of it.

If all else fails ill just get something made up to fit the gtr rail, hole for the mount is only 5-10mm off
