Ok, so I have a problem and can't seem to fix it. I have attempted to use an OBX fuel rail with my s13 greddy intake manifold. I have made my own mounting brackets and spacers but can't seem to get the rail to make a good enough seal on the ID2000.

So, has anyone had any good success with the Radium Engineering top feed fuel rail on the greddy intake manifold? Did you have to modify anything to get it to fit, or have any other problems, etc.?

Or, if you have any other advice about another fuel rail.

Thanks

No modification needed. Just be cautious when installing as you're messing with your injectors and could easily damage them from mishandling.
Mine went in without a hitch!

also what part number are the id2000s? for the radium rail they must be 14mm top and 14mm bottom orings if I can somehow miraculously remember exact sizes without googling it for you

I don't know the part number but I have the 11 and 14mm top hats. I would have to double check the bottoms. Thanks for the reply because my car is all finished except for the leaky fuel rail.

Just to clarify for everyone, the Radium Fuel Rail is a direct bolt on for greddy intake manifolds. I have a knock off manifold (version 1 style) and it bolts up with any sort of modification necessary. Just thought I would update this as to often threads ask questions but there is never a follow-up post with the outcome. Here are a couple of pictures for reference.

The issue with pencil style injectors is sealing them in the manifold. You didn't need to buy the rail but for the $60 + shipping they want just for the fucking seats you're probably better off buying the whole thing anyway.

slow92 · 04-14-2016, 02:02 PM

For me, the whole thing was leaking. I could not get a good seal between the top of the injector and the fuel rail or the injector and the intake manifold. I know this rail is pretty expensive and does not coincide with most 240 owners, but you get what you pay for. I had to fab up a few brackets for the HKS style fuel rail because the mounting points did not match up with the freddy intake manifold. So, I would rather spend more money and get a complete direct bolt on kit than mess around with making my own brackets and spacers to make a HKS style fuel rail bolt on. Plus the radium fuel rail looks really nice.

That s13.4 cover... nice top mount setup too

Hammered paint?

Kylepaschke · 04-14-2016, 02:58 PM

Also- Where did you get the little tiny rubber spacers underneath the bracket? (In between rail bracket and intake manifold? Mine seems to fit just fine as is, but i'd like some bushings like that. Did you just happen to find some?

It is a hammered finish powder coat. The rubber spacers were oem from my original s13 inake manifold where the fuel rail mounted.
