Hi, got some id1300s for my neo, but am having trouble getting them to fit. See pic (Plug base fouls on the manifold).

I was going to just grind a bit off the manifold but too much needs to be taken out.

Has anyone fit these type of injectors to a normal rb25 or rb25neo manifold.

On my old injectors the plug was more to the top.

They need spacers. These are pretty readily available. Those look like they are just the injector on its own. Pretty sure they need the smallest of the spacers, but top feed injectors in stock manifolds arent my forte

Scotty on here should be able to help you out. He will probably show up in this thread sooner or later

This is from a quick google search, bottom of the page. Click here

Cheers mate,

I have the height adapters for them to make them full length but they and most spacers go on the top of the injector?

Which doesn't help with the issue I'm having

Spoke to Scotty today, i may have to get him to make some spacers to go under the injector if i cant find anything else

Hmmmm I thought they made them for the bottom of the injector as well. But I may be wrong. They definently look shorter then my 1000cc's

I had a page with the pics of all the adapters etc attatched but cant find it. I may be talking complete rubbish though, Scott would know better then me

on a non neo you are required to fit an injector boss, which is just a metal spacer/o ring combo allowing the injector to be seated correctly.

Please don't go grinding anything.

That VPW fitting should work, I can get a hold of one and check it fits if you like, before you buy them, and work out what top spacer you will need too, as that needs to shortened by the same amount.

Thanks Scotty that would be great. Since I've organised the tuner for Friday it's all turned into a bit of a rush.. So I need to have them ordered early today.

If you've got one you can get hold of to check that would be awesome.

If I can't sort the top spacers out today I'll just space the rail up and sort that out after the tune

I just had the wholesaler flow test a 1650 shorty and you may have a problem with that idea. With that lower extension on the cone sprays out wide enough to hit the edge. It would have to be modified with a 45 degree chamfer, but this leaves the raw alloy exposed to the ethanol which is not a great long term option. It may get you by until you find a better solution though. Let me know if you want me to sort something out for you, I can probably make something up today and send the top and modified bottom extensions express.

Hey Scotty

I spoke to efi hardware, they have some adapters they Say won't affect the spray pattern, (they said the others do like you said)

and then I just run half height extensions on the top to make them full length

So hopefully that will work

*sorry short extensions on top

You don't want full height, you need 3/4 height for the neo.

Man, this is getting crazy, an adapter on each end, full length, the injectors will move around too much for my liking... You really don't want them popping out while driving, they need to be firm so make sure you keep the rail height down to minimum.

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
