This was connected between my blow off valve and intake manifold in the middle of 2 vacuum hoses - it looks like its all melted etc and i think it was causing problems with the blow off valve coz it was only working sometimes...

anyway ive connected a vaccum hose up without this and everything seems fine now - so just wanna know if anyone knows what it is? and do i need to have it connected for any reason???

thanks.

I got one in the same spot, it got HKS on it , I got a HKS BC so i guess it got something to do with that

this is a hks one too - it looks like its some sort of little filter but i cant see why u would need it... anyway i had it off all nite and drove a fair bit with no problems.. its all melted and f$cked anyway from being next to the heat shield. i wouldnt mind buying a new one if anyone knows where i can get it???

Its a filter. Commonly used on EBCs to prevent vapours from entering the unit and f*cking the map sensor up. The only reason I could see it being used on a BOV would be for the same purpose, keep vapours from going into the end and turning into liquid - possibly f**king the operation of it? Personally I dont think a BOV needs it, definately a plus for anything electronic thats getting a pressure signal though.. vapours are bad!

why would you have a 1 way valve on a bov hose? that would make it either stay permanently closed, or make it leak something shocking.

exactly, i doubt its a one way valve.... unless the BOV vaccum line was tapped into the brake vaccum line, and that came from the brake side, but i dont think thats what's happened here, if it is, put it back, quickly!

      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

      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.
