i have the bost controller as above and ive noticed that if im fully fanging it (like we're talking fullthrottle top end of 4th and 5th on high boost, the little plastic plugs that come with it to block the one spare hole in the solenoid pop out and it starts overboosting, i even tried siliconing in one of the plugs but now all of em are popped so i cant run high boost until i block this up, no screw came with the kit to block it up which is stupid and the tyhread seems to not be of standard thread types for that size screw, wtf can i do ?

no because when the plug is in i get no overboost, but when the plug pops off i get overboost, because it creates a leak in the solenoid, dunno wtf is wrong with your boost controller then dude coz if u have a leak u should be overboostin

I dont know, mine had always run with no problems without the little plug for the 3rd port.

i dont actually have it connected atm cause i have an adjustable actuator.

hey sorry to post this up so late.But ive had a problem with my boost ever since i got the above boost controller installed and i just found out that the vaccum + pressure lines swapped the wrong way (with the actu8or hose where the preassure should be and vice versa) so i was getting a suck reading where i should have been getting a push reading to the valve unit.HAS THIS HAPPEND TO ANYONE BEFORE AND WHAT DOES IT DO TO THE OVERALL PERFORMANCE OF IT BOOSTING ETC.?????

      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.
