So to say i'm not the most car cluey person around would be an understatement.

Just trying to add a manual boost controller/tee (GFB atomic thingo)

I understand it has to go imbetween the actuator but every other setup i've seen in threads/guides is different so i'm not keen on cutting and putting stuff in until i know 100%.

Bunch of pictures i took to help people out.

From what i've read that's my understanding, do i block the 3rd output of the current T that is there that goes from the canister thing to the TB and the actuator, use the actuator part and find a hot side output that's not the throttle body?

Use the actuator part of the below and find a hot side source that isn't the throttle body? Do i block the 3rd part of the current T?

Photos are not helping me. Is your RB20DET stock or has it had an electronic boost controller fitted? If its stock there should be a line going from a boost source to the actuator. Start at the actuator and work backwards to check. You will not be able to get less than 10psi in this case but you can get more. Cut that line and insert your manual boost T. The bleed or vent usually goes back into the intake via the bov return pipe but as you probably won't have any fittings you will have to improvise.

RB20s have a VERY short hose running from the fitting on the comp housing to the wastegate actuator. That hose is about 3" long.

That is the boost source at one end and the boost destination at the other. All boost controllers get fitted between those two points.

I reckon not being able to put on a boost controller is a waring sign that perhaps you shouldn't actually put one on.

Get someone who knows what they are doing (mate or workshop) to do it and set it up.

I appreciate your concern, but that is the exact reason i'm asking. It's not as clear cut as it was made out and from the ones i have looked at.

I understand i need a pressure hose from after the turbo to tell the boost tee how much pressure is going through and when to let the actuator open, the problem is none of the hoses i have found are of that nature, only ones i have go to the throttle body.

I'm asking this so I can potentially learn something and not have to pay for it.

The thing is, it is so easy that it isn't funny. There should never be any mention of "canister thing" and "TB" in discussion about where to connect to and from.

Apply brain, think about how it should work, then make it so.

Or, just google it. Been done 17 trillion times. And that's just this week.

Just thinking if it is a 25 turbo they don't have a port on the turbo for the actuator which i think removes the only port befor the throttle body and could be why the charcoal canister line has been tapped into, not the wright way to do it but could explain the trouble. Happy to be wrong though.

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      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
