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.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
