(Rb25det intake manifold)
I’m having a hell of a time trying to find the full part or part number of this coolant hardline

so far I was given these (Below) but they aren’t what I’m looking for and was told it’s the IAR or aac valve but that doesn’t seem to be it either. If someone could point me in the right direction it’d be greatly appreciated. Or if anyone has it for sale that’d be great too. I have recently purchased a greddy manifold and I can’t seem to find my old one to pull it off. 

  • (Front Heater Return / Water Pipe (under intake):
    • Primary part: 14053‑21U10 (front return pipe assembly for R33/R34 RB25DET)
    • Alternative listing: 14053‑21U00 (same pipe, sometimes interchangeably referenced)
  •  
  • Heater Feed Pipe:
    • Listed as 14075‑04U00 or feed-related variant 14053‑AG500)
  •

So....to find any R chassis part number, get your VIN (will be something like ER33-xxxxxx for you) and go to: https://www.amayama.com/en/genuine-catalogs/nissan and enter it.

From there you have access to a web version of Nissan's part system, FAST. It is a bit tricky to get used to, so maybe have a shot and post up what you think.  You can also search by general model but note in some cases your car might have different options so VIN is safest.  On diagram 211 I got 14075-75T16 for Connector, Water Hose

If I search for part 14053‑21U10 that you posted, that is also a water hose but not the one bolted to the plenum and 14075‑04U00 is the fitting where the water hose goes into the block.

Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun ....

...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up

      Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
