Hey guys I'm trying to find out what other cars or company makes this iacv assembly for the rb25det neo as I'd love to buy a generic brand rather then the hi priced Nissan one. Haven't had any luck does anyone know a cross reference part.

23781-AA500 is the Nissan oem

There are none. Pay for the OEM Nissan one. Plenty of places where they can be sourced at a cheaper rate rather than directly from Nissan.

For the record they are not what I would consider expensive but opinions differ. Do you know that you need an actual replacement IACV to begin with also?

As above

You can easily test the IACV by putting 12V accross the coil. You should feel the solenoid click. If that happens, then likely it is O.K. Mechanically they can be disassembled, cleaned (they clog up with carbon) and put back together. Your only issue might be if a seal gets wrecked/is wrecked, but even then a replacement O-ring wont cost the world

The actual solenoid is very similar to some Pulsar N14 GA16 ones .

They had two styles , one type actually fits the R34GTt housing . The N14 one uses the same male connector as the R33 RB25DET's and is probably the one to use with Neo manifold/IAC in R33s .

If you need to get the cold start side apart heat the housing/bung with a heat gun .

yes this is a good pointer here, and i might add clean it 10 times after you think you have cleaned it enough. i know its a little different but on my 26 i had a leak from the idle screw on my iacv and this caused it always to idle at 1200rpm. ive since removed and dont use one but yeah make sure you clean the piss out of it, i had success with brake cleaner and air.  cheers

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
