Idle Air Control Valve Help

[jet2nv]

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

ok any idea about replacing the plastic idle screw on the neo the head is all mangled, would love a metal idle adjust screw

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
