Nodalmighty Posted May 27, 2010 Share Posted May 27, 2010 As above, I need an IACV VSV as mine has died. If you have one spare, please let me know. Ta. Is the actual motor body the same as a 1UZ-FE or MK3 Supra? If it is I have at least one. They are over £300 from Mr T lol Alternatively, send me your old one and I'll test/repair it. Lyndon.

Dr_Doom Posted May 27, 2010 Share Posted May 27, 2010 The IACV VSV is around £80 new from Toyota. Paul Whiffin got me one recently The bigger vsv's (EBV and Wastgate VSV) are a lot more expensive. I went through a few second hand IACV VSV's but they were all a bit ropey. I think they just die with age. I'm guessing the engine heat makes the electrical contacts break up inside.

I'm hoping someone will be along with one soon. There are plenty of people running TTC that don't use them anymore. While I wait I might open it up and have a look to see what I can see.

HTH I was quoted nearly £400 from Mr T when I enquired about one for my Mk3 (Granted it was a long time ago). £80 makes buying a brand new one a no brainer really. We are talking about an Idle Air Control Valve Stepper Motor? They would make a really cool proportional boost control valve with appropriate mods. Lyndon.

Dr_Doom Posted May 27, 2010 Share Posted May 27, 2010 While I wait I might open it up and have a look to see what I can see. I opened mine up to try and fix it. You can clean the valve, magnet, spring etc but it think it's the electrical part (which is sealed) that breaks. Mine functioned fine off the car & tested with a multimeter, but when in the hot engine bay it just didn't work We are talking about an Idle Air Control Valve Stepper Motor? Nope. It's the Intake/Inlet Air Control Valve - Vacuum Switching Valve. It's part of the Sequential system. They're usually easily confused on here!

As Doom said above its just a little pneumatic solenoid valve. When you see it you can't believe it costs £80 Link to comment Share on other sites More sharing options...

Nodalmighty Posted May 27, 2010 Share Posted May 27, 2010 IACV is the generally recognised acronym for the idle valve. You got my hopes up there, I thought I could get a New Idle Stepper for £80 for a moment Bugger ! Lyndon. Link to comment Share on other sites More sharing options...
TLicense Posted May 27, 2010 Share Posted May 27, 2010 It's the OP who's confused things a little... asking for an IACV VSV which doesn't exist. IAC VSV = Inlet Air Control Vacum Sensing Valve IACV = Idle Air Control Valve Anyways, I may have one (IAC VSV), I'll have a check this weekend. If they're £80 new, how about £20 posted?

Sorry for the confusion, my mistake. I've only been looking into it today. Reading the guide here; http://www.mkivsupra.net/vbb/showthread.php?t=35926 and this one here; http://www.max-boost.co.uk/max-boost/supra/turbo.htm makes it sound like the 'Intake Air Control Valve (IACV)' is the actuator part of the assembly and that the Vacuum Switching Valve (VSV) is separate to control it. If you do have one, and its in good working order, £20 delivered sounds fair. I don't suppose you could check before the weekend could you?

Unfortunately it'll be tucked in Mr Ryan G's garage and he's away at the moment. As soon as I can get in touch with him I'll find out when I can pop around to dig it out. Just to be clear, which bit are you looking for? The VSV, or the actual valve assembly? I'm pretty sure I have both.... Link to comment Share on other sites More sharing options...
