Rb30 Questions

[RSFOURDayz]

Hi guys.. Just a couple of quick questions...

On the front of the throttle body of the RB30 down under where the intake pipe joins there is a small pipe connection that's for the Idle air when the throttle butterfly is closed. Is that meant to have a hose hooked up to it or not? If so, where too?

And, is the AAC valve supposed to have a spring in it? I read somewhere to be careful when pulling it apart so as to not loose the spring, mine definitely did not have a spring.

And help greatly appreciated.

For the first one, there should be a nipple on the intake pipe between the AFM and throttle body.

As for the spring no idea, but most have one

[RSFOURDayz]

This is a tiny nipple, like vacuum hose size and it's part of the throttle body, is that what you were thinking of?

Don't mean to sound like a tard here but isn't it RB20, RB25 and RB26 only, or are you referring to a stoked RB26 or something.

What is this I don't even?

no idea what this has to do with my questions...

I went and had a look at a mates and his has a hose coming off it but it just goes down by the engine mount so is still sucking in air.... i ended up blocking mine off till i figure out where its meant to go.

Do you still have the standard intake pipe?

[RSFOURDayz]

Yeah I do, the hard black plastic one. But it's nothing to do with that, this is on the actual throttle body itself.

[zebra]

Yeah just thinking there may be a nipple on it. But guess not. Maybe it is supposed to be open?

Hey mate... here's a pic of the throttle body showing what I am talking about, thanks.

Oh and as for the aac valve, i got one off a mate and they do have a spring.

[RSFOURDayz]

OK... thanks for all yr help Zebra, it's been confirmed that this pipe is supposed to have a hose on it going to the carbon filter.

hey i dont know if im meant to post questions not relating to the one above me, but it says "rb30 questions" and this is one!

on my rb30 the fan is constantly running even with revs so i can never ever hear what the engine sounds like, just one big loud fan is what im driving right now! is there a problem with it? should i just install a thermo fan? or is that just how it is?? cheers if anyone could help me!!

that pipe is for coolent to run through. to help the thottlebody warm up quicker or not freeze during winter... i think

get a gregorys (or similar) workshop manual and it will show you where these hoses go . . .as for the viscous hub, dont f#@k around with a secondhand (high mileage) unit, get a new one
