I dont know where a hose goes

Post by **BlockHead** » Thu Jan 01, 2004 11:34 am

I installed the greddy intake plenum and when I was all said and done I had a coolant hose not hooked up to something, its the one coming off the idle control valve and I was say is about 3/4 inch in diameter. Any help would be appreciative.

Does anyone even know what I am talking about, its the big one that comes off the AAC

Can you take a picture of it? I don't know what it is, but I bet we can figure it out if we see a pic.

Sound like the intake air inlet, but shoot a pic or call us!!!

I'd be interested in this too as I'm in exactly the same position at the moment. I presume its this hose you're talking about ?

I'd also be interested to know what connects onto the 4 shiny outlets on the raised boss on the left hand side of the plenum in the picture. The GReddy manual I have is in Japanese and its not much help to be honest.

Mambastu thats the hose I am talking about, thanks for the pic

That is the hose that goes the the intake piping near the BOV. The brass fitting is the junction between the Valve and the hose off the l shaped intake pipr the goes over the coil packs.

I think that's the one anyway...

Here is a picture of the hose that should connect to the other end of. The end you see here connects to the inlet pipe near where the BOV is bolted on....if I am thinking of the right hose....

it has to get route back to the intake piping in fornt of the throttle body to allow the AIC/AAC to get air to idle speed. Mack

Thanks guys yall were very helpful, I think I got it, btw if I didnt have that hooked up would it cause it to not want to idle?

Definately, that allow some air to pass when the throttle is closed...without it, you wont get the meter air from the AFM into the engine and the air/fuel ratio will be way off.

And I'm curious.. the extra vacuum ports, are they extra or stock?

Post by **jbanach77** » Thu Jan 01, 2004 11:34 am

good thread!!!

Post by **mambastu** » Thu Jan 01, 2004 11:34 am

Great, thats one hose found

With the vacuum connections on the left hand side...

I presume the far left vaccum connection is for the fuel pressure regulator (?)

Not sure about the next two but presumably a take-off for a boost gauge and another one for the boost solenoid (?)

The far right takeoff is quite large so would this be the connection to the PCV valve in the R/H cam cover (?)

Maybe it's for the brake booster?

I've narrowed that down to another large bore connection on the top rear Jon

Maybe you could post a picture so we could help a little better, I was trying to understand the difference between the far left, far right, and top rear...I misunderstood...sorry. I guess it all depends on where you are standing...

Post by **PROJECTRB240SX** » Thu Jan 01, 2004 11:34 am

LEFT IS DRIVERSIDE, RIGHT IS PASSENGER SIDETOP IS NEAR REAR OF CAR, BOTTOM IS THE FRONT OF CARUPPER IS NEAR HOOD, LOWER IS NEAR GROUND

THIS IS STANDARD MECHANICAL TERMANOLOGY, USED BY EVERY MECHANIC I HAVE EVER WORKED WITH.

I work in a bodyshop, we use that all the time...but I wasnt sure if EVERYONE knows....

Looks like you have figured it out pretty good, the only thing is on mine(all stock) the boost solenoid runs off the intake pipes before the BOV, I am not sure that it will be the same there, it should be though.

Man, I wish I had cash laying around to buy one of those....you lucky bastards!!

I am just jealous, dont mind me.

Post by **mambastu** » Thu Jan 01, 2004 11:34 am

It looks like the standard turbos water return pipe goes into the back of the original plenum. Where have the guys that have fitted the GReddy plenums plumbed it in ?

Post by **jbanach77** » Thu Jan 01, 2004 11:34 am

does anyone have a pic of the manifold installed?

Post by **OutToWinPAHC** » Mon Dec 19, 2011 4:02 pm

Bump from the dead, I sit and wonder why does it idle on the boost side on not post maf pre turbo?

I dont know where a hose goes
