wtf is this piece.

[nissanguy13]

I was going through my boxes of parts and came across this. I remember taking it off my sr redtop beforing installing it, but i dont remember why, or what it is, or does. If someone recognizes this part can you let me know. I thought someone told me it was for emissions? and since it wont pass smog anyways i took it off.

factory blow off valve???? I'll run that part number at work and see if it brings something up.

[nissanguy13]

thanks. I tried to google it and went to kragen and other part store sites but couldnt find anything

[SiI40sx]

I know it has something to do with emissions

[~4N~]

It looks like the part that the black box is mounted to on the KA, it might be something similar, especially if it has to do with emissions.

EGR for sr20det. Sits on the side of the head next to the OEM catch can, and connects to the AIV by a metal hose.

thanks for the info guys. the engine shouldnt act any differently without it should it?

[georgesal]

no i take that ugly thing off on all the swaps i've dont

[Dream240]

That thing looks a hell of alot like the PCV setup attached to the driver's strut tower on the KADE, minus the resonator of course.

Definitely emissions related though.

[SoSideways]

That IS the AIV valve.

If you look at where all the hoses connects to from that thing, you'll see that it draws fresh air directly from the airbox, and from there it shoots it directly into the O2 housing, where we all have a plug there now.

shouldnt cause any problems to run without it. just remember to plug up the hole on your turbo extension.

[blu808]

You ditch that thing.


You need to plug up the hole in your turbo elbow as well.


Woot

[grnappletree14]

what do u plug it with

[Tenchuu]

it's a bomb. get rid of it quick!

[nrg]

just cut it off and leave 1/2" of the metal piping on, then just fold it over and hammer it shut. it should be good enough to not cause a problem. Or just do the nickle coin and jbweld thing (there's a thread somewhere). or get it welded.

Ken youre just mad cause youre back to a stock 240, lol.

thanks guys for all the info. i remember why i took it off, i put a megan racing elbow on.

[WILDACEX187]

the sr will run better without it. and u're saving weight too :D

[blu808]

Weld that shit mang.

[SoSideways]

Or use a nickel to block off the hole, then tighten the fitting back onto the nickel, and cut off the tube. It looks like ass but it works :)

[nissanguy13]

thanks for all the info. I took my stock turbo elbow off and put a megan racing one on when I swapped engines. I knew I took it off for a reason, but its been a while so i couldnt picture where I pulled it off or why.

[Sileighty_85]

Its the EGR Valve Its for emissions so yeah dont worry about it

[slideways14]

exhaust gas recirculation valve

[blu808]

Its actually the aiv valve.

Not a EGR

The Air Idle Vlave? Like the AAC?

That sits on the intake plenum.

AIV stands for Air Induction Valve
