Also this has 2 spots for vac hoses do they both go to the manifold ?

And this is a solenoid that is used to trigger (I think) the vacuum to the charcoal canister when the (factory) ECU determines that it is OK to do it.  So, no, both do not go to the manifold.  On the stocker, one would go to a vacuum source and the other snakes off towards the front of the car.

Is it for vac?

Yes, but not in the way that you're thinking.  That pipe is visible there, and on the other side of the timing cover.  On the inlet side, it is connected to the plenum.  On the other side it is connected to the suction port of the charcoal canister.  It provides the suck that purges the canister (and fuel tank) into the engine.

The solenoid valve you posted earlier is also connected to both the plenum and the charcoal canister.  It is the switch that makes the valve on the charcoal canister open.  There's no flow in that line, just a vacuum signal.

All the plenum vacuum you could ever want is available off the many vac ports they added down the back end of yoru new one.

Did you decide to put this plenum on without making notes on how the original setup was plumbed up?

I work shift work and every time I started pulling the standard stuff off I got called to work for 12 hour shifts so I lost track and that's been the problem ahha

It's not for gain it's perparing for top mount turbo setup coming soon

 

Ah yes, but I have a top mount neo and do not need this manifold :P

That said, you're in it, and it's on the car, so may as well finish it now.

Sorry, but that makes no sense.  There is more than one way I can read your question and none of them make sense.

1. Are you talking about the small hose on the barb on the intercooler return pipe just before the blue silicon joiner?  If so, that is not stock, it has been put there by somebody else, so it could be for anything.  It could be connected to that boost controller we see behind the PS reservoir.  It could be for a boost gauge.

2. Are you talking about the boost controller in the background?  If you are, one side (the input side) must come from the turbo outlet or intercooler hot pipe.  The other side goes to the wastegate actuator.

That one (the barb, near the blue joiner) is stock on a R34 neo, it does indeed go to the power steering. It's used for speed sensitive power steering (somehow) and disconnecting it does result in some VERY heavy steering.. as well as a boost leak).

It runs from the PS to the charge pipe. It doesn't run to the plenum, so it'll go back to somewhere on your intercooler piping. If this doesn't exist, well you can block the hose if you like heavy steering all the time, or get a fitting put on your charge pipes.

Yes the barb is factory on the 34s thank you glad you could understand haha

Thanks so don't delete it just put it back into the cooler pipes no problem thanks for explaining it to I wasn't sure what it was for

Nuh it's a power steering air control valve, it's only for bumping up idle when you turn the steering wheel. Mine's removed when I got a replacement pressure hose made up

Just block up the fitting that goes back to the plenum and the IC pipe

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
