various questions about swapping to a non-egr intake mani

[lilj]

Ok basically I'm getting ready to do the vacuum lines and such to my n42 NON-EGR (this means no more emissions) intake manifold. I was dumb when taking everything apart and didn't label anything but wiring. So now I've had to take the time to go through and figure out what everything is and what it does (not such a bad thing in the end..). Anyway, my first major question is about the 'heater block,' a hose (1) runs out of the thermostat housing (A).. and runs into the throttle body inlet ( then another hose (2) runs out of the throttle body outlet © to a block of sorts with a sensor in it (it sits under the air regulator). Then it proceeds to another hose (I don't have a picture of the actual hose but you'll see what I'm talking about - 3). Then it runs around the head and down into a heater line that runs into the cabin.

 

Now the question is... Do I need this to have a heater? What sensor is this in picture #3? (its the purple arrow). I can't find the sensor in the damn haynes manual. All of the Z-car manuals seem to have everything but what my car has lol! =/

 

 

Ok, I know all the images, blah blah.. but I need to figure all of this out lol..

 

I'm keeping the stock throttle body until I can get a spacer from JSK. I know that there is a idle screw and what not on the side of the stock (W24) manifold.. I'm not really sure if I need to put it back on.. If so, how and where? On the n42 intake manifold there is no place to bolt it on.

 

Random Questions:

 

Is the Air Regulator actually needed? -Why?

What does the front of the Air Regulator hook into?

Where does the dizzy vacuum advance hook up? -Intake manifold?

 

I'm keeping the PCV system intact.. that is until my uncle comes up to Dallas in two weeks. Hes got a spare vacuum pump that he wants to hook up to it *GRIN* -- wonder if this is going to help me out much?

 

As I type this I'm starting to fall asleep (4:30am), so it just gets less understandable as I go.

 

Anyone whose done this intake mani swap and is willing to talk to me via aim or just post, please do. I hope to have to car running this next weekend (not likely, but I'd like to be as close as possible).

 

Thanks

Those two wires connected to the air regulator are not a "sensor". That is a heater built into the regulator that warms the air regulator up in addition to the warm water running through it. The wires send 12v to a coil to heat the spring inside and eventually close the opening once the engine warms up. I'm not sure if you can eliminate the air regulator, though. It gives the engine extra air to keep it from dieing until warming up and then it closes.

Disconnecting the heater hose from it would only seem to make it warm up slower and keep your engine idling high longer.

Ok cool, thanks for the info. I'm going to put everything back together pretty much stock. Minus most of the emissions that is =)

 

Almost back together, all I got left to get is injector bases, fuel rail, and some hose! =)

 

thanks again,
