I'm currently working on replacing all the vac hoses in my car. I'm using the Simiplified diagram found at Turborx7.com. I have no idea where the Vac that comes out of the Top Side Turbo Y-Pipe and used to go to the Pressure Chamber goes in said diagram. Does anyone know? In the diagram below is yellow and I've put an arrow to point to it.

Help please!!!

 

Just follow the colors. By the diagram it goes into the top nipple on the LIM which then goes to the pressure chamber.

 

No, not that one - that's the one coming out of the Charge Relief Value. I'm talking about the one coming from the top nipple on the Y-Pipe.

He's correct.

 

There are 4 nipples there, the diagram only shows three on one side, and the top one on the other side matches the color of the one on the Y-pipe. The first poster is right.

 

It goes direct to the pressure camber with standard routing, but in the simplified setup it makes use of the top through fitting on the LIM which leads to the pressure camber on the other side..

 

Oh okay, I understand! Thanks!



Another few questions:



AWS:

Since this is removed (lack of solenoid valve. Can I remove the hard pipe that feeds the valve and cap both the intake and the solenoid valve location without any ill effect? Basically the locations that I’m pointing at in the picture below.






EGR:
I have the EGR Valve, and it’s disabled – by that I mean that the input track (Light blue in the picture below) is capped off (I didn’t do it, I just noticed it). So the question is, can I remove the entire valve and switch and cap the out put track (light red) with again no ill effect?





Secondary Air Injection Pipe:
Can I take the pipe completely out and cap it off at the block with no ill effect?




By the way I’m using a PFC.

 

Shameless bump...

Again I know I can disable them, but does removing this stuff completely have any ill effects? Has anyone tried?

Thanks,

yes you can remove all of that crap. Thats mostly emissions that you dont need. Im assuming you dont need emissions. If you dont yes you can get rid of them. That is why they make the block off plates for that stuff at Gotham racing. And just to reassure you, that line used in the diagram used to go to the pressure chamber. but now the chamber is used for a vac source to the solenoid. So in other words cap the nipple on the Y pipe.
