s14 greddy sr manifold

[icemhan_21]

hey guys i just got these s14 sr20 with greddy knock off intake plenum.. ive searched and looked around fsm and found nothing about these vacuum lines from the greddy manifold so if any of you guys running this similar manifold please help me.. in the pics i put numbers beside the ports so it will be easier to identify..

these two ports are located just below the throttle body..

these port is located beside the manifold itself

these two are located below the manifold

i know that number 7 connects to the brake booster and port 6 connect to port 8? i just want to verify..

i know my engine is dirty and im about to clean it soon..

the first two are not on the manifold they are on the throttle body. you can cap them or use them for BOV or vacuum/boost type accessories.

3 looks like the one that goes to the FPR?, but I cant tell?

4 or 5 one them should be related to your idle air system. the other, I have no idea

6 connects to 8

and 7 goes to the brake booster.

Its hard to tell with your pics so you should wait for a second opinion. I have never seen that manifold before

1 or 2 will go to your blow off valve. And I can't remember what the other one goes to... stupid brain think
