streeteg Posted September 19, 2007 Author Share Posted September 19, 2007 hahaha does it come stock on the manifold, the line or the master cyl? Cause I havent changed anything but the manifold--- ZUL8R--- did you have to add one when u installed? Quote Link to comment Share on other sites More sharing options...
Z U L8R Posted September 19, 2007 Share Posted September 19, 2007 no i'm still using the 30 year old original vacuum brake booster 1 way check valve >_< it's part of the car basically. if you look at your brake booster, and follow that hose towards the hood latch. right there is where the check valve is, kind of secured to the firewall, then the other end of the hose runs to the top bung on your greddy manifold. if you look at the picture in my sig, it's on the firewall right behind where my o2 sensor sticks out of the top of my downpipe. that's where it's located.

triple B Posted September 21, 2007 Share Posted September 21, 2007 i am glad somebody mentioned the check valve i would have blown the cap off my master cylinder Quote Link to comment Share on other sites More sharing options...
streeteg Posted September 21, 2007 Author Share Posted September 21, 2007 A few things about that tho... 1. I have the line going straight to the master cyl 2. it was like that on the stock manifold so boost was going into the cyl---prob not good. 3. I have 3/8 line coming off my intake maniofld and also going into the master cyl--- but the check valve you can get at pep boys is significantly smaller--- where can i get a bigger one?

Z U L8R Posted September 22, 2007 Share Posted September 22, 2007 not sure.....you can use the hose off a 240sx unless it's the goofy one that's built into the hose itself....i can't remember >_ Quote Link to comment Share on other sites More sharing options...
streeteg Posted September 22, 2007 Author Share Posted September 22, 2007 It looks like I had the hose off the 240! haha so I wasnt as beat as I thought I was.... however after I finished everything last night there were a few things that I was curious about... 1. A harness clip that doesnt go anywhere... 2. The size of the hose coming out of hte intake--- 3. Fuel rail position on the greddy.... Pics will follow once the rain lets up today.

streeteg Posted September 22, 2007 Author Share Posted September 22, 2007 Well here are the pictures. The first is the fuel rail----If I tighten the bolts all the way down it seems that the injector harness will rest against the runners on the intake....When i had it first tightened down I couldnt even connect the clips---so I had to loosen it and bring it back up--- did I have to bend the tabs? Run some spacers? or should I just go ahead and tighten it all the way down? The next is the blue clip coming out of the engine harness... I marked all the clips (or at least I thought I did so I am not sure where this one came from? Look familiar to anyone? I dont want to turn the car over with something important missing.... especially with the lack of a check engine light lol Quote Link to comment Share on other sites More sharing options...
Z U L8R Posted September 24, 2007 Share Posted September 24, 2007 the blue plug is for your idle air control valve air regulator valve, it's the goofy thing that's bolted to the bottom of the stock manifold. there are plastic washer/spacer's that sit inbetween the fuel rail and the manifold, you can use metal washers, just something to take up the gap.

streeteg Posted September 27, 2007 Author Share Posted September 27, 2007 how many plugs fit under there? I already have a brown and a purple plug hooked into the back of the mani? Quote Link to comment Share on other sites More sharing options...
streeteg Posted September 30, 2007 Author Share Posted September 30, 2007 nevermind! found it---- that is really tucked under there... Quote Link to comment Share on other sites More sharing options...
Ed260Z Posted March 22, 2010 Share Posted March 22, 2010 Check out this install. Still a bit lost as to the 3 of the 4 vac taps on the bottom of the intake, but very good write up. http://www.skylinesaustralia.com/forums/to-Greddy-style-Plenum-t181826.html Quote Link to comment Share on other sites More sharing options...
