Setting Up My Ebc? Rb25

[sly32]

hey guys,

thought aswell post this up,

I have a HKS boost controller, ive put a rb25 into my skyline and now im trying to figure where to hook everything up,

ive uploaded a document with the instructions to hook up this controller but, this controller uses 3 vacuums if that makes sense (you will see in diagram),

so it says 1 goes to plenum or just behind the throttle body (tell me which ever 1 is better)

2 goes to acuator on turbo,

and the 3 goes on the hot pipe of the intercooler piping, which is where my problem is, i dont have a vacuum line coming from my hot pipe or any intercooler pipe for that matter,

where should i put this line?

Thanks JV

no1 know at all? should i hook both lines to plenum?

Nah don't do it to the plenum, you want it as close to the turbo as possible. So id fork out some cash and get some one to weld in a nipple on the cooler pipe coming out from the turbo.

Im guessing its a stock turbo and therefore doesn't have a nipple on the compressor housing?

[sly32]

yeah man stock turbo, mmm damn thats annoying i have to say, who will do that? i mean i could maybe get the welders at work to do it, what about, drilling a whole into it and then somehow putting a copper nipple into it?

o and also, that line that says go behind the throttle body, there is a vacuum thing that sits just above the throttle body, put that 1 line there? and the other to hot pipe?

Cheers

Easiest one to use is the vacuum line that goes to the fuel pressure regulator to the left of the oil cap.

Actually i just remembered (sorry mine is all aftermarket/custom shit so i forget what it all looks like from factory) there is a little nipple on the black intercooler pipe that goes from the turbo to the side mount intercooler. It's the one the factory boost solenoid uses. Have a look and you will find it. Here's a quick pick (its late so bare with the crapness lol)

Hope that helps ya man.

EDIT: Unless you have custom pipework like me, therefore you wont have any nipple, which after reading your original post is most likely the case. So yeah you could drill a hole into the pipework, and use a brass fitting and try to either weld it in or something.
