Rb25 idle control lines?

[Tyler126]

Hey guys, Im new to the import scene and bought a s14 about a year ago. Im almost done with my S1 rb25 swap, but when I got the engine I was way too excited and tore into it without paying attention to the vaccum lines... All I need to know now is where the 2 lines for the Idle Control sensor go? Please help me out, Thanks!

That should help you a lot. You using the Greddy IM, or stock? The AAC valve on the back of the IM only has two ports, one of them goes to the brake master, the other to your coldpipe before the throttle body I believe.

Yes that does help.. Im using JGY's intake, so same style as the greddy. There is a smaller port and a bigger one that pritty much t's off from it. I thought the line that runs to the master cylinder just runs off the back of the intake?

Also, where does the air regulator go in line?

Here's how I have my Greddy IM set up:

I realize that painting everything black against a chrome intake mani makes it hard to see lol. I think you're right about the brake booster, my bad. The AAC valve (IACV) connects to the air regulator on one side (small port), and the coldpipe before the throttle body on the other side (big port).

The other side of the air regulator goes to the intake mani plenum.

Ya thats what I was thinking... It must connect to the bottom of the intake after the air regulator to create vaccum. Anyone know forsure if this how it works? Or where the other vaccum lines go?

Thanks for the help GSXR! Helped alot!

Sweet, yeah I downloaded those pics separately from another forum. My question about the Greddy IM is where to connect a swirl pot now that you loose the top coolant nipple on the IM?

Don't feel like digging it up right now but there is thread on this subject over on NICO :x Should only be a page or 2 back.
