Quick Question

[agentx]

hey guys, i know this has been covered a few times but I just can't seem to find the specific bit of info I'm after (i've gone through 3 pages of threads ...).

I'm in the process of connecting a boost controller (the blue T-piece one). I'm trying to figure out the vacuum line connections ... I've got the wastegate running a vacuum line from it to one of the vacuum lines (near the emission control box). I thought this was supposed to be connected to a compressed air side? (from what I've read?).

It's an after market turbo which doesn't have a nipple on it and neither does my stock inter cooler piping. Now the question is, from the actuator, I'll run a line to the controller ... and from there, do i HAVE to get a nipple screwed on to the cooler piping (charged air side) or can I connect that line to some other little nipple on the rb20 (one that's screwed shut or something?).

Thanks for the help!

just hook it up to the intake manifold, plenty of nipples on there

I heard somewhere that the vacuum line to the boost controller should be as short as possible? Anyway I went yesterday and had the cooler pipe from the turbo tapped and chucked the hose in there Thanks for answering though.

Electronic boost controller or manual?

If its electronic it will have both a vacuum and pressure line. From the turbo's nipple or taken from intercooler piping, one line goes to boost controller under bonnet and from the boost controller a line goes to the waste gate. Now for the vacuum line which goes to the controller in the car, it t's into the intake manifold which will have a vacuum line somewere to use.

Some electronic boost controllers may be different so dont quote me on this. Use it as a example.

It's manual
