Ok...after about 3 years, I have finally gotten around to boosting my built KA. I have all my parts and will be installing everything next weekend with the help of a friend of mine. My question, (even after searching) is how do I run all my vacuum lines? And by how, I mean exactly what and where do I "t" into? I have a BB T28 (internally gated obviously) whose waste gate needs a line. Where do I run it from? I have a Synapse Engineering BOV, where do I run that from? And AEM TruBoost, where do I run that? LOL I just can't seem to get straight answers. If someone can snap specific pics for me, that would be awesome. I just need to see where people are running their vacuum lines from. Thanks in advance guys.

PS...after thinking about it, this probably should have gone in engine tech...sorry. :(

And if you would use that search button you could easily discover it has been covered many times previously. Dont be sorry just dont do it again. P.S. If you are stuggling on thing like that maybe you should have waited and did some research before starting such a project and doing such mods?:bigok:

If I "t" into the vacuum line going to the brake booster (before the check valve), what should I be running that to? The BOV, AEM TruBoost, or wastegate? And which ever one that goes to, how do I run the lines for the other 2? LOL

From what I've read, the BOV needs to be "t" into a vacuum line from the intake manifold. In the FSM, it shows there are 4 lines (2 of which are vacuum lines) that come up from underneath the throttle body and run along the front of the engine bay (above the radiator). 1 of the lines goes to PAIRC-solenoid, and the other goes to the canister. Can I use one of those 2 for the BOV? If so which one and where should I "t" into it?

Well you can use the brake booster solenoid if need to, just get a vacuum line block and slap it in there for all your vacuum line needs.

Something like this:

So I could just run a line to my BOV, wastegate and TruBoost using that?
