Vacum Lines? Where to?

[zeeboid]

Hey all.

Okay, first of all, I have a 2004 SRT engine in my 98 Neon. I hope to run it today, but need to figure out what to do with the Vacuum lines:



(note, the engine is actually in the car now)

The VERY TOP vacume line (comming off of the wastegate) is connected to a boost control solinoid, which when unswitched, goes to the intake manifold (through A "T" That also goes to the Megasquirt), and when switched, is a pressure dump.

Yep. Thats where i'm at. Now, as a turbo n00b, what do I do with all the other lines?

ok, lets make this simple...tear all your vacuum lines off, they are set up for a SRT4 computer, if you're using MS, start from scratch, first off get a vacuum block with nipples enough to run everything, you need 1 nipple for MS, 1 nipple for a 1:1 regulator(assuming you are using one) one nipple for a blow off valve, one nipple for the wastegate, so 4 auxilary nipples altogether, hook this vacuum block to a nipple on the intake manifold(or on the TB if you have one)...run one vacuum line(#1) directly to MS, run one vacuum line(#2) directly to your 1:1 regulator, the other 2 are trickier...first though cap off(or block with a bolt if they are threaded) any nipples on the turbo compressor housing...you dont need them, since the compressor housing really isnt the best source for a boost signal, thats why you have the vacuum block. the next vacuum line(#3) should run from nipple #3 to the boost control solenoid(or manual boost controller if you dont want to wire a solenoid into MS) and from the boost controller to the wastegate actuator...as far as the final vacuum line(#4), that will run to the BOV...the only BOVs i have used are single port though, so I'm not sure where the other port on the BOV is connected to(you could always block it off and convert to a true BOV)
