Unless you're running them just like factory, and someone else snaps a picture of a factory setup, it will just convolute the issue for you. The system is actually quite easy... the diagrams make it seem more complicated than it is.
I assume you have a TII set-up with a manual trans...
Off the port on your intake manifold (next to charge temp sensor) run the main vac line out. I have a vacuum block hooked up which is set up as follows:
=> Boost Gauge
V l => Purge Solenoid
A l => Wastegate Solenoid
C l => FPR
l => Baro-Read Solenoid
=> Vacuum in from Intake Manifold
This set-up allows you to run straight shots of vacuum to all the devices without tees or orifices. Everything will work fine.
If you aren't running the evap system, then you can disregard the line to the Purge Solenoid. Since the Evap system attaches to the throttle body nipple, I assume you have it disconnected, which is fine. If you're running the evap system, it will have a check valve in the main run back to the throttle body. It also tees off and connects downstream of the PCV
valve (another check valve in there) and dumps into the large intake port under the fuel rail.
Some other bits:
- MAP is connected, via bleed nipple, to Baro-read Solenoid.
- Brake Booster vacuum line is on back of intake and goes to booster.
- Booster will then have a small vac line to your HVAC system and possibly to cruise control (with a check valve) if you have that feature.
- Using the throttle body for your BOV is correct.
- The turbo oulet nipple can be connected to cruise control (with a check valve), or an MBC if you use one.
- Make sure wastegate actuator is connected to the solenoid correctly.
Finally... make sure your PCV
system is working correctly. Use a good PCV
valve - preferable a MOPAR unit, they're only a few dollars. Get the three-way PCV
grommet from a dealer if yours is missing. The three-way grommet attaches to the PCV
port on the valve cover. The PCV
valve mounts in the grommet and then feeds into the intake port below the fuel rail. The third opening in the grommet goes back to your airbox port or a catch can if you run one.
If you do all of this with fresh vac lines, and your car still isn't right, you can safely rule out the vac AND PCV
systems. I'll take pics of mine later this weekend for you if you still need help. I have my top end apart for some work right now...
