Vacuum

[Trampisjr]

Can someone give me a diagram or tell me exactly how the vacum hoses hook up?
I turboed my lil 420a engine and the vacume is a pure mess and I have no idea the way it was or use to be since I droped the new moter in.

Can't help with the tech, however.

Just eliminate the vacuum lines. Heres what you need. A vacuum line from the fpr to the intake mani, from the brake booster to the intake mani, from the intake mani to the blow off valve, from the valve cover to the intake mani unless you have a catch can, from the turbo to the boost controller to the wastegate. everything else block off.

Hopefully these diagrams helps. If not, let me know and I'll see what else there is. These are for a 420a motor.
