WRX Air filter/Turbo/BCS Setup (Useful)

[Alpha_2nr]

Here's a diagram of the WRX's intake setup, w/ turbo, vacuum lines, and stock Boost Control solenoid (top right). Should prove useful for those looking to swap parts like turbo inlets, aftermarket MBC's etc.

Hi everyone,

I have a stock 02 WRX (with a dealer installed boost gauge that is working) which is currently over boosting, this happened once before when a vacuum line came loose... I just reconnected it and everything was ok.

When the car started over boosting again, I checked that line again and its not only loose its gone.

In the diagram above I have another "T" fitting in line 3, the "T" is missing a hose... it has 2 hoses at the moment one going to the "T" fitting between the wastegate and the turbo nipple and another going to the boost controller but I cant figure out where the 3rd hose was going... I cant find a dangling hose anywhere.

Thanks in advance
