    OK - so the STi would look the same minus the pre-cat in front of the turbo, right?

    Oh, and I guess it's missing the BOV recirc...

    Is there really only one upstream O2 sensor?

    Yup, it's a very vital sensor that the car uses while in closed loop operation.

    The only thing they don't show on that diagram they should is the recirc hose coming off the bypass valve.
    And they shouldn't really call it a BOV on there....
