The image below is a view from the intake side of the turbocharger. The solenoid's function involves three hoses:
Hose #1 connects the boost solenoid to the turbocharger assembly.
Hose #2 connects the boost solenoid to the wastegate actuator.
Hose #3 connects the boost solenoid to the intake duct between the mass air flow sensor and the turbocharger.
Boost Solenoid
The boost solenoid is located just below the turbo inlet on the intake side. In the image below, the three hose connections as described above are labeled.
Solenoid is upside down compared
to actual mounting position.
Procedure
Disconnect hose #1 at the turbo and hose #2 at the wastegate actuator.
Cut off 1 foot of the 6' vacuum hose and cut it in half. Reconnect the two halves using the hose 'T' connector.
Attach the hose in place of the solenoid, connecting on end to the turbo and the other to the wastegate actuator.
Connect the third port of the 'T' connector to the rest of the vacuum hose and run it to a reachable area at the driver's seat.
Attach a valve at the end of the hose.
When adjusting the boost, open the valve only a very small amount at a time until the desired boost level is reached. Closing the valve completely returns the system to the standard boost level.
NOTE: If the boost does not increase much regardless of how much the valve is opened, then a larger valve may be needed.
NOTE: If you decide to remove the solenoid, make sure you plug up the hole in the intake tube where hose #3 connected to.
