FITTING AND MOUNTING INSTRUCTIONS
1.
Locate the factory boost control solenoid by following the hose from the VNT actuator (this can be
found from the factory service manual of your vehicle). This solenoid will usually have 3 hoses
connected to it - one for the VNT actuator, one connected to the vacuum pump, and another vent
hose connected to the turbo intake.
2.
Disconnect the hoses from the factory solenoid one by one ensuring to mark where each hose came
from. Connect them to the manual boost controller according to the markings engraved on the body
of the unit (a diagram is supplied below for reference).
•
Connect the hose barb marked
“ T “
( Turbo ) to the turbochargers VNT actuator.
•
Connect the hose barb marked
“I”
( Intake ) to the turbochargers intake pipe after the air
filter.
•
Connect the hose bar marked
“V”
( Vacuum ) to the any vacuum source from the engine.
•
Connect the hose barb marked
“B”
( Boost ) to the turbo outlet or intercooler piping.
*Note:
this hose usually does not exist on factory VNT systems, but it is necessary to
connect it as this is how it references the actual boost pressure to control the vacuum that
moves the VNT vanes. It is recommended that this line is a dedicated boost reference line
and not to tee this hose off for any accessories.
3.
When routing all vacuum lines in engine bay ensure to keep them away from any heat source that
could potentially cause damage to the vacuum line. It is recommended to use a heat sleeving or a
heat shield over the top for protection. Ensure to secure any loose vacuum lines in the engine bay
from moving components.
4.
When mounting this manual boost controller in the engine bay it is recommended to use the
mounting hole provided in a convenient location. Ensure it is kept away from any heat source that
could damage the unit. If close to any heat source use a heat shield or heat protection material to
protect it.
