(1) Install a 6Φhose fitting to both the [2] & [3] ports on the solenoid valve unit.
(2) As shown above, assemble valve unit with provided bracket and anti-vibration
isolators and install in the engine bay near the wastegate.
(3) Install the correct 6Φ hose fitting (sold separately) to wastegate dump (secondary)
port (usually located on the top of the wastegate.)
(4) Connect a 6Φhose between newly installed 6Φhose fitting and the [2] port on the
solenoid valve. Cut and adjust the hose length as needed.
(5) Connect another piece of 6Φhose from the [3] port on the solenoid valve unit to a
stable boost pressure source from the intake manifold or the turbocharger s
compressor charge pressure pipe. (*Be sure to have a boost pressure source
connecting the main lower wastegate port to a stable boost pressure source, as well
‒ see diagram).
* For twin turbo applications with twin external wastegates, place a Y connector
(sold separately) to split the connection from the [2] port of the solenoid valve unit
and connect to two upper dump (secondary) ports of the wastegates.
Important
・Don't install the product in any place where it will be subjected to direct sunlight or high temperatures.
・Make sure use cable ties on the hoses for secure connections.
・When installing hoses, be careful not to kink or twist the hoses.
・Audible clicking noises from valve unit may be heard from the solenoid. It is normal and is not a problem.
・Mount the valve unit with the provided anti-vibration isolators.
