Internal wastegates with 2 ports
Port (1): vents pressure from the solenoid.
Port (2): connect to one of the ports of the actuator
Port (3): to pressure only source
Block off unused port on the actuator with suitable blank
Single solenoid, twin parallel turbocharger hook up
(For straight configuration twin parallel turbocharger engines E.g. RB26DETT)
The e-Boost2 is capable of controlling twin internal wastegate turbochargers with a single solenoid.
This method is used when the turbochargers are mounted close to each other allowing the solenoid to be mounted close to both
actuators
Each solenoid port is connected as follows:
Port (1): vents pressure from the solenoid. Connect this hose to the intake side of the turbo, between the air cleaner and the inlet of the
turbocharger. Otherwise connect a short piece of the silicon hose and face the vent downwards to stop water or debris entering the
solenoid.
Port (2): to tee piece that feeds both actuators
Port (3): to pressure only source
Twin solenoid, twin parallel turbocharger hook up
(For V configuration twin parallel turbocharger engines E.g. V6, V8 etc)
The e-Boost2 is capable of controlling two solenoids for twin parallel turbocharger setups.
This method is used when there is a great distance between the wastegates. This allows the solenoids to be mounted close to the
wastegates to minimise the length of hose used and to maximise response
You will need a second solenoid for this method (TS-0301-3003)
Connect the grey wire from the e-Boost wiring loom to one of the wire from each solenoid.
Connect the brown wire from the e-Boost wiring loom to the remaining wire from each solenoid.
