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 the internal wastegate actuator

Port (3): to pressure only source

EXTERNAL WASTEGATE CONNECTION

The first method of installation is a one port connection. If the desired boost level is not achieved i.e. boost level is too low, or not

controllable, it is recommended that the wastegate spring be changed to a spring which is closer to the desired boost pressure or to trial

a 2 port connection method.

There are 3 different 2 port connection methods that can be trialled to achieve different results. The 2 port method (1) can be used if

there is high exhaust manifold back pressure forcing the valve open. The 2 port method (2) allows the user to achieve the maximum

boost pressure their turbo system is capable of. If a wide range of boost pressures is desired i.e. 5 – 40 PSI, the 2 port method (3) with

a 4 port solenoid (sold separately – TS-0301-2003) might be needed.

A single solenoid can be used to control twin wastegates in a twin turbo setup but it is recommended that twin solenoids are used in

twin turbo setups to reduce the length of the pressure hoses to aid in control and response of the wastegates.
