8) Select and locate the required wastegate spring or combination of inner and outer springs on the upper diaphragm spring
support. See spring information above for detail on wastegate spring identification and selection.
9) Ensure that the diaphragm is inside the diaphragm groove. The six holes on the outer ring of the wastegate diaphragm should
be in line with the 6 holes in the lower wastegate cap.
10) Slowly push the top cap down on the lower diaphragm housing in a vice or press. As the cap reaches the diaphragm, slowly
turn the cap left and right as you lower the cap to the lower diaphragm housing. Make sure that the convolution of the
diaphragm is not pinched between the top cap and the lower diaphragm housing. Refit the upper wastegate cap re-
using the M6 Socket head cap screws. Again you may find it helpful to use a press to hold down the cap with a press or a
clamp while tightening these screws. Tighten the M6 Socket head cap screws using a 5mm Allen Key and torque to 8 N-m

NOTES ON BOOST CONTROL HOOKUP
WARNING! Changing your connection method can cause a higher than expected increase in boost pressure. Turbosmart recommends
adjusting your boost controller back to its minimum setting and measuring the new minimum boost pressure achieved by the new setup
before increasing your boost again.
IMPORTANT! Refer to your boost controller instructions for most suitable connection method to an external wastegate.
Basic setup
If no boost controller is being used connect the boost pressure source to the “bottom” port as shown. Connect the Hyper-Gate “top” port
to the intake side of the turbo, between the air cleaner and the inlet on the front of the turbocharger. Otherwise connect a short piece of
the silicon hose and face the vent downwards to stop water or debris entering the top port.
Boost Tee setup
When using your Hyper-gate in conjunction with a Turbosmart Boost Tee, fit the controller between the boost pressure source and
“bottom” port as shown. Ensure the arrow on the Boost Tee is pointing in the direction illustrated. Connect the Hyper-Gate “top” port to
the intake side of the turbo, between the air cleaner and the inlet on the front of the turbocharger. Otherwise connect a short piece of the
silicon hose and face the vent downwards to stop water or debris entering the top port.
Refer to the instructions supplied with your Boost Tee for further detail if necessary.
