Off Valve
The ST165 and ST185 did not come equipped
with an air bypass valve for turbo protection. Due to the lack of
spacing and customer support kits were never created for these
vehicles. Here is the information about the universal valves
available so that you may create your own system. If you are buying
a Blow Off Valve, regardless of brand, be sure to get the universal kit
unless otherwise specified. For more information about what a Blow
Off Valve is, visit the BOV FAQ

Valve Listing
A bypass valve will release turbo
pressure between shifts. The term "bypass" relates to the
idea that the turbo air is then rerouted back into the intake. These
valves are designed to be fully open in any amount of vacuum, so they can
only be routed back into the intake, otherwise stalling would occur.
It can be argued this is the "proper" way to release turbo
pressure so that no air is ever lost from the intake system. This is
also the same setup that the ST205 GT-four and Supra Turbos use.
Standard
bypass valve, great starter to preserve turbo life. Has a tendency
to hang open during part throttle. Known as a
"hoot". They range from $33-$45 retail depending on which
version you would like to use.
