Stock (TA) Actuator Adapter to TE Compressor Housing
Actuators made for a Stock, or TA series, turbo will not bolt straight up to the TE turbos as the TE compressor housing is larger and the bolt spacing is different.
One can either modify/rig the actuator to fit, or one can use an adapter as shown below. These adapters are available from the turbo vendors. Simply, it is a compressor housing retainer from a TE turbo that has a couple of studs welded to it spaced for a TA actuator.
