Actuator or External Wastegate type

[swissboysupra]

I am a complete novice and newbie to cars... I have a 1990 Supra and want to install a Profec B spec 2 boost controller but don't even know if my turbo is an "actuator type" or "external wastegate type". My repair manual shows an actuator but also refers to a waste gate valve. I am already confused. Which type do I have?

A stock CT-26 has an actuator type wastegate. External wastegates are for big turbo applications with aftermarket manifolds.

Search tip - Search google images for wastegate actuator and external wastegate. You will see the obvious difference.
