I want that extra air to leave with as little hassle as possible, but do not want a drone or super loud exhaust.

Correct me if I am wrong.
My understanding was that the variable vane just allowed the turbo to boost at much lower loads, that is spooled up early without sacrificing top end.

Are you planning a bigger turbo with variable vane?
How do you plan on controlling the variable vane? Isnt it electronically controlled by the motors engine management system (on the late models).

Is there a simple control system that can be put on the variable vane for the older motors?

Best have a decent inter-cooler.
