Yeah. I know Garrett has some. Most of them are for diesels tho. I heard something that they can't take the heat from gasoline engines very well. I believe they are trying to work out the kinks but i wasn't sure if anybody has found one out there or made a small diesel work for them.
Ive been toying with the idea of setting one or two up on a gasser and see if there's any good gains or not.

VGT-Variable Geometry Turbo, VNT- Variable Nozzel Turbo. In simple form, allow the area around the turbine to increase or decrease in volume. When the turbine area decreases, it spins the turbine fast. This allows you to be spool up and give good boost very quickly at lower RMPs and then at cruising speed/when little boost is needed the volume around the turbine increases. So that you do not over spin the turbo or overboost your engine.
