Has anyone ever try using this kind of turbo application on a Z or any kind of automobile.. i'v look on the forum but didn't see anything

 

No

 

vnt? Variable nozzle turbine? I don't think so. they are pretty expensive IIRC....not really worth the extra coin, most likely.

Also, haven't these faded out of fashion once the advent of full ball bearing turbos hit the market?
