VGT - Variable Geometry Turbo
VGT's are being used in turbodiesels in Europe, and are becoming more and more common. I was just wondering if VGT technology can be used in gasoline engines? Does anyone have more info?

Looks like the only current non-diesel example is being using in the 911 Turbo. Seems the exhaust from regular gas engines is too hot for them.

Borg Warner has the only production units currently.
The BV43 turbocharger from Borg Warner is the only unit that the public can buy for a gasoline engine, but you still need to keep temps down below 1100degF.
The 997 Turbo's VTG turbo from Borg Warner doesn't have a BW part number, and can only be bought through a Porsche dealership.

Re: VGT - Variable Geometry Turbo (92TypeR)
WTF, does nobody know how to use the search funtion?
This topic has been beaten to death really
try seachign for VNT also (variable nozzle turbo)
The 89 Dodge Shelby Daytona was the first and really only affordable VGT turbo out there. It was only good for abou 250whp.
Like said, some deisels have it and the new porsche does, but the porsche ones are $5K EACH!!!!!!!
In a gasoline car, the vanes have a tendency to stick and then they don't operate correctly, causing over/under boost situations.
