Look out HUGE breakthrough in turbo design..
Introducing the new model, Porsche will be presenting the world's first turbocharged gasoline engine with variable turbine geometry (VTG).
This technology featured in turbocharged diesels since the '90s ensures a significant improvement of engine flexibility and acceleration particularly at low engine speeds. So far, however, much higher exhaust gas temperature of up to 1000° C in comparison with the turbocharged diesel has always proved to be an insurmountable barrier.
But now Porsche has solved this problem in close cooperation with Borg Warner Turbo Systems by using high temperature-resistant materials from space technology wherever required.
Yep.... Pigs are about to form a V formation like ducks and fly south to cancun for the winter...
The new 911 will have a variable geomety turbine. They call it VTG..
It will be some time before we see it in aftermarket performance turbos...
JZ sells BW....
Someone already beat ya to it though:

I still think they will be as common place as variable valve timing once the bugs are worked out..
I'd like a turbine housing that could span from .4 to 1.2 or so....
There are more cars coming with them...

The company is also supplying the turbocharger for the world's first gasoline engine to use both direct injection and a turbocharger, the Audi 2.0- liter Turbo FSI. The engine offers excellent performance with moderate fuel consumption while meeting EU4 and ULEV 2 exhaust emissions regulations. The engine was recently introduced in the new Audi A3 Sportback, and is now available on the Audi A4, the Golf GTI and the Passat.
I could also see the GDI technology going on the LSX after they GM gets done playing with DOD... Only two major components are hurdles (small ones) a GDI head and a high pressure pump.
