Variable Nozzle Turbo

Does anyone know if any of these companies make a Variable Nozzle T3/T04 Hybrid Turbo, VN T25, VN T28? If you don't knwo what a Variable Nozzle Turbo is, here's a quick summary from ths site : Some turbochargers are Variable Nozzle Turbos (VNT). This is an awesome idea whoever came up with the idea. Just to put it simply, there are blades on the inside of the turbine housing. When the turbo starts spooling they are closed which decreases the volume of the housing and allows the turbo to spool faster. When it has spooled and the turbine gets fast enough, the blades open up, increasing volume, and allowing more flow for more power.

hmmm..........i don't think VNT's are too common for cars anymore, that was kinda older technology.

but i do know they use them on diesel trucks.

the concept behind it is quite interesting. My thought on it is that it can make a bigger turbo spool up faster then it normally would and still retain the power it can produce. Am I right?

and you'd also just spin your wheels all day long with fast spool-up on a HIGH powered turbo...... just stick with the norm... and you'll have a hard enough time keeping up with that as it is... don't cheat yourself before you have to
