Paul was looking at the switchblade turbos from blaylock.
A vnt (variable nozzle turbo)the better of the 2 (VGT, VNT) and VGT (variable geometery turbo) do things different to each other. The switchblade alters the a/r of the housing.

I'm still waiting, since the 4th of Nov for a UFI 18 turbo, might start looking elsewhere..
Yehp. They are good at at leaving you waiting.
Thanks guys. Was hoping that someone had done a turbo fit out of this kind but used positive pressure to actuate the vanes in the turbo instead of using vacuum like on modern diesel engines. Not to worry, i'll read up on some turbo threads on here as I'm looking at turboing mine soon.
