[Supras] VATN turbos in readily available patterns?

[Walker, Brian (Rich. Dist)]

Does anyone know if Variable area turbine nozzles are available with the
popular patterns (T4, etc) It's old technology that's finally starting
to show up more often (even in OEM use) and I thought prices might be
headed to a more reasonable range if infact these are available.

Just benchracing with the idea but it would be great to have a good
flowing setup that could also spool very quickly.
