I've also considered a vnt-15 with a 50trim wheel and compressor. That would be quite nice. Otherwise you can order an off the shelf turbo metics 50trim T3 and get it with a stage1-5 .36 or .48 hot side.
.36 vnt15 hotside is probably too small for 50 trim cold

That would make the turbine the limiting factor. What would avnt15's A/R be anyway?What about a vnt17? They're big enough to hybrid with a vnt22 cold side, you think it would handle a 50 trim? IF not, than would a 45 trim compressor be better on the 15?
i doubt the .36 hotside is that limiting. the 1.8t k03 hotside has got to be about that size or smaller, and it pushes 180hp at 7k+ rpm with 5v per cyl!
The vnt15 and vnt17 have the exact same hot side. The compressor size is different. The turbine shaft of the 17 is stronger and consequently heavier - vnt15 shaft is cut down between the journal bearings presumably to reduce inertia.
