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.

Sounds cool; do you know the A/R of the VW T3 off the top of your head?
.36 vnt15 hotside is probably too small for 50 trim cold
.36 vnt15 hotside is probably too small for 50 trim cold
That's kind of what I was thinking as well; might be efficient, but that doesn't matter when you've got that big of a trim cold side hanging off there pushing that much air. 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?
The 17/22 hybrid will do 200+ whp and 320+ wtq all day long on a 1.9 ALH.....
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!

I don't know the ar of any vnt stuff and its not really comparable anyway cause they're different families of turbo. If what 8v says is true then it would work a vnt17 but I'd do the 22/17 first

I agree the only thing ***ty about it is the ancient turbine wheel. But otherwise in gas applications its said to be good for 230 crank hp
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.

after some searching, a k03 hotside is .36A/R, and i presume the turbine wheel is about as restricting as that of a t3.
but bear in mind you can get different stages of T3 wheels. if you find yourself at a limiting factor (after extensive dyno testing) you will be able to sacrifice a small amount of spool and go up on the stage of the turbine wheel. T3's come in stage 1 (stock) through 5 (more flow).
if it were me, and my goal was over 200 hp at the crank, i'd probably go with a stage 3 .36 a/r hotside, or if my goal is a daily driver id go .36 stage1
