You're wondering what whp level can be achieved at 3200 RPM on your 1.9:A 1.9 @ 3200 RPM would be the same as a 1.6 @ 3800 RPMmy friend did dyno 166whp @ 3800 RPM so there you have your answer
Wouldn't mind if he "tapped in" though

One thing that many folks do not understand is that one of these engines in a vanagon is a VERY different experience than in a rabbit/golf/jetta. The vanagon weighing in at 4,000lbs+ means that off-boost performance from a (relatively) puny 1.9 can be irritating. Lag is fairly untollerable, especially at higher elevations where off-boost performance suffers more. The vanagon trans is also not overly robust. Often the goal with a vanagon install is decent power without lag, not lag with a big trans and neck popping bang... Having an appropriately sized and properly controlled VNT will always be able to simultaneously spool faster, flow better at high rpms and return better efficiency than any wastegated turbo install. The obvious downsides are cost and labor to install and control. It took a lot of time and effort to get my mechanical control to work properly and reliably. A VNT17 on a 1.9 will give several pounds of boost at idle if desired and will flow considerably better than the VW T3 or K24 at high rpms. I would not go smaller than the 17. I have the stock ALH VNT15 on my 1.6 and it is appropriately sized. I also have the Euro separate manifold version of the same turbo on one of my 1.9mTDIs and IMO it is slightly too small. I have an 1852v (one of the twins from a v10 touareg) to fit to an ALH but have not gotten to that project (and probably won't for some time). That may turn out to be an even more appropriately sized turbo for a 1.9 in a vanagon but it may also be laggier than the 17. I have not used the Holset so I can't comment on it's specific characteristics.

I agree. I didn't word my post very well. High torque is more damaging to the trans than the same HP at higher rpms. At the same time, in a vanagon I care a lot about performance from 1,000-3,000 rpms and none at all about performance above 4500 rpms. Turbo choice is definitely a balancing act.
A properly setup VNT turbo is much more of a tranny breaker than any wastegated turbo will ever be! My GTB2056VL hits HARD when I ask it for full boost (30psi) on my PD130. I've already stripped the inner spline once on one of the front driveshafts and it is the sturdy 02M 6-speed 4Motion setup!
The bigger turbo that I have does not "hit" it is just smooth power the entire way. The only hit is the go pedal input. As smooth as you are with the go pedal is as smooth as it will be. Libby would know better as having it in your style ride, but the ALH I have has more of a "hit" than the holset in my 1.6. The vnt in my 01 goes from nothing, to a few pounds, to full boost 19psi ish at around 1,500. The holset goes from nothing, to a few lbs and no difference in power to 5lbs and feeling a little power, and it continues to grow boost as long as you are on the go pedal. If you are all out on the skinny pedal it will probably be making 18-20psi by 2,000rpm. The other holset you are getting without the ported shroud maybe faster than mine. The other thing is an 01 jetta is different than an 86 jetta and even more different than a vanagon. You may boost better since the van is heavy and you will always have a good amount of load against the engine. I think the smaller k14 has you thinking that the bigger turbo will be the same just more power. The k14 spools to full boost so fast it may seem like a "hit" to you. The larger turbo with the little bit of lag to full boost I bet will be just what you are hoping for.
