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.
Thanks for the info theman - at what RPM does your holset begin to boost?
It is a hard question. It starts to spool just off idle but only a pound or so then around 15 or 16 hundred it is almost 9 or 10 psi. It really depends on the load, pedal input, and gear you are in. Steep downhill with no load it won't spool up as much as downhill, etc. What I stated in the first sentence is a good average. 18-20 psi around 2,000 rpm is possible with enough fuel in my setup.

HE211W compressor is capable of 15psi @ 2000rpm on a 1.9TD, and spooling it up to 27psi (possible from 2700rpm to 6000rpm if pump allows you to) you would be at 200 crank HP @ 5000 rpm
In real life it's not that far of from following the surge line pretty good and turbine flows at least enough for 190 crank HP, a very good match for a 1.9 IDI, even at lower boost levels

the other thing I forgot until I see this map again is even if you are not in the center island, this turbo stays very efficient

These turbos seem like the best Waste gate turbo option for the aaz and ahu/1z and 1.6.

Is there a manifold readily available that has a t25 footprint?
Or is it commonplace to use and adapter plate?
This turbo seems like it will foot the bill for my power goals.
Thanks for the info. Sorry if this post is considered hijacking the thread.

Not all all
If it helps you out - go for it. There's plenty of info here for everyone

Dirt cheap T25 manifold for golf/jetta mk1 and mk2 here: http://www.tanskyshop.com/vw-8v-cast-turbo-manifold-t3t25-tk-em02_p4475.html remember to specify T25 otherwise you get a T3 one. Cast isn't perfect so be prepared to port it.
Alcaid, any idea what the ports look like and is there enough meat to make them "D" shaped? I'm assuming this manifold is for a 1.6?

Oops - got my intake and exhaust confused. Time for another rum

So, this manifold would be a perfect fit for the new turbo and a 1.9 or just a 1.6?
Fits both but not sure it does in a Vanagon

Thanks everyone for all the feedback and for putting up with my sometimes silly questions.
I've sent the funds to Alcaid for the Holset HE211W/HE200WG. I'll stick with my stock manifold for now and will build an adapter for it. The T25 manifold option is tempting but as was mentioned, my mount bar and other bits might be in the way.
Now I just need to design/build a new intake. Not sure if I should wait till I get the turbo bolted on or not but it will be at least three weeks before it arrives and I could have the intake built by then.
I'll keep you posted.

What type of intake are thinking of going with?
