Different Turbo Manifolds?

Ok, So I have seen the trapezoidal flange, the k14 style 3 bolt, and the ebay t3 flange. Are there any other flanges available on these exhaust manifolds? I just got a brand new Holset he221, but it has a t25 style flange on it. Anyone have any ideas on how to mount it up? I looked at adapters, but they were close to $150, not exactly what I wanted to do. Let me know if VW made a t25 flanged mani, or if you have a cheap way of mounting it.
Thanks,
Randy

K14s have a 3 bolt style? I thought that was the K03. Or are you refering to the mk3 K14?

I could be way off, I have no idea whats going on. I thought I read somewhere that VW made 3 different flanges, but again I really have no idea. I know some of you guys have loads of old turbos and manifolds laying around, someone post up a pic and the right name for each if you got them!

here is a K03 turbo off a 95 AAZ
This is the manifold used for K24s, T2s, T3s

my k14 also bolts up like the second picture (4 holes trapazoid)
i've never seen a T3 with a flange other than this:

My T3 is (trapezoidal... thought rectangular but I was thinking of the outlet!) as well... someone posted the K14 cad drawing but I can't find it at the moment.
Good cottage industry for someone with a CNC mill would be turbo adapters !!

Hmmmm....my Haas TM-2 mill should be shipping from CA this week. If someone has CAD files or is very detailed with measurements/diagram on the turbos & manifolds I may pursue this. I wish to be paid in Mk I or B4 performance parts. :wink:
I would be interested in knowing if any special alloy are required for this application. Also, moving the turbo away from the manifold will probably require other mods (oil lines, intake plumbing, downpipe) that some people may not think of right away.

the trapezoidal flange is specific to our VW application, be it t3 k14 or k24 - all the other t3's in the world use that standard rectangular one

That would probably flow better than our manifolds do, being that the entire exit is as wide as the widest part of our flange.

I was just asking because I'm considering a NA to TD conversion, and if I'm buying parts, I might as well get better performing parts, right? Including a nice T-3, FMIC, worked pump, ceramic coatings, and oil squirters.

Just for chits and giggles can someone measure their trapezoidal flange? Like hole spacing and outside dimensions, I just may be able to use this t25 turbo if I'm lucky.

The measurements might be rough

ohh crap, that means I would definately have to custom make an adapter. I appreciate the cad drawing though, thanks again.
If anyone wants to make me an adapter between this:
and this:
That would be awesome.
