They do have the 0.49 a/r internally gated T25 now available. Of course, you'd need a vband downpipe. I still think it might be a bit too small and choke off. I am of the opinion with little knowledge or scientific evidence that the 0.72 a/r might be the right size on the VG. They do make internally gated versions in that a/r, but unfortunately only in vband inlet, requiring a new exhaust manifold. I'm hoping someone comes out with a vband manifold that can support external wastegate as well.
I would actually do a custom compressor inlet pipe so you can just use a coupler versus the stupid 2 bolt system that is used in factory form. Or a vband inlet.
