Wasn't that special, just set up correctly.
Remember, the WMI helped me get away with such a small rear housing.
Next size up (0.82) achieves 300rwkw pretty easily.
There isn't much more left in it after that though, as the compressor is nearing its limits. (unless you're using e85)
I hadn't done this, but if you're changing your turbo you'd have to be stupid not to remove the factory manifold, hit it with the die grinder and take some of the lumps out of it, face it, replace all studs, and use oval nuts.
Would take a few hours more for a big gain.
