Do you think you would have seen the same improvement going to an external wg?

Contrary to what people say, more boost isn't better. In some spots I am seeing more power, but I believe also the exhaust side of the turbo is being strangled by having to flow everything thru the turbine wheel.
since I have a 4-axis CNC in my garage.
^^^pboglio makes big power but he's also trashed 3 built transmissions due to the "insta-hit" of the 16g. Besides we all know the 35 will flow more, a lot more if you have the 7 blade.
Can't you send your cad rendering into those prototyping companies. I can't remember who or where I saw that but they would produce either hard wax copy or maybe plastic. Either way they can ship it to ya.
OK, so with a little google, this is what I came up with.

Pricey but it may be cheaper then cutting a large slab of billet aluminum without knowing the outcome. If you can't tell, I want to hear some updates!
I build dsm transmisions, so i have about 3-5 transmisions on hand at all times. Oh, and a dsm trans is never "built", the best you can do is a 91-92 gearset, and welded diff. They still rip the teeth off of 3rd gear on the intermediate shaft. The 272 cams take some of the hit out of the 16g, and really lenghthen the powerband.
I ran a hx40 on my galant, i think the holsets are fine, but the evo3 on my car now, runs so much better than any of my other builds, with a 16g of course.
Back on track yet?
For anyone thats interested, the reason it failed was a clogged oil line filter feeding the turbo. Why Subaru decided it'd be a good idea to install an oil filter in a banjo bolt is beyond me, but it took out the turbo good. I'd say I now have about 1" of shaft play on the old turbo.
