i don't think the demand is there for them. i couldn't see selling more than 10 of these things. even fewer at $700 a pop.

I want to make something like this for my twin scroll GT3271 this summer. I would probably build it a bit different though. And holy ---- are those people proud of those things. Cost more than my turbo did. :1

I thought honda tb plates were made of tenzo aluminum 713 I believe.

But on a seperate thought can the exhaust housings be made of some kind of brass like C922 or C876 or something.
B/C I can try to get some made at the foundry I work at. I know most of the brasses we melt require at least 1900 deg F.

good idea but i think you could spend your $700 a little better, might make one over winter break
