garrett is now going to offer the tr30r to the public, not much i know about this but im guessing its better then the gt30r now, hard to find info on this, nothings on garrett's site, but their rep at sema states its coming to the public.

It doesn't make a lot of sense to release the TR30 to the public its compressor wheel is specifically designed for restricted applications (rally cars) and the turbine wheel is M247 (unobtanuim) which is ridiculously expensive and only needed if you plan on running full time rally style antilag...

This would be an interesting turbo to try out on the ultra high efficiency F20/F22 engine. Paired with a well designed manifold, I think this turbo would be perfect for 350 rwhp.
Above and beyond that, I'm not sure it would provide any benefit at all. WRC rules mandate fixed geometry turbochargers, and even a well designed turbo only operates in it's peak efficiency over a relatively small range. The 34mm restrictor used in the WRC limits power to about 300 HP, so my guess is that this turbo was designed specifically to provide it's maximum efficiency in the 250-300 HP range. Sure, it will have the ability to move more air without the restrictor, but it will soon be operating out of it's optimum range.
The only major advantage of this turbo is it's exotic material usage. The turbine housing and turbine wheel are designed to withstand the very high temperatures that occur during anti-lag operation. A normal street turbo would fail under repeated anti-lag usage.
From what I read, the Audi R8 used two of these turbos to help create it's 550-600 hp. Again, each turbo is responsible for about 300 HP.
So, in summary, its a fancy Disco Potato.
