A TH400 is very street-able, with the Converter technology we have these days, it shouldn't be an issue. Plus TH400s are lighter, and generally cheaper to build.

It's not a gt55. It's a works turbo. On there site it's a utv-9406. With a custom 88mm compressor wheel. And it may just be me but I don't like the sound of such a low gear ratio. And I might look into a th400.
