IIRC thats a pretty common size turbo for supra's that put around 500-600whp. Sounds about right be rated around 700hp. Cant wait to see it, maybe even hear spooling if it makes Va in 11.
Funny story bout t67'd supra and my car at a car show. My car was bout 2-3 cars away and a bunch of people just looked at the supra, then my car was next and someone said "damn, look how big that turbo is." someone corrected him but still I stood there laughing in silence. The T-trim compressor is freaking huge though, made the 67 look small.
