Greg, I have a GT35R with a 0.78 A/R divided inlet housing on the GSF headers. Spool is amazing! I'm not after big top end HP, just quick street spooling
For your application, I'd highly recommend a slightly smaller GT30R, rated at 500HP. That would be an awesome turbo for your application IMO, if you're specifically after a BB solution.
