Yes we are the Borg Warner guys they called. But I was under then impression it was a front mount setup. Now once I was told rearmount, then yeah, the setup needs to be changed greatly, especially when it was mentioned to me (streetcar and fast spool) in the same sentence as rearmount. So yeah the TC76 will do what you want, and still make some good power.
As for race covers....yes. At higher PR's a larger A/R cover can make a substantial difference on the total output of the turbo. Of course we are talking peak #'s. An average setup that runs 65-75% of total power output of the charger will more then likely only see a few HP increase. Its all relative.
