About four years ago I was considering making a TT low mount that would be compatible for the 7AT. I think there are enough upgrade paths for the 7AT that would make a smaller turbo solution viable. Heck... These little VS Racing turbos were rated around 600.
Not trying to say my garbage was the same quality as your stuff either. Just an option you might want to look at. I scrapped my low mount TT in favor of a "cheap" LS swap... which the financial boat is still taking on water... lol
