You can get an ecu either from Toyota, or possibly on ebay.
The n/a diff will probably handle a bone-stock 2jz-gte just fine. If you're going to upgrade the 2jz-gte with a single turbo, that's when you'll run into trouble.
You'll need to replace the abs ecu and the abs control valve mechanism in order to duplicate the TT brake functionality.
Honestly, by the time you upgrade the entire braking system, and the entire powertrain, you'll have spent more $ than starting off with a full TT Mkiv Supra in the first place...
