For that power level, a single 044 will be fine, even on E85. Unless you're running huge fuel pressure through those injectors, it can't be making more than 350hp at the wheels so it may be quite a happy dyno. That turbo is way, way too huge for that application. You could downsize turbo to a GTX2867R and make that power easily on E85 and it's be on boost WAY, WAY earlier.
I'd just leave everything as-is except for ID1000 injectors and a fuel filter just before the rail and just keen an eye on the filter.
