Welcome, and enjoy your build!!
You know what you're looking for, and have obviously done substantial research, so my only comment is that I'm not 100% sure that "300whp", "reliable" and "daily driver" are words that go together in the same sentence...
It sounds like an exciting project though!
I agree with Moe - the track day at Zwartkops on 25th May could be a useful source of information/opinion for you.
Hope to see you there.
