Turbo k24 in an ek? You must have a ton of cash sitting around doing absolutely nothing!
If you've got it, why not, I suppose? But serisouly...lots of money.
For simplicity, you cant go wrong with a b20 swap, but the sleeves dont really hold up to too much power, being as thin as they are. This is really something I suggest against going b20 turbo, unless theyre sleeved (which wasnt a choice you gave anyways
)
The things you put up, are vastly different.
I think you need to do some rethinking on your project. Decide on goals you want - power, price, reliability, etc
And no one needs 5lug
If you want to use itr+ calipers, just use ex+ knuckles and redrill the rotors to 4x100
