You are going to have engineering and registration issues the moment you move away from a 4 cyl 2l NA engine for your car.
First off, find out what is legal where you are.
Second off, work out your budget, $$$ determine the extent you can go to.
Third and last, before you get told less kindly than this, use this forum's SEARCH function. Engine swaps for RA23's have been done to death. All the info you want is here already.
