Id advise against engine swaps. The whole reason the car is NA and a flat 4 is for a low centre of gravity. Any other engine is going to mess up the weight distribution and subsequently the handling.
The FA20 is already a great motor. Makes more sense to Supercharge or Turbocharge it rather than swap it out.
I’ve done 8 engine swaps and I basically regret all of them as the reality never quite lives up to the dream. There is a good reason manufacturers choose the engines they do in their cars. They have lots of engineers, designers, accountants and sales people choosing what works best.
