Thoughts on a K24A4 swap? (self.miata)

I know KPowerIndustries has a K24A2 kit - I found a really cheap k24a4 junkyard engine for $200, 170k miles on it.

I want to keep it in my garage and take it apart and mess around several times as I've never worked with cars too much. It comes with a rebuild kit previous owner had gotten to busy to finish. I plan to either sell it or junk it since its mostly to learn - I'll probably look for a more popular 2.5 swap.

But hypothetically, if I wanted to swap a K24A4 odyssey engine, could I do it? I know the compression ratio is lower so might need some forced induction to go with it

If you've never swapped an engine before, picking a swap that requires fabwork/orientation changes is a bad idea. While I've never personally done a 2.5 swap in an NC (since I have an NA6), it looks fairly straightforward.
