Put in a built 1.8 VVT. Then a TSE setup and call it a day.
You are wasting time and money trying to make 300hp in a 1.6 reliably.,BUT shameless plug with a MKturbo setup and running ALLOFIT for boost you should get there.

Realistically to hit 300whp reliably in a 1.6 you need a built motor, a large turbo, and a lot of boost.
The cost of building a 1.6 is the same as building a 1.8. It will take several thousand dollars, so an extra $500-1000 for a 1.8 engine is a small drop in the bucket.

Little bitty ports and runners make it tough. Airflow is much more restricted than on a 1.8. It isn't just about displacement. It really isn't even mostly about displacement. It is about airflow capacity. A 1.6 with giant Honda style runners and ports could do it much more readily.
But, if I had to do it and budget was not an issue:
1. Send head to be ported by someone with Miata specific experience
2. Oversize valves
3. Custom intake manifold with skunk2 TB
4. Little bit bigger cams to open valves longer and further since ports are small
5. built bottom end with 8.4 C/R
6. MK Turbo manifold and 3in downpipe so it will spool well and because MK Turbo is the best 1.6 setup in the world right now
7. small EFR (or gtx2863R with .63 A/R if the EFR was out of stock)
8. MS3
9. E85 or water injection depending upon availability
