Theres not much to do to a rotary to get good amount of HP..

The Talon deal is good,boost control and turbo upgrade then you in there.

The Honda swaps are to much money to just run 14s,You will be in 2-3k for a nice shell,Then 3-6k on engine swap in parts..

This is how I feel,BUT its your cash and your choices.
I hope yu just buy something that dont brake in your first month of owning it.
