Mazdatrix is a good place to check prices. Here is their engine parts page.

Yea I've decided I'm gonna just rebuild the rotary either through Mazdatrix or Lucky7Racing.

Both of them seem to not be soo bad on price and I can hopefully keep it under 5k.

 

You have to disassemble everything to make sure you're parts are still ok to reuse. That is how your going to be able to determine how much your rebuilds is going to cost. apex seal grooves ok, housings reusable, irons need lapping, porting? The gasket kit alone is $1300

Still cheaper than converting for a swap, but the quality of the rotary rebuild will determine the longevity and compression
