Well, I have been on both sides, still a member of se rx7 club, I have owned 2nd & 3rd gen.  Rotaries are sweet, and I will alwys love them but I wanted something with some longevity. I built my best friends 95 r2, t-78, dowel pins , ceramic seals and all. It dynoed at 432rwhp at 17 lbs of boost.  The downfall being you should expect about 80,000 miles from a motor if that.  Then the rebuilding process has to start again.  And a good motor will set you back about 5000. And that is with me doing the labor of setting it in myself.  As far as cost wise, it will take about 20,000 in upgrades to achieve 400 to 500rwhp reliable. It would depend on how deep your pockets were, it would cost alot more to make a wankel fast.
