Rebuilding the rotory is suggested by the best tuners every 50k miles because it's NOT that hard to do. Pulling the engine in a rotory is easy, and it's TINY, one person can lift it easy. They are stupidly simple, but people are scared of them because it's not a conventional design. The bearings are the wear items, and if they fail, it's bad... But they're easy to replace, there are only 2 of them and the concentric, ect...very very simple, if you can work on a normal car well, rotory is easy.
RX-7's have crap for torque, and only until the wind up do they actually start to fly, race one in a supra and you'll beat em off the line and all the way to 60 easy....then the stupid RX-7 starts pulling....HARD.
FYI, the wankel engine (a rotory) was actually designed as a supercharger. Much like the turbo was designed as a supercharger, then they decided to put the fuel directly in and got the jet engine.
The last bodystyle RX-7 is the best, light, great handling, best engine, and ALL where twin turboed. If you're looking for reliabilty, the Supra is by far the strongest of the bunch, and except for the clutch on the MKIV, the rest of the car will handle well over 2x the power (over 1000hp on the stock tranny and drivetrain is the norm it seems).
Personally, it would be Surpa, RX-7, Z, 3000GT, Eclipse. My friend owned an eclipse turbo AWD...it was alright, but not nearly as nice as my MKIII, nor as fast in stock form.
