not saying they arent good engines or strong engines, BUT.. the bottom line is that they cannot take NEGLECT and ABUSE like a lot of other motors I can think about (supra motor, ka, sr). rotary motors are very racey, which means they need proper maintanance in order to survive the beating.. and more maintanance than any other motor i've known.
hence the reason each and every person I know who's had an RX7 (including plenty of customers) all say its a love hate relationship -- when it works, its golden.. when it doesnt, its hell. kinda like going out with an anorexic supermodel who likes to have lots of sex.. the ups and downs, how fun.

it's only when you turbocharge the motor that it starts getting finicky. turboIIs last a while but seem to die at 70k or so. FDs are idiotically over engineered in some regards (sequential twins) and then under engineered in others (high heat and a weak ass cooling system). only rx7 people list 'reliabilty mods' as parts of their sigs...
they also die when mistreated *a little*. so buying a used rotary is alot like russian roulette. you never know if the previous owner overheated her or what.
that being said, rx7 n/a rotary motors are VERY reliable when maintained properly. usually this is not hard... flush your coolant every half a year and change your oil at 2000 miles and you are set. my g/f bought her 87 n/a at 160k miles and it still pulls strong (possibly stronger then my s14! T_T). 200k has been reached by some n/a owners.
