Never had a Mazda, but I've been told the rotary engines run like striped-ass apes...the higher they wind the more they wanna go. I understand overhauls are a problem, though.
My wife road raced a Mazda with a stock engine but rebuilt to overcome the early rotary overheating problem. The engine builder said that if the over rev buzzer ever went off (in other words quit buzzing) to down shift. Unbelievable rev ability, but incredibly small brakes. She did a complete brake job every Saturday night after the the 1st qualifying session.
