mine went out during a 15 psi run on a cold night....my own fault.....I was racing my roommate in his WS6 and I kicked his *** royally, I should have just let off the gas as soon as I had him, before I hit fourth....that extra 1/2 psi did me in

anyway, unlike JimLab, I'm convinced the rotary engine is not instrincally unreliable, as long as you stay within it's admittedly small window of operation and replace the crap stock cooling seals with teflon coated....

anyway, I'm going with a reman engine from Malloy Mazda, I've heard great things....all new housings and rotors for $1950.....not a bad deal at all
