Engine of the Day: Mazda 13B

Illustration for article titled Engine of the Day: Mazda 13B

Here's an example of an engine we couldn't really include in the Workhorse Engine of the Day series, because in spite of its incredible power-to-weight ratio and overall screamin' glory, the rotary engine is just not bulletproof enough to be considered a true workhorse. All that's changed with the new EOTD series, however, and we can now celebrate the nonreciprocating awesomeness that is the Mazda 13B. In truth, all the Mazda Wankels are variations on the same design; we just selected the 13B as the flavor that was built for the longest period, 1973 through 2002. Cosmos, RX-7s, 7-second Starlets, you name it, the 13B has powered it. Make the jump for our favorite hypnotic GIF animation. [Mazda, Wikipedia]

Even though I have KOed two of these motors (2nd Gen RX-7) I still love them. I alsoshouldn't say KO to bothof them the first had an excuse, 214,000 miles. It was the oil seals that made me shut that motor down. BTW that motor still pulled like no other even with raw oil shooting out of the tailpipes. My last hoon in that car was on a clear night at about 11:00 PM. At about 11:15 PM the night was no longer clear. The second motor tweaked after racing a 96 mustang. Yes I won, but took out one of the housings in the process. I still love the cars and weep every time I see one in the j-yard.
