rx7

Also known as the Savanna in Japan, it has 3 generations. 1st gen - FB3s 2nd gen - FC3s 3rd gen - FD3s The Rx7 was only one of the many cars that were powered by the rotary engine. Dr. Ing. Felix Heinrich Wankel invented this type of engine in the 1950's. This design was bought by Mazda and used in many of they're automobiles from the 1960's - today. 12A (1.2 liter twin rotor n/a) 13B (1.3 liter twin rotor n/a / turbo) and 20B (2.0 triple rotor n/a / turbo) are some of the rotary engine codes that are well known. The engine sits just behind the Rx7’s strut towers making it a true front mid engine car which gives the car great handling characteristics and the proud owner bragging rights. The turbocharged rotaries are terribly unreliable and in reality have to be overhauled every 70,000 miles. The apex seals are one of the weakest points in the motor, second warping the rotor housing from over heating occurs very often. These cars have terrible gas mileage and are not pleasant to drive behind with your windows down. A rotary engine burns oil from the factory to lubricate the rotor housing walls. Failure to pamper these cars will result in a blown engine very early in the cars life. These cars have a very hard time passing smog tests with high milage. Rx7’s are great cars from beginning to end, I love them, but I already have a girlfriend that needs enough maintenance.. my 240Z does me just fine.
