Stand for Rotary project 7. The engine uses no pistons. It has less parts than a piston engine, which means less friction. Rotarys are unique to the piston, and are a whole nother ball game to fix. It came in in 2 popular engine names the 13B which was on the FC 1986-1991 (or in japan 1992) the 13B-RE which is in the FD 1993. The FD was asequential turbo setup, the FC was a single turbo(in the states they were NA or Turbo)(1992 Japan was produced with special FC's the Infini models) both cars offer near 50/50 weight distribution. they are light and potently fast. Those Mustang guys think 1.3 liters is nothing huh? Well, you be suprised how the FC's and FD's can certianly become a challenge for the 5.0 crap. (BTW, all the FC's in Japan were turbo even the convertibles.) The Us did not get as lucky.
