Being an RX-7 owner with a 13B these engines are very reliable and fast if you super B it you can blow away anything.They tested the 13B at 14000 rpm for 300 thousand miles and it never blew the 12A,s had the real apex seal problems ok so there not that fast off the line but once you get that rotary spinning look out.But that was funny!
my bros. had a 74 mazda RX-4, car would never die, rotory eng., dual coils, we would rally that car all up and down places 4x4s wouldnt go, same thing 100 miles an hour everywhere, ok 95mph
