Heres the infamous 20B 3 rotor engine..




We can get them here they sually run about 5-6k and performance parts are hard to find and most people home make their shit,Theres a Guy in RiverView that has one..and I know a guy in Cali that has one,they both have them in a FC (second gen RX7)

The First gen RX7 thats running all motor and runnings 10s all year is powered by a 20B,They are out of Kissime FL..
