For Sale I have the highly sought after Mazda Eunos Cosmo 20B-REW 3 Rotor Twin Turbo? Motor, ECU, Engine Harness and Ancillaries. THIS IS A LATER MODEL? C-SERIES MOTOR.? Mazda made revisions to the Dowel Pins as well as other areas in the 20B? in order to increase the strength of the plates on the C and D Series Motor.? Top race teams only look for C/D-Series motor in order to build the fastest rotary powered cars in the world capable of 1000+ Horsepower.? Do not confuse this with earlier model A and B series motors being sold by others on eBay that? are worth significantly less.? I have sold 7 of these motors this year ? I only purchase good running Cosmos in order to get the best condition motors.
