Mazda 13B peripheral Port engine and 55mm ITB’s



Mazda RX7 13b Balanced Peripheral Port Engine **Fresh build**.


This is a serious spec naturally aspirated engine with no expense spared. This is advertised elsewhere so I have the rights to remove at anytime. I am testing the water with this setup as I have spent over a year gathering these parts from all over the world. I am only considering selling due to work situation. In no rush to sell so I won’t be accepting or responding to any low ball offers. I have everything available minus ecu and loom to make this setup complete if needed or you can go carb depending on your needs.
