Banzai Racing rebuilds all Mazda RX-7 FC3s, FD3s & Cosmo rotary engines using upgraded heat resistant Teflon® Encapsulated Coolant Seals, and Viton® Oil Control Seals and O-Rings. We use RWS 2-piece 2mm Apex Seals, that have 700% more bending strength and are 85% harder than other aftermarket competitors. Additionally, we use all new Apex Seal Springs, Side Seal Springs & Corner Seal Springs. We upgrade to FD3s Corner Springs on all 13B & 13BT rebuilds.
