How often do rotary engines need to be rebuilt?
Factory-spec Mazda 13B rotary engines typically need rebuild every 80,000-120,000 miles. Turbo 13B-REWs used in the RX-7 FD3S have shorter rebuild intervals (60-100k miles) due to higher thermal stress. Proper maintenance (regular oil changes, coolant replacement, driving above 4,500 rpm to burn carbon) can extend intervals.
