1.3L (13B-REW) Rotary - Type RB
Petrol
Monitor the oil pressure and temperature gauges closely while idling and under load; erratic behavior can be an early indicator of cooling system fatigue or sensor age.
Check the transition between the primary and secondary turbochargers at 4,500 RPM; a hesitant or jerky sensation during this hand-off may suggest the complex vacuum solenoid system requires some attention.
Observe the exhaust smoke upon cold start and during hard acceleration; excessive blue smoke can be a sign that the apex seals or oil control rings might be due for internal inspection.
Listen for any rhythmic clicking or binding sounds when turning the steering wheel at low speeds, as the FD's steering rack and front suspension bushings have lived a long life and may be showing their age.
Usually marks the point where original rubber cooling hoses start to become brittle and proactive replacement is a common consideration.
A frequent interval where enthusiasts consider a full engine refresh or a compression test to ensure the rotary housings and internal seals are performing to factory spec.
Often the time when original suspension components and shock absorbers may begin to lose their factory dampening characteristics.
Ensure you are checking your oil levels at every fuel stop, as the rotary engine is designed to consume a small amount of oil as part of its operation.
Keep a consistent eye on the coolant levels and ensure the cooling system is free of air pockets to maintain thermal efficiency.
Warm up the engine gently and avoid switching it off immediately after a short run to help prevent flooding the combustion chambers.
Verify that the electrical earthing points are clean and secure, as the FD’s complex electronics rely on a very stable ground.
Replace the spark plugs and ignition leads at regular intervals to maintain the efficiency of the rotary combustion process.
Estimated repair costs if issues arise
Future Budget Planning: Because of the high-performance nature of the 13B-REW, it is wise to eventually account for a full rebuild to replace apex seals and housing surfaces, depending on how the car has been driven over the decades.
Future Budget Planning: The sequential twin-turbo setup is highly complex; if you notice a loss in boost consistency, you might eventually need to budget for a professional assessment or rebuild of the turbo cores.
Future Budget Planning: The 'rats nest' of vacuum hoses under the intake manifold can perish over time due to heat; replacing these is a common preventative task to ensure smooth engine performance.
