I would imagine that with proper care, 5 years is not out of the question.
Our resident Central Florida RX7 hotshoe, Marc "Hollywood" Dana, is currently on year 6 and still running up front and winning. Am I right, 'wood?
I think that the key is to start with fresh rotors and housings if you want maximum power and reliability. It costs extra, but then how much does it cost to keep pulling the motor and getting cheap rebuilds?
