Mazda class open wheel racers in the Spec Mazda, from Southern California,
run all season without opening the engine.

My son and his friend ran mostly road tracks and got third overall without
rebuilding the engine, in the late 80's. Transmission and tires were the
main work.

You ask, maybe first, if they did some engine work?  Perhaps, but rev
limiters and drivers ability also played into the mix.

Star Mazda claims they have one engine with about five years of racing. 
Most have three years of racing.
