When should I replace the timing belt on my JDM car?

Typical intervals: Mazda rotaries (no timing belt, chain-driven), Toyota inline-six (90,000 miles/145,000 km), Honda B-series (105,000 miles/170,000 km), Mitsubishi 4G63T (60,000 miles/100,000 km, interference engine critical), Nissan SR20DET (chain-driven, no belt). Check your service manual for exact specifications.
