Coming Soon

Mazda MX-5 Miata NB (2nd Generation)

19982005 · NB · convertible

The NB replaced the NA's pop-up headlights with fixed lamps but kept the same lightweight RWD formula. Engines stayed BP-series 1.8L flat-fours, with variable valve timing (VVT) added for 2001 bringing output to around 142 hp. A glass rear window with defroster became standard mid-cycle. The Mazdaspeed Miata (2004-2005) added a turbocharged 1.8L making around 178 hp. Note: BP designation simplifies; sub-codes vary by year and market.

Watch out: Owner reports of soft-top headliner peeling on later cars, oil consumption on the VVT 1.8L if the variable-valve-timing system is neglected, and clear-coat peel on the hood and decklid (a common NB cosmetic failure). Mazdaspeed Miata turbo cars often have aging factory turbos that need rebuilds.

Full clubhouse — owner Garage Lineage, common problems, year-by-year notes, and product picks — is on the build list.
