Mazda MX-5 Miata NB NR Limited 1.8-Litre DOHC Engine
The NR Limited used the Japanese 1.8-litre S-model as its mechanical basis. Its exact engine code remains unconfirmed.
Engine and application
The NR Limited used the Japanese Roadster 1.8-litre S-model as its basis. Mazda specified a 1.8-litre DOHC engine paired with a six-speed manual transmission. This record concerns that application within the NB generation, rather than a separately identified engine family. Mazda’s announcement supplies the contemporary specification.
Introduction and significance
Mazda announced the NR Limited on 16 December 1999, with Japanese sales scheduled for 18 January 2000. These are announcement and sales dates, not confirmed production boundaries or a model-year designation.
The announced allocation was 500 cars, not a verified engine-production total. The special equipment emphasized appearance and comfort; Mazda did not announce an engine upgrade. This makes the application significant as the mechanical basis of a luxury-oriented Roadster edition.
Specification boundaries
The release does not establish the exact engine code, output, torque, engine manufacturing location or production period. Those details remain unassigned; specifications from other markets or later NB versions should not be substituted.
