Frequently Asked Questions
Does this manual cover both the NB1 and NB2 versions of the Roadster?
Yes. The manual spans the full NB production run, encompassing NB1 cars built from 1998 to 2000 and the refreshed NB2 models produced from 2001 through 2005. Variant-specific differences in trim, suspension tuning, and equipment are addressed throughout the relevant sections.
Is this the same car as the Mazda MX-5 Miata sold in the US?
Yes. The Roadster name was used primarily in Japan, while North American buyers knew this generation as the MX-5 Miata. All share the same NB platform and BP-series powertrain, so the technical content in this manual applies directly to US-market vehicles.
Are wiring diagrams and electrical diagnostics included?
Full electrical coverage is included: complete circuit diagrams, wire color codes, connector pinouts, ground point locations, and step-by-step troubleshooting flowcharts for the engine management, fuel injection, lighting, and climate control systems.
What format is the manual?
The manual is a PDF file delivered by instant download. It is fully searchable, zoomable for detailed diagrams, and compatible with Windows, Mac, Linux, iOS, and Android devices using any standard PDF reader.
