Mazdaspeed MX-5 Miata

Mazdaspeed MX-5 Miata (NB) records one precise Mazda performance-car configuration from 2004–2005. The Mazdaspeed MX-5 was Mazda’s factory-turbocharged production interpretation of the second-generation roadster.

At its centre is a 1,839 cc turbocharged inline-4 identified as BPT. The cited manufacturer material supports 133 kW (181 PS) for this scope and 225 Nm. A factory turbocharger, intercooler and six-speed manual distinguish the Mazdaspeed version of the NB roadster.

The powertrain sits in a longitudinal front-mid engine, rear-wheel drive layout and works through a 6-speed manual.

This entry belongs to a deliberately narrow Mazda chronology. Related badges, body styles and competition derivatives can share a visual or mechanical vocabulary without sharing exact specifications. The family tree supplies context, not permission to transfer a recording or fact from a neighbouring model.

The listening cues turbocharged inline-four, six-speed manual, open cockpit, compact exhaust are orientation rather than proof. A cold start can expose idle control and mechanical texture; acceleration can document induction, combustion and shift behaviour; a fly-by can place exhaust and tyre sound in an exterior context.

The focus here is the North American 2004–2005 Mazdaspeed MX-5 Miata. It excludes naturally aspirated NB cars and aftermarket turbo conversions. Many survivors have replacement exhausts, engine work or other changes. An openly licensed recording may still be useful when its exact state is uncertain, but the page will show a visible Unregistered note until evidence resolves the match.

It invites cold start, acceleration and fly-by recordings, as well as photographs, documents and corrections.

A photograph identifies the model but does not prove every detail of a surviving car.

Exact location and ownership evidence stay private while the technical context remains available to later listeners.

That evidence also helps readers compare like with like. A useful submission therefore describes what was heard and how it was recorded, while avoiding claims that the microphone alone cannot establish.

The exact model boundary also keeps the archive useful as the catalogue grows. A reader can follow adjacent generations and special editions without mistaking shared family history for interchangeable hardware. A contributor can attach a photograph, correction or sound to one durable identity, while editors preserve the source, licence and unresolved details that explain why the evidence belongs there.

Preservation means keeping every claim inspectable and correctable. That structure protects the exact identity on which a meaningful sound archive depends.
