In short
- The verified early UK 1.6 makes 113 bhp, while the later catalogue 1.8 makes 129 bhp.
- The 1.8 adds torque and weight, but the signed-off sprint and top-speed figures remain close.
- A later low-output 1.6 or imported Eunos needs its own evidence and is not represented by the early 1.6 button.
The engine badge does not need a second drawing when the visible body is the same. It does need a second set of numbers. Choose the period and engine first, then let the builder carry that specification into the finished print.
Should you choose an MX-5 NA 1.6 or 1.8?
Choose condition before engine when buying the car. For the print, choose the engine that the VIN, dates and records establish. The builder’s 1.6 is the early UK car, while its 1.8 is the later UK specification.
The MX-5 NA buyer’s guide puts shell condition ahead of this comparison. A clean 1.6 does not become the wrong car because a table gives the 1.8 more power.
How do the verified 1.6 and 1.8 figures compare?
The early 1.6 is lighter at 955 kg and makes 113 bhp and 136 Nm. The later 1.8 is listed at 1014 kg with 129 bhp and 152 Nm. The signed-off 0 to 60 and top-speed figures differ by only a tenth of a second and 1 mph.
| Figure | Early 1.6 | Later 1.8 |
|---|---|---|
| Years | 1989 to 1993 | 1994 to 1997 |
| Engine | 1.6 L B6ZE inline-four | 1.8 L BP-ZE inline-four |
| Power | 113 bhp | 129 bhp |
| Torque | 136 Nm | 152 Nm |
| Weight | 955 kg | 1014 kg |
| 0 to 60 | 8.8 sec | 8.7 sec |
| Top speed | 121 mph | 122 mph |
The power values are bhp, not the familiar 115 PS and 131 PS numbers copied under another unit. Jonathan approved each variant separately because every line in the block changes.
Why is the year important on an MX-5 NA 1.6?
Mazda sold a later low-output 1.6, and this comparison does not represent it. The builder’s 1.6 button is bounded to the original 1989 to 1993 UK specification, so a later car needs its own engine evidence instead of the nearest matching capacity.
An imported Eunos Roadster also needs its market and specification checked. A shared body shape can make the drawing appropriate while the UK figures remain wrong for the engine. If neither verified choice describes the car, send its details before ordering.
Why does one MX-5 NA drawing cover both engines?
The catalogue uses one drawing because the engine change does not require a different visible body portrait. A specification variant changes the numbers only. If a facelift changed the face, it would need another model and another drawing.
That rule prevents two identical catalogue tiles while keeping the finished poster honest. The Fiesta generation guide shows the other side of it, where visibly changed faces have to remain separate cars.
Which sources support this MX-5 comparison?
Mazda UK supports the first-generation history and the arrival of the 1.8 in the UK range. The exact figures and periods shown here come from the two separately verified catalogue variants, not from a mixed internet specification table.
Read Mazda UK’s first-generation and special-edition history. Then use the individual car’s VIN, dates and documents to choose between the two options. When they agree, open the MX-5 NA builder.
Questions people actually ask
- What is the difference between an MX-5 NA 1.6 and 1.8?
- In this verified UK catalogue comparison, the early 1.6 covers 1989 to 1993 with 113 bhp and 136 Nm. The later 1.8 covers 1994 to 1997 with 129 bhp and 152 Nm. Weight and every printed performance figure also change.
- Is the MX-5 NA 1.8 much faster than the early 1.6?
- The signed-off catalogue figures are close: 8.8 seconds to 60 mph for the early 1.6 and 8.7 for the 1.8, with quoted top speeds of 121 and 122 mph. Those values describe these two UK specifications rather than every market version.
- Does the builder include the later low-output MX-5 NA 1.6?
- No. Its 1.6 button represents the original 1989 to 1993 UK specification with 113 bhp. Mazda later sold another 1.6 specification, so an engine size without the year and market is not enough to select the correct poster figures.
- Can one drawing represent both MX-5 NA engines?
- Yes. The signed-off catalogue model records no body-panel change that requires a different portrait between these two UK engine periods. The drawing stays the same while the selected engine changes every figure in the specification block.
