Mazda MX-5 tuning — every build we publish, we measured
One platform, since 2015: NA, NB, NC, ND. Factory-ECU calibration, the 2.5 swap, turbo conversions, standalone. 1,500+ MX-5 dyno runs logged, 133 to 450 hp — and remote tuning that reaches any garage in Europe.
Pick your generation
NA / NB (1989–2005)
Standalone territory: MegaSquirt MS3, MaxxECU, ECUMaster. Our measured NB builds run to 450 hp / 500 Nm on a built 1.8, and a stock-internals 1.6 turbo made 170 hp.
NC (2005–2015)
Our main line. Factory-ECU tuning via MazdaEdit/VersaTuner, the 2.5 L5-VE swap (183–236 hp NA), and the turbo kit to 370 hp.
ND (2015–)
Stage 1 measured: 1.5 from 131 to 154 hp. Honest expectation setting — the ND responds, but the margin is smaller than forum legend suggests.
The measured MX-5 database — top builds
Every row is a real car, before and after on the same in-house dyno. The full 86-car database across 20 brands is on the dyno page.
| Car | Setup | Power (hp) | Torque (Nm) |
|---|---|---|---|
| MX-5 NB | 1.8 — Custom Tune | 140 → 450 | 170 → 500 |
| MX-5 NC | 2.0 — Custom Tune | 160 → 370 | 178 → 430 |
| MX-5 NC | 2.5 — Turbo Kit | 175 → 344 | 225 → 455 |
| MX-5 NC | 2.0 — Turbo Kit | 160 → 339 | 189 → 442 |
| MX-5 NC | 2.0 — Turbo Kit | 160 → 278 | 190 → 329 |
| MX-5 NC | 1.8 — Turbo Kit | 125 → 275 | 178 → 340 |
| MX-5 NC | 2.0 — Turbo Kit | 160 → 272 | 188 → 341 |
| MX-5 NC | 1.8 — Custom Tune | 125 → 270 | 178 → 340 |
| MX-5 NC | 2.0 — Custom Tune | 160 → 247 | 190 → 281 |
| MX-5 NC | 2.5 — Stage 2 | 125 → 236 | 176 → 290 |
| MX-5 NC | 2.5 — Stage 2 | 175 → 226 | 235 → 281 |
| MX-5 NC | 2.5 — Engine Swap | 125 → 221 | 168 → 271 |
Reading it honestly: the 450 hp NB is a fully built engine. A straight 1.8 → 2.5 swap lands at 183–221 hp. A stock NC 2.0 Stage 1 lands at 177–190. We tell you which band your car is in before you pay.
Remote tuning — your MX-5, any country in Europe
Most of our MX-5 work never sees Athens. The loop: you send the stock ROM (MazdaEdit, VersaTuner, EcuFlash — we tell you the cheapest route for your car), we send a calibration written against your VIN, you drive the log profile, we revise until the log is clean. Revisions are in scope, not billed per round.
From €450 ex VAT. The full remote process is here — and if your engine is a fresh 2.5 swap running the stock 2.0 map, that calibration is not an upsell, it is the job.
The 2.5 swap — the shortest route to a fast NC
The L5-VE 2.5 from the Mazda 3/6 into your NC: 183–236 hp naturally aspirated, 225–290 Nm, measured across twelve swaps. Four ways to buy it — DIY kit, trade, fitted from €4,500 ex VAT. Part numbers, the three mechanical traps and the automatic-donor gearbox issue are all in the DIY guide.
Turbo — when the swap is not enough
Measured turbo builds: NC 1.8 to 275 hp, NC 2.0 to 370 hp, 2.5 turbo to 344 hp on the kit and 430 hp on a built engine. The DMS turbo kit page covers 1.8, 2.0 and 2.5 Duratec applications.
Why one shop, one platform
Because the failure modes of this chassis are known here, not discovered on your car. We know the NC ECU flashes clean over OBD — no bench, no soldering, no cut loom. We know the 2.5's oil pan fouls the subframe and the donor pulley has the wrong tooth count. We know what a tired NC clutch does at 270 Nm. That knowledge is the product — the dyno just proves it.
Every calibration is issued per VIN and archived with your stock ROM. No VIN, no tuning.
FAQ
