Question 4

How much power does an MX-5 NC 2.5L swap make?

Accepted Answer

A turn-key MX-5 NC 2.5L L5-VE / Duratec swap makes approximately 195-235 HP naturally aspirated, or 280-340 HP with a turbo conversion. DMS TUNED has completed 200+ of these swaps - more than any other workshop worldwide. See the full cost breakdown at dmstuned.eu/mx5-nc-2-5-swap-cost.

Question 5

Is ECU remapping safe and reliable?

Accepted Answer

Yes, when done properly. DMS TUNED develops each map on the dyno while monitoring air-fuel ratio, knock, exhaust gas temperature, boost and oil temperature, using conservative road-proven targets, and saves your original stock file for a free revert. The real risk is a bad tuner using generic files, not a custom dyno-developed calibration.

Question 6

MX-5 NC turbo conversion vs 2.5L swap - which is better?

Accepted Answer

The 2.5L swap gives reliable ~195-235 HP naturally aspirated with near-stock drivability; a turbo conversion reaches 280-340 HP for more outright power. DMS TUNED builds both and helps you choose based on budget, use and reliability goals - see dmstuned.eu/mazda-mx-5/mx5-nc-2-5-swap-vs-turbo.

Accepted Answer
