Performance Package MX-5 NC 2,5L Duratec Swap Stage 2

Product information "Performance Package MX-5 NC 2,5L Duratec Swap Stage 2"

This performance package was developed by SPS Motorsport on the racetrack, adapted for street use, and continuously refined. All components are engineered in-house and used in our own race cars — delivering maximum performance, uncompromising quality, and a clean, OEM-like engine bay appearance.

Two Options – Parts Package or Full Installation

You can choose between two configurations:

Parts Package (without installation): Receive all components for self-installation. ECU tuning, dyno protocol, and TÜV registration are not included.
Full Installation (with tuning & registration): All components are professionally installed at SPS Motorsport. The ECU is then individually calibrated on our in-house dyno and on the road — including a dyno protocol. Finally, the entire conversion is inspected and officially registered at our facility. Registration is included in the price.

Power Upgrade to 220 HP / 275 Nm

This naturally aspirated stage features a 2.5L Duratec engine, a Giselwerks intake manifold, our SPS header kit with integrated sports catalytic converter, and a set of performance camshafts. Cam timing is precisely adjusted to ensure optimal power delivery and high-revving response.

Note: Full power output is only achieved when paired with an exhaust system featuring a minimum pipe diameter of 55 mm. We recommend our Group A exhaust system, which can be added as an accessory during checkout. Without it, the 220 HP target will not be reached.

Modular Options – Clutch & Cooling Package

This kit can optionally be ordered with or without:

Clutch Kit (Xtreme Clutch Stage 2)
Cooling Package (Oil Cooler & Water Radiator)

Selection is made during checkout.

Registration Notice

⚠️ This performance package can only be registered in combination with the OEM exhaust system or our Group A exhaust system at our facility. Other exhaust setups have not been tested and may not be eligible for TÜV registration. If in doubt, please contact us via email before ordering to ensure smooth registration.

Accessory Items

SPS Motorsport Group A duplex exhaust system for MX-5 NC

SPS logo: without SPS laserlogo | Tip: Type 25 1x90mm

Our SPS Motorsport Group A duplex exhaust system replaces the original rear and front silencers. The outer diameter of the piping is 63.5 mm. The systems are based on the absorption principle, meaning that perforated pipes run through the silencers. This results in lower exhaust back pressure and therefore an increase in power and torque. Compared to the standard system, it produces a deeper and more powerful sound. 1.8L Duratec 126HP 93kW / 2.0L Duratec 160HP 118kW Stainless steel With EC type approval To schedule an installation appointment, please contact us at info@sps-motorsport.com
