Performance parts package NC 1.8 SG156

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.

Power Upgrade to 156 HP

In Stage 1, we install our SPS header kit for the MX-5 NC 1.8. The optimized exhaust flow combined with precise ECU tuning results in a noticeable increase in performance and sharper throttle 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 156 HP target will not be reached.

Registration Notice

⚠️ This performance package can be combined with these exhaust systems:

• Friedrich Motorsport Group A
• Fox/SPS Group A

For other exhaust systems please contact us in advance via email, so we can check first whether a TÜV registration is possible.

Developed with Motorsport DNA

All performance packages are designed in-house and built to be upgradeable — whether you're aiming for a lightweight NA setup, individual throttle bodies, or a turbo conversion. We use only proven components that have earned their place on the racetrack. Engine bay aesthetics remain clean and close to OEM.

Upgradeable & Modular

Our packages are modular and future-proof. If you decide to upgrade later, we’ll provide the necessary support and guidance to expand your setup.

Lifetime Support

Every performance package installed by us comes with lifetime support. Since we use these products ourselves — on the road and on track — we can help with nearly any issue. Got questions? Just ask!
