Performance Package NC 1.8 SG175

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 175 HP

In Stage 2, we install our SPS header kit for the MX-5 NC 1.8 along with 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 175 HP target will not be reached.

Registration Notice

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

• Friedrich Motorsport Group A

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