Performance parts package 1.6 NB SG145

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 145 HP

In Stage 3, we install our SPS header kit for the MX-5 NB 1.6, a programmable standalone ECU with wideband lambda sensor, 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 or our 3-inch system, which can be added as an accessory during checkout. Without it, the 145 HP target will not be reached.

TÜV & Component Certification

Starting Winter 2021, we provide TÜV component certificates for our performance packages, allowing you to register your conversion directly at your local TÜV station. Once registered, your vehicle is fully street-legal across all EU countries and Switzerland.

⚠️ This performance package can only be registered in combination with the OEM exhaust system, our Group A exhaust system, or our 3-inch exhaust system. Other 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.

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!
