Performance Package NC 1.8 TC300

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 300 HP (Track Mode)

Stage 2 features our GBC20-300 turbo kit mounted to a freshly built turbo engine. The block is bored and honed, fitted with forged pistons, upgraded rods, and reinforced bearings. The cylinder head is fully reworked with new seals and precision-lapped valves.

Additional upgrades include:

• Sports catalytic converter
• High-performance water radiator
• SPS oil cooler kit
• High-flow fuel pump
• Return-capable fuel rail
• Reinforced clutch
• New spark plugs
• Oil change to Motalin 10W-60 HP Racing incl. filter

Note: The car is registered and delivered with 225 HP. Full 300 HP is unlocked via a switch and is track-only. Use on public roads is not permitted.

Important: Full power is only achieved with an exhaust system featuring at least 55 mm pipe diameter. We recommend our Group A exhaust system. Without it, the 300 HP target will not be reached.

Transmission Recommendation

We strongly recommend upgrading to the MX-5 NC 6-speed transmission for this package. The stock 5-speed gearbox is not designed for sustained high torque.

TÜV registration

⚠️ 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.

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!
