Product description:

The 660 hp kit for the RS3 8Y is designed for drivers who want more than just peak power. At the heart of this upgrade is a rock-solid hardware foundation that allows for a significant increase not only in power but, more importantly, in torque —a difference that is immediately noticeable while driving.

By boosting engine performance while reducing compression using HP special connecting rods, the setup can be designed to be both more aggressive and safer. The result is noticeably higher torque that kicks in earlier, more pull from low RPMs, and a significantly more confident driving experience. Compared directly to a classic Stage 3 setup on a stock engine, this upgrade delivers a much more powerful, stable, and refined driving experience—not just at the top end, but across the entire usable RPM range.

The TC Turbos X6 turbocharger used here delivers the perfect balance of quick response and strong peak power. Combined with optimized intake, exhaust, and cooling systems, this setup is capable of consistently delivering its full power even under high thermal stress—whether on the road or during spirited driving.

Depending on the intended use, the system can be configured with different exhaust and intake options, ranging from maximum flow and sound to a more subtle design suitable for everyday use.

TÜV certification is possible provided that the OPF-TÜV downpipe is selected and the software is supplied by us.

This stage is the right choice for anyone who wants to take the RS3 8Y to a whole new level of performance—with a significant increase in torque, a clear distinction from the Stage 3 series, and hardware designed to deliver this level of performance over the long term.



IMPORTANT: There is no installation, no individual software tuning and no TÜV registration by HPerformance. This kit only represents the required hardware for the respective performance level. The shipping costs for sending in the turbocharger (if no new one is selected) are borne by the buyer!

Please note: Performance and acceleration values can be influenced by various external influences, fuels or additional hardware installed and ultimately the general condition (including mileage) of the engine. The values given are for guidance only and are not binding. With regard to legality and approval in the area of the StVZO we refer at this point to our general terms and conditions.

The perfect hardware!

This hardware kit takes the RS3 8Y to a new level: over 650PS are possible with these components after suitable tuning! The core component is the TC Turbos X8 upgrade turbocharger which, in combination with targeted fresh air optimizations, ensures maximum torque right up to the limiter. Improvements in all areas give the RS3 a powerful but TÜV-compliant sound. Crucial in this performance level: the Engine Pack 1 - a targeted engine reinforcement that designs the pistons, connecting rods and other internal components for the higher load and provides the necessary stability.

This level is the result of months of development work – including road approval, bench testing, and detailed optimization. HPerformance is currently the only provider that can achieve this level of performance legally and permanently .

Level 4 – for those who want the maximum without compromise.
