EM800 Turbo Upgrade Kit

The EM800 2.5TFSI EA855 Upgrade Turbo Kit from EM Performance is engineered to unlock the full potential of your 5-cylinder engine. Tailored specifically for Audi RS3, TT RS, and RS Q3 models equipped with the EA855 EVO engine (DAZA/DNWA/DNWB), this turbocharger offers a significant performance increase while maintaining original mounting positions and pipeline compatibility. The core specifications include a high-flow, forged aluminum compressor wheel with a 64mm inducer and 87mm exducer, boasting an efficiency increase of over 30%. The turbine wheel is constructed from stainless steel, featuring a 67mm inducer and 58mm exducer, with an optimized exhaust side cross-section designed to reduce backpressure and improve responsiveness. This combination supports a broad horsepower range from 550 to 880 HP, contingent on necessary peripheral upgrades and ECU tuning. The turbo is compatible with the original oil cooler, water cooler, and exhaust pipeline, minimizing installation time and complexity. The heart-cut enlarged design and optimized A/R ratio contribute to rapid low-RPM spool-up for street-friendly responsiveness, while the robust construction ensures stable, high-boost output suitable for track performance. Beyond performance gains, the EM800 retains the subtle appearance of the original turbo housing, offering a low-key aesthetic. All oil and water passages, along with flange positions, are matched 1:1 with the original component, ensuring a hassle-free upgrade process.
