2023 Audi RS3 - Five-Cylinder Fury Build
2023 Audi RS3 (8Y)
About This Build
The 2.5L inline-5 turbo in the Audi RS3 is one of the most beloved enthusiast engines on the planet. The DAZA-code engine in the 8Y generation RS3 came with significant improvements over the older CEPA/CZGB motors, including a lighter forged crank and improved turbo positioning. This build leverages an Integrated Engineering (IE) turbo upgrade, full exhaust from Milltek, and an IE ECU tune to push the RS3 to 560WHP while maintaining Quattro AWD traction. IE has been the gold standard for Audi 2.5T tuning for years. ## Mod List **Turbo Upgrade:** - Integrated Engineering IE700 Turbo Upgrade for DAZA — $4,500 (https://www.integratedengineering.com) **Exhaust:** - Milltek Sport Non-Resonated Catback Exhaust — $1,800 (https://www.millteksport.com) - Integrated Engineering High-Flow Downpipe — $900 (https://www.integratedengineering.com) **Cooling & Intake:** - Integrated Engineering Cold Air Intake — $400 (https://www.integratedengineering.com) - Wagner Tuning EVO3 Competition Intercooler — $1,200 (https://www.wagnertuning.com) **Fueling:** - Autotech High Volume Fuel Pump (HPFP) — $600 (https://www.autotechracing.com) - Integrated Engineering Fuel Rail + Injector Upgrade — $1,400 (https://www.integratedengineering.com) **Tuning:** - Integrated Engineering ECU Stage 2 Tune — $800 (https://www.integratedengineering.com) - Integrated Engineering DSG Tune — $600 (https://www.integratedengineering.com) **Drivetrain:** - 034 Motorsport Density Line Mounts — $450 (https://www.034motorsport.com) **Labor & Installation:** ~$3,000 ## Performance Results - 560 WHP / 520 WTQ on 93 octane - 0-60: 2.7 seconds (from 3.6 stock) - Quarter mile: 10.3 @ 137 mph ## Build Summary Total parts cost: $12,650.
