This 1000 hp 2.5 TFSI build includes engine internals, cylinder head, airflow, fuel supply and transmission changes. This specification is for the highest-output configuration, not every RS3 or TT RS tune.
Block, pistons and cylinder head
Stronger rods and pistons replaced the factory items, the aluminium block was sleeved and the head secured with stronger studs.
Enlarged intake and exhaust ports and larger valves prepare the engine for this four-figure power target.
Turbo, cooling and E85
A larger turbo and new exhaust manifold replaced the factory hardware. The intake, intercooler and exhaust, including sound-control valves, were upgraded.
A higher-flow in-tank pump and injectors support the E85 configuration. Their specific models are not listed in the build details.
Syvecs and transmission components
Syvecs engine management and traction control were integrated with the vehicle’s driveline.
The seven-speed dual-clutch S tronic received a stronger clutch and limited-slip differential, preparing power delivery to the wheels as well as the engine itself.
