    APR T2100012 Details

    APR's Transverse 2.0T FSI Audi S3 and VW Golf-R K04 Turbocharger System will upgrade your current 200hp and 207lb-ft Transverse 2.0T FSI Engine with the necessary OEM components from the European Audi S3 and Golf-R along with APR's Direct Compressor DV Recirculation Port, CNC Turbo Outlet and meticulously recalibrated Engine Management to produce 355 horsepower and 368lb-ft of torque on 100 octane gas. Reliability, drivability and enhanced performance that cannot be bested are the highlights of APR's newest OEM-component based conversion package.APR's engineers have expertly recalibrated the engine management system to allow for nearly flat torque delivery from 2500 rpm's to 5000 rpm's which results in a smooth linear pull throughout the power band. Keeping the track enthusiast in mind, this conversion package will not result in overpowering of the Driveline but will allow for smooth acceleration to easily maintain control while cornering.The Borg Warner K04 turbocharger selected by VAG engineers is perfectly sized for the 2.0 liters of displacement to allow for stout horsepower numbers as the rpm's increase with no fall off as redline approaches. This ensures plenty of power in the high rpm's for continued acceleration in the straights or for shifting back into the healthiest portion of the power band at the drag strip.One of the greatest benefits to the APR K04 turbocharger system is its simple, yet elegant design. APR's CNC machined direct compressor recirculation port on the OEM compressor cover significantly reduces engine bay clutter and saves the end user from the hidden costs of purchasing extra throttle body pipes, hoses, clamps and DV mounts for recirculating boost pressure. The compact design also removes extra charge piping volume to allow for lightning fast boost response and less locations for boost leaks. Furthermore, charge air pressure is directed directly at the compressor wheel which helps keep the turbo spooled upon lifting the throttle, minimizing turbo lag.The OEM k04 turbocharger features a turbo muffler designed to reduce turbocharger sound in the cabin that also creates a restriction in the boost pressure delivery stream. APR removes the turbo muffler not only to enhance the sound of the turbocharger, but also to smooth the airflow across the previously baffled muffler section. This also eliminates the need to Purchase an OEM S3 turbo discharger pipe. A clean and simple CNC flange developed by APR's Engineering Team is bolted directly to the compressor cover in place of the OEM turbo muffler. A long mounting surface provides an excellent slip proof surface for mounting the silicon discharge hose and an o-ring between the flanges ensures a life of leak proof operation.
