APR® - K04 Turbocharger Kit with Software

K04 Turbocharger Kit with Software by APR®. apr's transverse engine conversion packages will upgrade your current factory rated 158hp and 180lb-ft transverse 1.8 tsi engine with all of the necessary oem components and meticulously recalibrated engine management to produce 330 horsepower and 335lb-ft of torque on 98 ron gas. APR's engineers have expertly recalibrated the engine management system to allow for a broad torque curve 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 perfectly matches to allow for stout horsepower numbers as the RPMs increase with no dramatic fall off as redline approaches. This ensures plenty of power in the high RPMs for continued acceleration in the straights and positioning at the healthiest portion of the power band after corner exit.

Features

Compact, Stealthy & Reliable Design
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.

High-Quality Turbo Muffler
Compressor Outlet 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. 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.

Reliable Compressor Cover
The K04 turbocharger was originally designed for an FSI engine, and as such, some items not required for the new TSI engine are present. The compressor cover features a port used in the FSI's PCV system, however on the TSI, this same port is located higher up on the intake tubing. APR has provided a gasket sealed laser cut port cover to block off this part and ensure no unmetered air leaks into the system. The design is clean and simple and never requires maintenance.
