APR Turbocharger Kit T4100003-A

This is a brand new turbo designed and developed by APR from the ground up. It does not require a core, and there's no additional downtime associated with other upgrade styles. The turbo bolts to the factory location and connects to factory or upgraded components. This upgrade features matching software for various vehicles and mods, and provides up to 491 Horsepower and 425 Feet-Pound of torque, depending on vehicle platform and fueling, all while keeping emissions components unmodified. The software supports premium pump fuel grades, race fuel grades, and even Ethanol on the Golf R, S3 and TT S platform with fueling upgrades, Since this turbo was designed from the ground up, and doesn't use any of the factory or factory cloned housings or internals, we had complete control over the design. We've upgraded the CHRA to feature German dual ceramic ball-bearings for smooth and reliable operation with better transient response. The compressor cover was upgraded with an appropriate A/R matched to our larger billet aircraft-grade 6061 aluminum 60 Millimeter compressor wheel. We've also provided a large turbo inlet pipe that perfectly matches the turbo's anti-surge compressor cover and connects directly to your factory or upgraded intake system. We've completely done away with the turbo muffler assembly providing the turbo with a larger outlet and smoother transition. The compressor cover even features a port for a turbocharger shaft speed sensor should one suit your build. The turbine housing is cast with 310 stainless steel that's designed to take the heat and abuse seen on a road course. The turbine A/R is perfectly matched to our new nickel-based superalloy K418 54 Millimeter turbine wheel. The system will see low exhaust gas temperature, low exhaust back pressure, low turbo discharge temperature, and low shaft speeds because the system has been properly designed from the ground up for the prescribed power levels.
