Vehicles that are already equipped with factory turbochargers have engines with large potential for power that cannot be fully obtained by using the original turbochargers. After ugrading the exhaust, intake, blow-off valve and intercooler and adding more fuel and boost, big gains can be found. By also replacing the stock turbocharger with a properly sized turbo upgrade kit, you can experience new levels of power. Our kits are designed for some of the most popular vehicles. Currently, T3/T4, To4E, Audi A6 1.8T, T25/T28, GT35 etc floating bearing turbochargers are available with us.
