Vehicles that are already equipped with factory turbochargers have engines with large potential for power that cannot be fully obtained by using the original turbocharger(s). After upgrading 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 GReddy turbo upgrade kit, you can experience new levels of power. Our kits are designed for some of the most popular vehicles. For many, we offer various sizes of turbo kits from mild upgrades to full-on race ready kits with SUS manifolds and external wastegates.
