GReddy 1993 2002 Toyota Supra JDM Model JZA80 T78 88 Turbo Kit 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). Big gains can be found by upgrading the exhaust, intake, blow off valve and intercooler and adding more fuel and boost, but by also replacing the stock turbocharger with a properly sized GReddy turbo upgrade kit, you can experience new levels of power. Kits are available for most popular Japanese turbo vehicles, and for many, we offer a selection of kits with various sizes of turbos from mild upgrades to full on race ready kits. Depending on application, kits will either bolt onto factory manifolds with integral wastegates or use hand made SUS manifolds with external wastegates. NOT CARB LEGAL. NOT FOR SALE IN CA.
