It takes a tremendous amount of money and time to successfully increase the power of a naturally aspirated engine. With a GReddy bolt-on turbocharger kit you can obtain instant horsepower gains with less time and money while still having the potential for upgrading. Unlike most turbo kits on the market today, GReddy kits are designed specifically for driveability and reliability, as well as performance. Since they are based completely on stock engines, these kits come with all the necessary basics, including fuel enrichment. Many of the kits are covered under CARB E.O. numbers which make them 50-state street legal. If competition use is your goal, there are many GReddy upgrades (intercoolers, blow-off valves, fuel management and boost controllers) to boost the power output even further.

Greddy Performance Turbo Upgrade 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). 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.

Greddy Full Auto Turbo Timer

The basic function of a turbo timer is to allow the vehicle to idle the engine for a timed period, with the ignition key removed. This allows the engine oil and turbo center cartridge to cool down and prevent internal turbo damage.
GReddy Full Auto Timers pack tons of features into one economical, compact unit. In addition to two standard programmable count down presets (P-1, P-2), the GReddy Full Auto Timer also has two auto timer modes (A-L, A-H). The modes estimate the driving RPM according to the vehicles alternator signal and then recommend a count down time.
Also new are the stopwatch/lap time and attack modes along with a built in voltmeter and speedometer. Still standard are the optional parking brake and speedo safety hook-ups.
If you have a turbocharger,whether it's factory, added or upgraded, the Turbo Timer should be included in your budget under the category: (peace of mind). The Turbo Timer allows you to leave your vehicle while the timer leaves your engine running anywhere from 10 seconds to 9.99 minutes. The gradual cool-down prevents bearing damage that can occur when a turbocharged engine is shutdown abruptly after normal driving.

Valves Greddy Blow Off Valve

Greddy Blow Off Valve Type RSThe Type-RS represents the next evolution of the blow-off valve. In a new compact frame, this dual-spring, 40mm valve can discharge a very high capacity, with quicker response and the ultimate in blow-off sound with its new discharge funnel. If the throttle plate is closed while engine is making boost, the compressed air will return to the compressor housing which causes "compressor surge" and also damages the turbine shaft. In the same condition, the GReddy Blow Off Valve will release the compressed air from the charge pipe to protect the turbocharger from the pressure spike and also gives quicker boost recovery. By modifying the vaccum line routing, it can also be used as a Relief Valve.
