COOLING

One of the best ways to increase performance in a smaller displacement engine, is forced-induction. GReddy Turbocharger Kits and Supercharger kits are engineered for vehicle specific applications. This allows us to tailor each kit for the best match in performance, drivability, and ease of installation. We offer 3 main categories of forced-induction kits along with a host of supplemental products to aid you in our "Total Tune-up" philosophy.

Turbo Upgrade Kits are for vehicles, which already have factory turbochargers. For these models we offer larger turbocharger options to optimize performance at higher horsepower ranges, that the factory system could never supply. Many of these kits include hand-built, tuned, stainless-steel header-type manifolds with large external wastegates, which with proper fuel tuning can produce enormous horsepower increases.

Our line of Bolt-on Turbo Kits, on the other hand, are designed for vehicles which are normally-aspirated (N/A or non-turbos.) For these vehicles we offer easy to install bolt-on kits which include necessary components to convert your engine, including pre-tuned fuel management to increase fuel demands for boost conditions.* These kits offer a simple option to increase power in the 30-60% range, with the potential to produce even more horsepower.

More recently we have added a line of Bolt-on Supercharger Kits (S/C Kits.) to supplement our Bolt-on Kit line. For certain vehicle applications, a Supercharger Kit allows for easier installation and a more responsive power band. Like our other bolt-on kits it includes all the necessary hardware and pre-tuned fuel management.

To increase performance even more, we offer a full array of products to help optimize the performance even more for a forced induction vehicle, including our: Blow-off Valves, Wastegates, Relief Valve, Hard Piping Kits, and very popular, highly effective Intercooler Kits.

^{* limited kits will require separate purchase of fuel management kit.}
