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. 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.
