The Greddy 02-05 Civic Si Turbo Kit is one of the first of GReddy's new evolution of bolt-on turbo kits. They now include a pre-programmed "e-manage" engine control unit along with the provided larger injectors for smooth, reliable, horsepower increases. The kit also includes all of the necessary hardware including:
a properly size T517Z actuator turbo
Airinx air intake
All the aluminum piping
The basic kit in street-style trim adds a very drivable 50+hp at 6.5 psi, but with 400hp max potential in the T517Z, the kit is very upgradable.
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.
