reddy is proud to introduce the new EP3 Honda Civic Si Turbo kit. The new kits include a pre-programmed E-Manage engine managment system in addition to larger 440cc injectors for smooth, reliable horsepower gains. The turbo kit consists of all the necessary hardware: Greddy T517Z turbocharger (w/integrated wastegate), cast manifold, Airinx air intake, aluminum piping, downpipe, and other miscellaneous parts. 50 extra horsepower gain can be seen running as a conservative 6.5 psi. With optional upgrades suck as an intercooler, additional boost, and a higher volume fuel system, the T517Z turbo in a fully tuned setup has the potential to produce up to 400hp. Intercooler kit will be available shortly, which is recommended in use with the turbo kit.
