CI Motorsports Stage 3 Head Porting Service Eclipse / Talon 4G63

Stage 3 - For Pro Street and Strip Turbo Application We don't recommend this head for daily driven vehicles. If your running high lift cams and larger throttle body setup with the addition of plenty of boost then look no further! All top end performance! Her is what we do: Open up Ports below the Valves - you will lose power down low but gain it up top. Changes to Intake Port required. Tubular Exhaust Manifolds are a must, along with larger Throttle body and race intake manifold! More blending of combustion chambers to establish faster flow around valves. Intake Ports and Exhaust Ports are opened up for more flow. These Heads work well with large turbo-chargers Expect to see big gains above 3500rpm, this porting will make you loose a ton of low end torque but if your running a huge turbo and big boost top end performance is amazing! This is a service only.. You must send us your head. We do not offer head exchanges at this time.. Please call us for more information.  We can do either 6 or 7 bolt heads!
