CI Motorsports Stage 3 Cylinder Head Porting Service Eclipse / Talon 420A

Stage 3 - For Pro Street and Strip Turbo Applications. 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! Open up Ports below the Valves - you will lose power down low but gain it up top. Changes to Intake Port required. Headers a must, along with larger Throttle body! 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 turbochargers Expect to see big gains above 3500rpm, this head will make you lose a ton of low-end torque but if you're running a huge turbo and big boost top end performance is amazing! This is a service only.
