When you are ready to go above and beyond the power output stock turbos can produce, but still want the response and reliability of a stock Twin Turbo Z, Z1 offers the 500 HP Twin Turbo Z Power Package. This kit is proven to increase output ~100 rwhp over what stock turbos can provide.

To transfer this added Horsepower to the wheels Z1 recommends the Z1 TT Street Clutch Kit with the six puck disc option. Also, to increase the power output further, consider the Z1 Lightweight Flywheel which can be purchased with the clutch kit at a discounted package price HERE.

The 500 HP Twin Turbo Z Power Package is sold based on the assumption that basic upgrades are already be in place (ECU Upgrade, Intake, Exhaust, etc.). If not they should be purchased before moving forward with the 500 HP Package. These basic upgrades can be found in our 400 HP Twin Turbo Z Power Package or sold separately here on
