This is our specific Kappa chassis version of our ZZP Z57 turbocharger upgrade for the LNF engine. Since 2017, we have sold several hundred of our popular Z54 model turbos. However, many people asked if we would ever release a larger model of this design. We took these requests and decided not to release a Z54 with larger wheels. Instead, we designed the new turbo with many more upgrades! All Z57s also come with Inconel wastegate hardware for more durability in extreme conditions. We then added a V-band compressor outlet for easy customization to different platforms and engine combinations. These last two upgrades found their way to the Z54 line of turbos as well. We have now developed a version specifically for the Kappa chassis Solstice and Sky. The Kappa version includes specific lines, coupler, and billet wastegate actuator. 

Testing of the Z57 has been nothing short of spectacular. Our two test vehicles both quickly surpassed 500whp at moderate boost levels. We set out to build a turbo that closely compares to our EFR 7163 offering, but at a more affordable price point. This goal was achieved, and we are very excited to see the Ecotec market take advantage of this new boost in the horsepower per dollar realm.

Our Z57 turbo is designed to bolt in place of the factory K04 turbo on the LNF engine. It allows you to reuse your existing intake and exhaust parts without any adapters. While boost will still be controlled by your ECM, you will need to have your tune set up for this turbo. The wastegate duty cycle chart is the main area that needs to be modified. Since this turbo is fully manufactured and marketed as a ZZP product, it also carries our standard 2 year warranty. Comes with all necessary hardware, Kappa specific silicone coupler, coolant, and oil lines for installation.
