After more than a year in development and testing, we are ready to release our new Z57 turbo for the Ecotec platform. 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. 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 motor. 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, v-band outlet adapter, coolant, and oil lines for installation.  Specifications: Compressor Inlet: 2.5” Outlet: 2” V-band Inducer: 57mm Exducer: 71mm Turbine Inlet: K04 Outlet: K04 Inducer: 63mm Exducer: 56mm Note: Does not fit LNF 2.0L Saturn Sky Redline or Pontiac Solstice GXP. Kappa version of the Z57 is currently in development.  Fitment note: Our Z-series turbos and ZFR turbos do not work with the stock intercooler charge pipes on an LHU Regal. Our intercooler kit is available here.
