Since the release of our ZFR bolt on turbo for the Ecotec platform, it has been a very popular product. Our ZFR turbos offer an amazing combination of high horsepower potential with minimal turbo lag. However, the dual ball bearing system and titanium-aluminum alloy exhaust wheels add a considerable amount to the price of these turbos. For the last two years, we have been in development of a more affordable version of our ZFR 6758 turbo. So far the results have been very impressive. Our new journal bearing Z54 turbo has been tested to extreme power levels and it performs even better than most were expecting. With a full list of ZZP parts on our ’08 Cobalt SS, we achieved 480 wheel horsepower on E85.

Our Z54 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 still 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.
