This is a simple bolt on larger turbo for your 1.4 turbo Cruze/Sonic. The factory turbocharger is known for the exhaust housing cracking or the wastegate not being preloaded correctly causing slow spool. When you only have a 1.4 liter engine, you know how important spool is, our goal was to make an upgraded turbo that doesn't spool much, if any, slower than stock but still makes more power.

The compressor wheel (inducer/exducer) is 18% larger than stock, and the wastegate diaphram is 2psi higher than stock. Our Sonic gained over 20whp with just this turbo swap. Depending on your current setup (mods, available octane, ethanol content, overall power) tuning and injectors may be required. If you are running the stock injectors, make sure to scan the car to monitor injector pulsewidth and air fuel ratio.

This is a new bolt on turbo, not core based, and it comes with everything needed for the install.  This is a perfect upgrade and we always make our products to be a great price point where it costs less than buying a stock turbo from the dealer.

Nice upgrades to go along with this if you want to make it perform even better is a ZZPerformance Front mount Intercooler kit.
