This is our third version of our simple bolt on larger upgraded turbo for your 1.4L turbo Cruze/Sonic. After extensive R&D testing with the stock frame we discovered that the outlet going from the head/manifold to the exhaust side of the turbo was THE restriction. We have increased the inside diameter in that "penny choke" area resulting in a 50% larger AR, going from .40 to .60. What this means to you is actually faster spool over the V2, which is a-typical with an increase in AR, however the restriction is so bad on the stock frame that this increase means an easier and more efficient path to the turbine wheel. You will also see significant power increases without having to lean on the turbo as much, expect around 30-50whp than a stock turbo at the same boost level. Past the new cast exhaust housing the compressor wheel (inducer/exducer) is 18 percent, and the turbine wheel is 12 percent larger than stock (these remain unchanged from the V2), and finally the wastegate diaphragm is 2psi higher than stock. The dyno graph below represents the same low mileage car with nothing but a tune.  One graph is using the stock turbo, and the other is a couple hours later with a V3 turbo installed. 

11.27.24 Update: Continuing on from the V3.1 we are now releasing the V3.2 version of our 1.4 turbo. We previously had an option for a ported compressor inlet that was done by hand and removed a casting lip, which was good for around 10whp. We have changed our casting to replicate the ported version. Going forward all V3.2's will have this improvement. V3.2's still include the updated bearing structure which has been extremely reliable. We now also include our ZZP billet bypass valve on all V3 turbos for worry free performance. 

11.20.23 Update: Based on customer feedback and testing we have made a rolling change to the bearing structure of the V3. The new center section feature the same wheels but with improved oiling capabilities a brand new internal bearing system, resulting in improved longevity and reliability. 

While the V3.2 is a great stock frame replacement, if you're looking to make even more power on your 1.4 we highly recommend our Z04 turbo kit, found here. 

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. 

Depending on your current setup (mods, available octane, ethanol content, overall power) larger injectors may be required. If you are running the stock injectors, make sure to scan the car to monitor injector pulse width, duty cycle, and air fuel ratio; you will not be able to go very far on stock injectors (without a ZZP tuned FSCM), 42's are suggested for 90% of setups. Tuning IS required for the V3. 

This is a new bolt on turbo, not core based, and it comes with everything needed for the install.

Does not work on Gen 2 (2016.5+) 1.4L Chevy Cruze. 

We do not recommend running our Billet Wastegate Actuator with this turbo.

Your stock drain line is likely frail or may crack during removal of the stock turbo, we sell an upgraded replacement here.

We highly recommend replacing your turbo oil feed line during any turbocharger replacement. We have replacements here. 

Many customers like to do the upgraded bypass valve spring mod at the same time. The V3 has a different tone and pitch bypass sound than the stock turbo, the upgraded spring changes that sound to something more similar to stock. Upgraded spring can be found here. 

Specifications: 

• Compressor inducer: 38.5mm 
• Compressor exducer: 52mm 
  
• Turbine inducer: 43.5mm
• Turbine exducer: 37mm 

Aftermarket bypass valves for the stock turbo WILL NOT fit the V3. 

Continuing on from the great success of our MSD buyback program, Zoom wanted to put another offer out there! Starting now if you own one of our V1 or V2 big wheel turbos for the 1.4, and then purchase our V3 turbo you are eligible for our turbo buy back program. We know those with V1 and V2 turbos are leaving power on the table, and we want to offer a more affordable way to get into a V3. The program works like this: purchase a new V3 big wheel turbo using the same account/email address that you did for your V1/V2. Once you've received your V3 and installed it, return you original V1 or V2 turbo. Ship it back to ZZP after you've received an RMA from customer service and you will receive 100% of your original V1/V2 purchase price in ZZP store credit. This is why you continue to stick with ZZP, no one supports their customers like this. Email customerservice@zzperformance.com if you'd like to start the upgrade/buy-back process. 

Update 11.2024 - V3.2 version released. 
Update 11.2023 - V3.1 version released.
