This is our third revision 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 two very similar builds, one on our old V2 and another on our V3; you'll see that even at the same boost level the V3 makes more peak power and torque, as well as a considerable amount of power under the curve. 

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) tuning and 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.

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

A great add-on to the V3 is our Billet Wastegate Actuator, which can be found here.

Big Wheel Turbo V3

Relatively easy install. Only been in the car a week but I do feel a difference in acceleration. So far I'm happy with my purchase. Customer service was outstanding answering any of the questions I asked. Shipping was quick given current world situation.

2012 Cruze V3 Turbo

The performance on the V3 turbo is great. The fitup on my 2012 ECO Cruze with the manual transmission was a challenge. There was interference between one of the transmission mount bolts and the ZZPerformance downpipe that I only resolved by removing the bolt and cutting about 3/8" off of the end. Also, the downpipe sits right against the block web that supports the bell housing. It seems that the overall width of the new turbo assembly is slightly wider. Everything else went together without a problem. I am still working with Tim on the tune but it is working extremely well.

Great product

Installed the new turbo on with easy. Only issue is when installing a blow off valve you will need to shave the sides for it to fit properly. So far she pulls like a champ and can totally notice a difference specially with the catless downpipe. Definitely recommend this an dont forget its gonna need a tune no escaping that.
