This is a replacement turbo with a larger compressor wheel that will drop in place of your OEM turbo. No physical modifications needed.
The factory turbocharger found in LTG powered vehicles is manufactured by Mitsubishi with a 46mm x 58mm compressor wheel. This means that the inlet of the wheel has a 46mm diameter, and where the air exits the wheel into the compressor housing, the wheel diameter is 58mm. The factory turbo does a great job of responding quickly and efficiently for a daily driver car running in the 275 to 325 horsepower range. However, many people are looking to get more power out of their 2 liter ATS, Camaro, CTS, Regal, or Malibu.
If our ZFR line of bolt on turbos don’t match your budget or power goals, we now offer factory turbochargers that have been modified with our larger billet compressor wheel.
The new wheel measures 50mm at the inducer and 64mm at the exducer diameter. Adding more diameter to the exducer changes the characteristics of the wheel in a way that adds efficiency at higher boost levels. This makes our Big Wheel turbo for the LTG an excellent choice for people looking to run over 20psi boost pressures. On our 2014 manual trans Cadillac ATS sedan, we have actually surpassed 360 horsepower to the wheels with our Big Wheel Turbo. Of course this is with all of our LTG bolt on modifications that we sell, and running on E85.
Does not come with PCV inlet tube, bypass valve assembly, or wastegate actuator. Those items will have to be swapped over from your stock turbo.
This is a brand new OEM turbo machined for the larger wheel, and no core charge is required.
Supply is limited.
