If you own a 2008-2009 Caliber SRT-4 and want to do a turbo upgrade for more power, read on!

AGP's Big Wheel Stocker uses your existing factory cast iron turbofold to replace the OEM turbo cartridge with a larger intake compressor wheel and exhaust wheel. You get the benefit of a stock looking turbo that easily bolts on, and uses all of your existing intake piping and turbo outlet piping.

With AGP's BWS larger compressor and exhaust wheel, your engine will move greater volumes of air, creating more horsepower! You can install this turbo with no tuning, however its strongly recommended you have a air fuel mixture ratio gauge to monitor your engine and make sure you aren't running lean. For maximum power gains, we recommend you use a Diablosport tuner, and contact a custom tuner to create a custom tune for more boost and adding fuel.

Its been our experience that with BWS turbo's, generally an additional 35-50 horsepower can be made over peak stock turbo levels.

Compressor Sizes:

This unit is bought outright, you do not need to send your old turbo in for a core. 

This turbo does not come with a turbo diverter valve, or wastegate actuator, so you can transfer over your existing ones to this turbo.
