Our MW2 turbochargers use the latest advancements in wheel blade geometry to make the most possible flow within the stock housings. They provide great street and race drive-ability with a snappy throttle response and a top end that pulls hard all the way to redline. 

This kit starts with the OEM turbo, then we CNC machine the compressor cover and turbine housing to make room for the enlarged compressor and turbine wheels. Other companies only touch the compressor side, but we know that won’t provide the power and drive-ability that everyone desires. 

Next, we machine the compressor wheel from forged aluminum with a 6+6 blade layout for optimal flow. We the incorporate a 713c nickel-chromium inconel turbine wheel to handle all the abuse we can throw at it. We pair both wheels with brand new OEM bearings to complete the CHRA. Each turbo is then professionally assembled, balanced and quality inspected to make sure you are getting perfect units for your vehicle. 

On pump 93oct, intake, 50/50 methanol and downpipes we are showing 736whp.  These turbos are consistently holding 28psi with much more headroom to spare. We expect much more power with additional fueling support and ethanol blends.


Each kit requires a core exchange. You can select to mail your turbos (2 OEM required) first or pay a the core exchange fee of and receive a refund less 3% upon receipt of your exchange. The turbos that are exchanged must not be damaged and in working order.
