This is our entry level Low Pressure 6.4 turbo on the market.  This is meant for tow rigs, stockish trucks, and guys who never plan on upgrading to larger injectors.  We spent years testing, modifying and trying all the different options currently out there and then we blew them out of the water.  This is the ONLY turbo on the market with a 4" larger inlet with ported anti-surge cover, and larger 360 thrust bearing.

This may be our entry level towing turbo meant for stock injectors, but it still outperforms most other options on the market unless you go much bigger.
