What is the A/R ratio on the turbine housing and why does it matter?

The A/R ratio on the turbine housing is .85. This number relates to the housing's size and shape, affecting how quickly the turbo spools up and how much power it can make at higher RPMs. A .85 A/R generally offers a good balance for performance applications like this.

Does this turbo kit come with all the necessary installation hardware?

The product listing does not specify if all installation hardware is included. It is recommended to consult the manufacturer's installation instructions or contact ATS Diesel directly for a complete list of included components and any additional parts you might need.

Can this turbo kit be shipped to California?
