What is the primary benefit of the billet compressor wheel?

The billet compressor wheel is machined from a solid piece of aluminum, which makes it stronger and more durable than cast wheels. It also allows for more intricate blade designs that can improve airflow efficiency and boost response.

What does the .90 A/R ratio on the turbine housing mean?

The A/R ratio (Area/Radius) on the turbine housing indicates its size and how quickly it can spool. A .90 A/R is a moderate size that generally offers a good balance, providing strong performance in the mid-range RPMs while still allowing for significant power at higher engine speeds.

What other modifications might be needed when installing this turbocharger?

Installing a larger turbocharger like this often requires supporting modifications. This can include upgrades to the fuel system, intake piping, exhaust system, and potentially engine tuning to safely manage the increased airflow and power.
