How to Use the ATG

It is important to understand that using the vehicle application guide to select the correct OEM replacement turbo is only accurate approximately 80% of the time. OEM turbochargers constantly evolve for improvements in both durability and performance and can change in mid-year production. The best way to ensure you have the most accurate and up-to-date replacement turbo is to use the part number cross-reference. Identify the turbo part number of the unit you are replacing (see Nameplate Guide on Page 1) and use the correct ATG application section and cross-reference to verify the proper replacement turbocharger. If your current supplier does not use the correct OEM replacement number you have no way of knowing if you are using the most up-to-date replacement unit. Automotive turbos are frequently not available as remanufactured due to the extreme temperatures and high rotational speeds seen in operation. However, in a few applications, remanufactured turbochargers are safely available. If your application has a reliable remanufactured unit available, it will be shown in the ATG.
