Garrett Models Explained
GT Models use a new naming system. The new system was introduced as an easier identification of the turbo's characteristics.
New models can have up to 10 digits, that specify its range, measurement of the compressor wheels and the rest of the turbo's characteristics. The old naming system is obsolete.
Example
