Cartridge Compatibility and Installation

This product includes the assembled turbocharger center section and the installation items listed under What’s Included. Reuse the original GTP38 compressor and turbine housings; the outer housings and turbo pedestal are not included. Inspect the housings for cracks, wheel-contact damage, and other defects before reuse. Confirm the original turbo is the early-1999 GTP38 configuration. A 1999 model year alone does not distinguish it from the later design.

Replacement cartridge for the factory Garrett GTP38 turbocharger. Also fits the SPOOLOGIC Stock Turbocharger — SL-100-004.

Keep the rotating assembly intact to preserve its balance. Do not loosen the compressor-wheel nut. The supplied CHRA requires no internal rebuild before installation.
