Verify your specific engine code, production year, and OEM reference numbers before ordering. Confirm that the backplate and shaft dimensions match your existing compressor housing to ensure proper assembly during rebuild.

Technical Notes

The S1B turbo model is a fixed-geometry design, meaning it does not use variable turbine nozzles. This core is a standalone CHRA unit; it does not include the compressor or turbine housings. Before installation, verify the backplate bolt pattern and shaft alignment against your existing housing. Confirm the actuator rod length and spring rate match your original component to maintain correct boost pressure. Ensure the core dimensions align with your specific application to prevent assembly issues during rebuild.
