How to choose

Selecting the right turbo for the BMW 340i 326 hp involves evaluating several key factors, from part condition to compatibility with the vehicle’s existing systems.

1. Check the turbo’s OEM reference against your vehicle’s build code to ensure a perfect match for the N55 engine’s specifications.
2. Verify the remanufacturer’s process, focusing on whether the unit includes a fully refurbished CHRA and variable geometry mechanism.
3. Assess the part’s condition, prioritizing turbos with minimal wear on the compressor and turbine wheels to avoid premature failure.
4. Confirm the turbo’s packaging includes a core deposit label, as this simplifies the return of your old unit for recycling.
5. Evaluate the wholesaler’s stock rotation policy to ensure you receive a unit with recent remanufacturing date for optimal reliability.
6. Review the part’s compatibility with the BMW 340i’s emissions system, ensuring it meets current regulatory standards.
7. Consider the turbo’s warranty terms, which should cover defects but not installation or misuse by a third party.

Storage & logistics

For workshops, storing exchange standard turbos requires climate-controlled conditions to prevent moisture damage to the variable geometry components. Units should be kept in their original packaging until installation, with the core deposit label attached to facilitate returns. Avoid stacking turbos to prevent warping of the housings, and ensure the storage area is free from contaminants like dust or oil residues that could affect the turbo’s performance once installed.
