Holset HE221 Turbocharger


A genuine Holset HE221 turbo designed for high efficiency and strong top-end performance in compact diesel builds. This model is widely favored for OM605, OM606, and OM662 super-turbo applications, as well as custom projects where rapid spool and increased airflow are desired. Featuring a small-frame design with exceptional flow characteristics, the HE221 is a popular upgrade for tuners seeking more power than typical stock-size turbos can deliver.

This unit uses a T25 turbine flange, making it ideal for custom manifold setups or adapter use on engines originally equipped with T3 housings.

Specifications

  • Model: Holset HE221

  • Exhaust Flange: T25

  • Compressor & Turbine: High-flow compact design

  • Wastegate: Integrated wastegate assembly (varies by actuator style)

Important Notes

No backplate included — users must source or fabricate one for installation.
Compressor outlet uses a unique flange — unlike other Holset units, an adapter or correct flange must be acquired for proper fitment.

Performance Characteristics

✔ Efficient, high-flow turbo in a compact size
✔ Excellent spool with strong mid/top-end power
✔ Popular for custom performance builds
✔ Suitable for both mechanical and EDC setups when properly matched to fueling

This turbo is most effective when paired with larger injection pump elements or tuned electronic fueling, as stock fueling will not fully utilize its potential.

Best For

  • OM605 / OM606 / OM662 turbo builds

  • Custom welded or adapter manifold applications

  • Higher-power daily builds or competition setups

  • Super-turbo compound systems

    Ma BMW roulait mal jusqu’à ce que j’achète ce nouvel amortisseur et amgcarpartsforsale avait exactement la pièce d’origine que je voulais, donc les bosses sont à peine perceptibles maintenant et l’habitacle est calme.
