FAQs

Q1: How do I know if my engine is QSB Tier-2 or Tier-3? 

Please check your engine's Data Plate. Tier-3 engines typically have a different fuel injection system and turbocharger configuration. To ensure 100% fitment, matching the part number 4042715 from your existing HE221W nameplate is the best method.

Q2: What is the difference between HE221W and HE200WG? 

While they may look similar, the HE221W often features different flange dimensions and internal specs optimized for the Tier-3 QSB power curve. Using the incorrect model can lead to poor fuel economy and high EGTs (Exhaust Gas Temperatures).

Q3: Does this unit include the wastegate actuator? 

Yes. This is a complete turbocharger unit including a pre-set and calibrated wastegate actuator, ready for immediate installation.

Q4: What are the installation tips for industrial QSB engines? 

Because industrial engines often operate in dusty environments, we strongly recommend replacing the Air Filter and cleaning the Intercooler during installation. Always pre-lube the turbo with fresh oil through the oil inlet before starting the engine.

Q5: Do you provide worldwide shipping? What is the delivery timeframe? 

We ship globally via premium carriers like DHL, FedEx, and UPS, as well as sea freight for bulk orders. In-stock items are typically dispatched within 24–48 hours. Express delivery to North America and Europe usually takes 5–7 business days.
