Product Overview
High-Performance GTB1446VZ Turbocharger for Stelvio & Giulia (2.2 Multijet)
- Variable Nozzle Turbine (VNT) Technology: This GTB1446VZ unit features an advanced Variable Geometry system, specifically calibrated for the 2.2L Multijet engine. By adjusting the vane angles in real-time, it provides optimized airflow across the entire RPM range, effectively eliminating turbo lag and providing the sharp, linear acceleration expected from a premium Italian sport sedan or SUV.
- Longitudinal Chassis Optimization: Designed for the 952 (Giulia) and 949 (Stelvio) platforms, this turbo is engineered for a longitudinal engine layout. All mounting points and compressor housing angles are a precision 1:1 match for the CC20 engine bay, ensuring a "drop-in" installation without interfering with the complex cooling and steering components.
- High-Speed VSR Dynamic Balancing: To guarantee long-term reliability and a quiet cabin experience, every core assembly (CHRA) is balanced on a high-speed Vibration Sorting Rig (VSR) at speeds exceeding 150,000 RPM. This process eliminates microscopic shaft oscillations that cause premature journal bearing wear and the high-pitched "VGT whistle" under load.
- Electronic Actuator Synchronization: The unit comes with a pre-installed and factory-calibrated Rotary Electronic Actuator (REA). This ensures perfect communication with the ECU, maintaining stable boost pressure and meeting strict Euro 6 emission standards while maximizing fuel economy during highway cruising.
- Severe-Duty Metallurgy: The turbine wheel is cast from a high-nickel heat-resistant alloy, paired with a precision-machined aluminum compressor wheel. This combination allows for high rotational speeds and rapid spool-up while resisting the thermal fatigue and carbon buildup typical of modern high-pressure common-rail diesel engines.

Q1: Does this turbo fit both the 180HP and 210HP versions of the 2.2D engine?
Yes. For the Giulia and Stelvio 2.2 Multijet platform, the 848460 series turbo is the physical hardware used across several power outputs. The difference in horsepower is primarily managed by the vehicle’s ECU software and fuel mapping. This turbo is a direct hardware replacement for all 2.2D models listed.
Q2: Is the electronic actuator included and calibrated?
Yes, the turbocharger is supplied as a complete assembly with the electronic actuator pre-installed. It is factory-calibrated to the internal VNT vanes. However, we recommend using a diagnostic tool to perform a "Self-Learning" or "Actuator Adaptation" procedure through the vehicle's OBD system after installation to ensure perfect ECU synchronization.
Q3: Why are there so many different part numbers (AD, AE, AB) for the same turbo?
and Mopar frequently update their suffixes (AD, AE, AB) to denote minor production revisions or changes in their supply chain. They are all physically and functionally interchangeable. 04893687AE is one of the most recent supersessions for this GTB1446VZ model.
Q4: What is the most critical installation step for the 2.2 Multijet turbo?
Oil quality and priming. The 2.2 Multijet engine uses very thin oil (0W-20 or 0W-30) for efficiency, which makes the turbo bearings sensitive to lubrication gaps. You must prime the turbo with clean oil before starting the engine and ensure the oil feed filter (if equipped) is clean. We strongly recommend a fresh oil and filter change during installation to prevent soot-contaminated oil from damaging the new VNT mechanism.
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.
