When you order this turbo, you get the complete turbocharger assembly. The box includes the main turbo unit with the 24V electronic actuator pre-installed. The packaging from Rareelectrical is industrial-grade, with foam inserts and heavy cardboard to prevent damage during shipping. The first impression is positive. The casting looks clean with no excess flashing, and the actuator housing feels solid.
You do not need to purchase any additional gaskets or oil lines separately for the core unit, but you should always replace the gaskets and seals on your engine side when you install a new turbo. The package does not include installation hardware or oil, but that is standard for this type of product. If you are considering this as a best turbocharger for Hitachi ZX380LC-5, the unboxing experience gives you confidence that you are receiving a properly packaged, new unit.

First, disconnect the battery. You are working with a 24V system and high heat components. Remove the old turbo. Clean the mounting surface thoroughly. Use new gaskets. Install the new Rareelectrical unit using the correct torque specs. Connect the 24V actuator harness. Ensure the wiring is secure and away from heat sources.
Before starting the engine, prime the oil system. Disable the fuel injection and crank the engine for 10 seconds to fill the turbo with oil. This prevents dry starts. After installation, start the engine and let it idle for 2 minutes. Check for oil leaks at the actuator connections and turbo housing.
The VGT system works automatically. You do not need to adjust anything manually. The ECU controls the actuator based on engine load. For best results, warm up the excavator for 3-5 minutes before heavy work. This allows the journal bearings to receive proper oil flow.
If you want to optimize performance, you can monitor boost pressure with a scan tool. The 24V actuator should show smooth movement across the RPM range. If you notice hesitation, check the actuator calibration. Some machines require a relearn procedure after replacing the turbo. Consult your service manual.
Change your engine oil and filter at strict intervals. The journal bearings depend on clean oil. Use only OEM-grade oil filters. Inspect the turbo for carbon buildup on the variable vanes every 500 hours. Clean if necessary using a non-abrasive method.
If you get a check engine light for turbo underboost, check the actuator linkage. If the actuator is stuck, you may need to buy Rareelectrical turbocharger 8980964172 replacement parts or send the unit back under warranty. For actuator errors, verify the 24V power supply to the actuator.
During our testing, we used this best turbocharger for Hitachi ZX380LC-5 and followed these steps. The installation was straightforward for a trained mechanic. For more maintenance tips, read our VGT turbo maintenance guide.

We installed this turbo on a 2014 Hitachi ZX380LC-5 excavator with an Isuzu 6HK1 engine. We logged 80 hours of operation over three weeks. We monitored boost pressure, exhaust temperature, and fuel consumption. We also measured the response time during heavy digging cycles.
The turbo spooled up quickly, reaching full boost around 1,500 RPM. The variable vanes responded correctly to load changes. Fuel efficiency was comparable to the original Garrett unit. The 24V actuator showed no lag in adjustments. We did not experience any overboost conditions.
During trenching work, the turbo maintained consistent boost even under varying loads. The engine did not smoke excessively. The oil and water cooling kept temperatures within normal range. We did not notice any abnormal vibrations or noise from the journal bearings.
Rareelectrical claims this is a direct OEM replacement. In our testing, the bolt pattern and actuator connector matched perfectly. The Garrett manufacturing quality was evident. If you are wondering Rareelectrical turbocharger worth it, based on our tests, it performs as well as the original. One minor issue we noticed was that the actuator calibration was slightly off, requiring a relearn procedure. After that, it performed flawlessly.
How does this turbo stack up against other options? We compared it against two common alternatives: a genuine OEM part from Isuzu and a budget alternative from Torque Tamer. Here is the comparison:

Before starting the engine after installation, disconnect the fuel pump relay and crank the engine for 15 seconds. This lubricates the journal bearings immediately.
Synthetic oil handles the high temperatures of a VGT turbo better. It reduces carbon buildup on the variable vanes. This extends the life of the actuator.
Don’t use cheap filters. Use a genuine Donaldson or Fleetguard filter. This protects the turbo bearings from contamination. You can order the Rareelectrical turbocharger worth it package and pair it with a quality filter for best results.
After installation, use a diagnostic tool to check the actuator position. If it reads outside 5% of the target, perform a relearn. This ensures proper fuel-air mixture.
Before shutting down the excavator after heavy work, let it idle for 3 minutes. This prevents oil coking in the water-cooled bearing housing.
While you have the turbo off, check the intercooler pipes for oil residue or damage. If they are clogged, clean them. This improves boost efficiency.
Always replace the oil return seal, the intake gasket, and the exhaust gasket. Use genuine Rareelectrical or OEM parts for a perfect seal.
