FAQ

Q1: Is this turbocharger a direct replacement for my original Mitsubishi part?
Yes, this GT1749V unit is designed as a direct OE replacement. It matches the physical dimensions, flange pattern, and oil/coolant line connections of the original Mitsubishi turbo. However, we strongly recommend comparing the actuator orientation and part number (21178113) with your removed unit before installation.

Q2: What maintenance is required after installing a new turbocharger?
Crucial steps include: 1) Replacing the engine oil and oil filter. 2) Cleaning or replacing the air filter. 3) Priming the turbo with clean engine oil before starting (disconnect the fuel pump relay and crank the engine for 10 seconds). 4) Allowing the engine to idle for 2-3 minutes after a heavy load to cool the turbo bearing. Failure to follow these steps can lead to premature bearing failure.

Q3: What should I do if the boost pressure is too high or too low after installation?
First, check for boost leaks in the intercooler piping and hoses. Second, verify the wastegate actuator rod length and vacuum/pneumatic signal. If the actuator is adjustable, it may need calibration to the factory specification. For VGT turbos, ensure the electronic control module (ECM) or vacuum line is functioning correctly. If issues persist, the turbo may need professional diagnosis for internal bypass valve function.
