Failure of the pre-turbo or primary turbo actuators, vacuum lines, or solenoids can lead to loss of boost or poor performance.
Oil Metering Pump:
Malfunctions can lead to insufficient lubrication of the apex seals and rotor housing.
Ignition System:
Stock ignition systems can be a weak point; upgrades are common for improved reliability and performance.
