Attention: Factors for the Proper Operation of the Turbo

a) This turbo requires a larger cold air intake to operate efficiently.
b) An intercooler capable of handling higher airflow than the turbo's output is necessary.
c) Oil pressure must be maintained at 5 bar.
d) Proper ECU tuning is critical for performance and reliability. Correct tuning prevents the throttle valve from closing, ensuring smooth operation.
e) The catalytic converter must support more horsepower than the turbo produces. Typically, a metallic catalytic converter with 100 cells is recommended. The exhaust system specification is optional but should match the turbo's capacity.
f) The quality and condition of the oil must meet high-performance standards.
g) It is essential to regularly check the air pressure system, maintaining at least 2 bar, to avoid turbo overspeed.
h) A mechanical blow-off valve is recommended, as factory-installed valves may fail to close properly, leading to turbo overspeed.
