Frequently Asked Questions
The STC99N turbocharger assembly uses exhaust gas energy to drive a turbine that compresses intake air for the 2.5L 4-cylinder turbo diesel engine. Increasing the intake charge raises the mass of air entering the cylinders, allowing a greater fuel charge and producing higher torque at lower engine speeds. The assembly includes turbine and compressor housings, a rotating shaft and bearing system; correct mounting and secure connections to the engine oil supply, exhaust and intake pipework are required for reliable operation.
