Disadvantages of the SR20DET engine
This motor silently travels over 300–350 thousand kilometers if you don’t save on oil;
Cheap oil reduces resources, particularly for the turbine, by clogging the channels;
The timing chain frequently stretches and begins to rattle after 200–250 thousand kilometers; the idle speed controller or mass air flow sensor should be checked for the cause of floating speed;
Wear on the rubber-metal engine mounts is indicated by strong vibrations;
There are frequent leaks from beneath the oil pressure sensor and crankshaft oil seal;
They might not be able to withstand the rocker after heavy use, at which point the engine is over.
