Factory replacement turbos will restore lost power and performance to your turbocharged BMW. If you are experiencing a loss of power, smoking, or wastegate rattle it is a good chance your OE turbos are on their way out.
This is an OEM replacement rear (bank 2) turbo assembly for the S55 engine in the F8X M2 Competition, M3, and M4. This is a new turbo from Mitsubishi, not a rebuilt unit. This is a complete assembly, including the manifold to the engine and the wastegate. Signs of a failing turbo are high oil consumption and blue smoke from the exhaust (not from a leak or failing CCV system) because the internal oil seals are no longer retaining oil. Without critical lubrication and cooling effects from oil, the turbo shafts and bearings are usually the first to wear and that requires a complete rebuild. You might also see increased turbo lag or failure to hold boost, which is usually a sign of a failing wastegate or some other internal issue. With any internal problems, the turbos need to be replaced. This is a new turbo - No core charge.
