From Wikipedia, the free encyclopedia
The Toyota MZ engine family is a V6 piston engine series. The MZ series has an aluminum engine block and aluminum DOHC cylinder heads. The cylinders are lined with cast iron. It uses Multi-fuel injection(MFI), has 4 valves per cylinder and features a one-piece cast camshaft and cast aluminum intake manifold. The MZ family is a lightweight V6 engine of an all aluminum design, using lighter weight parts than the heavier duty VZ block engines in an effort to lower production costs, decrease engine weight, and decrease reciprocating weight without sacrificing Toyota reliability.
They feature cast aluminum pistons with valve reliefs, and a coating. Normal rings, lighter weight rods, and a forged steel crankshaft.
