Toyota MZ engine

The Toyota MZ engine family is a series of piston V6 engines, the successor to the VZ family and Toyota's second V6 series. It is a lightweight all-aluminium design that uses lighter parts than the heavy-duty VZ blocks, aimed at lowering production cost and reciprocating weight without giving up reliability. Toyota tuned it to be especially smooth at about 3000 rpm, the typical cruising speed on a highway. The block is aluminium with cast iron cylinder liners in a closed-deck layout, with aluminium DOHC cylinder heads, a 60 degree V angle, multi-port fuel injection and four valves per cylinder. The 1MZ-FE replaced the 3VZ-FE as the standard 3.0 litre V6, and the family was later replaced in most markets by the GR series.
