Toyota MZ engine
The Toyota MZ engine family is a piston V6 engine series. It was the successor to the previous VZ engine family, and was Toyota's second V6 engine series. It is a lightweight V6 engine of an all-aluminium design, using more lightweight parts than the previous heavy-duty VZ block engines in an effort to lower production costs and decrease engine and reciprocating weight without sacrificing reliability.
Toyota sought to enhance the drivability pattern of the engine (over the 3VZ-FE) at exactly 3000 rpm, since that was the typical engine speed for motors cruising on the highway. The result was less cylinder distortion coupled with the decreased weight of rotating assemblies, smoother operation at that engine speed, and increased engine efficiency.[citation needed]
The MZ series has an aluminium engine block and aluminium alloy DOHC cylinder heads. The cylinders are lined with cast iron, and is of a closed deck design (no open space between the bores). The engine is a 60 degree V6 design. It uses multi-port fuel injection (MFI), four valves per cylinder, a one-piece cast camshaft and a cast aluminium intake manifold.
This engine has been phased out in most markets, replaced by variants of the then-new GR series.
The 1MZ-FE is a 3.0 L (2,994 cc) dual overhead cam (DOHC) V6 engine, replacing the 3VZ-FE as the standard 3.0 L V6 engine in North America and later worldwide. Bore and stroke is 87.5 mm × 83 mm (3.44 in × 3.27 in). Output is 194–201 hp (145–150 kW; 197–204 PS) at 5,200–5,400 rpm with 183–209 lb⋅ft (248–283 N⋅m) of torque at 4,400 rpm. Horsepower ratings dropped after the Society of Automotive Engineers (SAE) implemented a new power measurement system for vehicle engines; Toyota engines rated on 87 octane dropped the most, compared to the same engines used by Lexus rated on 91 octane. It has bucket tappets and was designed for good fuel economy of 19 mpg‑US (12 L/100 km; 23 mpg‑imp) city and 25 mpg‑US (9.4 L/100 km; 30 mpg‑imp) highway without an overall performance trade-off.
Toyota Racing Development offered a factory supported bolt-on supercharger kit for the MY1997–2000 Camry, MY1998–2000 Sienna and MY1999–2000 Solara in North America. Power output was bumped to 242 hp (180 kW; 245 PS) and 242 lb⋅ft (328 N⋅m) of torque.
The 1MZ-FE was on Ward's 10 Best Engines list for 1996.
