Toyota designed and manufactures the MZ engine family. Some of the variants are still in production. They are V6 engines, have DOHC [double overhead camshafts] and make use of aluminum alloy engine block and heads. Toyota produces # 3 MZ engines. We have all three variants, the 3MZ-FE, the 2MZ-FE and the 1MZ-FE Toyota engine for sale.
The 1MZF-E engine is a 3 Liter is designed for good fuel economy without a performance drop. Using light weight parts such as aluminum as a replacement for cast iron helps to reduce weight, and the power needed to push the vehicle. Use of lightweight materials is one way to increase performance and economy in an inexpensive manner.
Certain high temperature plastics are used for intake manifolds as opposed to cast iron and aluminum. Ease of manufacturing is one reason they use plastics, and reduced weight as I mentioned already. The issue is more of how not to increase the weight of a car. With all of the add on luxuries and sound deadening insulation, finding ways to simply not increase weight is the challenge.
The 1MZ-FE with VVT-i is used in the Avalon, Highlander, Sienna and Camry. Output is 210 hp. Early versions of the VVT-i 1MZ used a dual throttle body, cast aluminum intake manifold, and EGR block off plates on the exhaust manifolds. As mentioned, later versions used an ABS plastic intake manifold to further weight reduction and decrease cost.
Toyota Racing Development [TRD] offered a bolt-on supercharger kit for the 1997–2000 Camry, 1998–2000 Sienna and 1999–2000 Solara. Power output jumped to 242 hp. The engine is structurally very strong to accept a turbocharger without additional design upgrades.
My suggestion for replacing an MZ engine would be to see if a used engine suits your needs. First off, they are available as JDM used engines. Engines from the Japanese Domestic Market are very appealing. The reasons are as noted. JDM engines come from low mileage [approx. 40,000 miles] cars from Japan. Here is a good article if you want details on why JDM engines are available in America.
JDM engines are my first recommendation for a Foreign car. We sell rebuilt engines and crate new engines too. You make the final choice, we provide the materials needed for you to make an educated decision. Call now and speak with a trained sales representative about how we can fill your needs.
