Mazda MZR Z6 Engine: Features and Characteristics
The Mazda MZR Z6 engine is one of the popular powertrains found in the Mazda 3 and Mazda 323 models. Manufactured at Hiroshima Plant, this engine combines state-of-the-art technology, high reliability and fuel efficiency, making it an attractive choice for Mazda car owners.
Main Features
The MZR Z6 engine is designed using an aluminum cylinder block for lightness and efficiency. It has an inline four-cylinder design, which is standard for most modern passenger cars. The injected power system provides precise fuel metering, which has a positive effect on fuel consumption and overall engine performance.

Performance
With a maximum output of 105 horsepower at 6,000 rpm and 145 Nm of torque at 4,000 rpm, the MZR Z6 engine provides ample dynamics for city driving and suburban commuting. This engine also meets Euro 4 environmental standards, indicating its low emissions.
Economy
The engine demonstrates good fuel economy, consuming 8.5 liters of fuel per 100 km in the urban cycle, 5.3 liters on the highway and 6.5 liters in the mixed cycle. These figures make it profitable for owners, especially in the face of rising fuel prices.
Maintenance and Service Life
The recommended oil for the MZR Z6 engine is 5W-30, with a full oil change of 4.2 liters and a regular oil change of 3.7 liters. Oil changes are recommended every 7500 kilometers, which helps to keep the engine in good condition. The engine operating temperature is about 90 degrees, which is standard for gasoline engines.
The engine resource according to the manufacturer is not specified, but in practice it can reach about 250 thousand kilometers. This makes it a durable and reliable choice for everyday use.
Faults and repair of the engine Z6 1.6
The Mazda MZR Z6 engine is a development of the B series of motors, specifically, a continuation of the B6D engine, in which the combustion chamber, intake and exhaust ducts, etc. were finalized. The timing system uses a chain, which does not need to be replaced, but it is still worth monitoring the condition, the S-VT inlet timing system, adjustable intake manifold, EGR system, what it is and what it is needed for, to re-run part of the exhaust gases back through the combustion chamber for final afterburning. EGR in no way improves the power performance of the motor and is put solely for the purpose of improving environmental friendliness. According to the idea of designers, the system should bring good to the masses, but given our realities (quality of gasoline), we get only disadvantages in the form of coating the EGR valve with carbon deposits, loose its closure, and over time the valve simply hangs in a certain position, the revs begin to float, the engine Z6 stalls, there is detonation, power loss, etc. Owners of cars with EGR have found a solution to the problem, the valve is simply silenced and that’s it.
On the Mazda 3 1.6 Z6 engine there are no hydrocompensators, once in 120 thousand km. km it is necessary to carry out rather laborious adjustment of valve clearances by selection of glasses. Let’s move smoothly to the faults and problems of the Mazda 3 Z6 1.6 liter engine:
- Swimming revs, the fault is the intake manifold gasket, change the gasket and the problem will go away.
- Vibration of the engine Z6, often the cause of this phenomenon are the engine cushions Mazda 3, which takimi ask for replacement, satisfy their requests, and the problem as a hand will remove.
- The knock in the engine Mazda 3, most often solved by adjusting the valve clearances. Noise can also crank liners and pistons, if such knocks appear, go to the diagnostics and establish the specific cause.
- Diesel sound, knocking, chattering… this is the knocking of the intake manifold flaps, it is repaired or change the manifold.
In addition, the 1.6 liter motor is weak and pulls poorly from the bottom, but otherwise the motor is normal, nothing special, for Mazda 3, a much better choice would be a good 2.0 liter LF.
Engine Z6 1.6 liters is smoothly replaced by more relevant SkyActiv 1.5.
Mazda 3 Z6 1.6 engine tuning
Chip tuning MZR Z6
To calibrate the motor, this is the easiest way to slightly improve the dynamic performance of the car. It should be noted that the engine firmware does not always give visible changes, most often the effect remains at the level of self-influence. Let’s return to the chip, tuners promise about 115 hp after flashing, according to reviews, after chip tuning the difference in dynamics is not felt, which is not surprising… To feel the changes will help us standard set for tuning atmfernka: straight exhaust with a spider 4-2-1, receiver, tuning camshafts for Mazda 3 1.6 and flashing. Chip-exhaust-receiver will allow you to get about 120 hp. Shafts are not easy to find, but making an effort to do it is realistic, everything will depend on the phase and lift, too wide do not need to take, the average phase of 270 +\- optimal for the city.
How else to increase engine power Mazda 3 1.6? Let’s make porting of the cylinder-head, saw intake exhaust channels, put big valves. As a result, after all transformations we will get 140-160 hp at the working volume of 1.6 liters, a pronounced sporty character of the motor and a slight decrease in engine life.
Mazda 3 turbo
A simpler, at first glance, way to get the above-mentioned power on the Z6 engine is to install a turbine. On the Internet you can pick up the necessary turbo kit on Mazda 3 1.6, you need to understand that the standard motor supercharger will not tolerate, and blow below 0.5 bar is ridiculous, so we need a forged piston with counterbores for low compression ratio ~8-8.5, we need good injectors from 2. 3 liter versions, you can not do without a straight-through exhaust, for the full realization of the configuration needs head porting, you need the optimal shafts under the turbine, you need to adjust it … A lot of things to find extremely difficult, and to make to order is expensive and in the end turbo Mazda 3 will cost the price of Mazda 3 MPS, and drive will be worse and much less stable.
