Suzuki H27A engine
The Japanese automotive industry is one of the best in the world, which hardly anyone can argue with. Among the many concerns, both average manufacturers of automotive products and clear leaders in the field stand out.
Perhaps Suzuki can be attributed to the latter. Over its long history, the automaker has produced a huge number of units, among which it is simply impossible not to single out motors.
Today, our resource decided to consider in detail one of the Suzuki ICEs with the name "H27A". Read about the concept, the history of the engine, its technical characteristics and operation features below.
Creation and concept of the motor
In the late 80s of the last century, Suzuki took seriously the expansion of its model lines. Deciding to move in step with the times, the concern designed and actively began to produce at that time new, unusual crossovers for everyone. One of the first representatives of this type of machine from the manufacturer was the well-known "Vitara" (in Europe and the USA - "Escudo").
The model was received so well by the automotive community that it has been produced since 1988 to this day. Naturally, during its existence, the crossover has succumbed to not a single restyling and technical update.
The “H27A” motor considered today is a representative of the “H” motor series specifically for Vitara. These engines appeared 6 years after the start of crossover production.
The "H" series motors became a kind of transitional link between several generations of power plants and acted as an excellent replacement for the main Suzuki ICE. They were produced for a little over 20 years - from 1994 to 2015. In total, there are three units in the H engine series:
- H20A;
- H25A and its variations;
- H27A.
The latter is the most powerful representative of the line and, similarly to its counterparts, was installed only in the crossovers of the Vitara lineup, as well as in a limited series in the XL-7 SUVs. It should be noted that the concept of H-motors is a joint development of Suzuki, Toyota and Mazda. If the last two concerns continued to modernize fairly good internal combustion engines, then Suzuki abandoned this idea and did not create anything based on the H series units.
The H27A is a 6-cylinder V-engine with a 60-degree angle. At the time of its inception, it was built using innovative aluminum ICE construction technology using a double camshaft.
Naturally, now it does not surprise anyone. The DOHC gas distribution system is used everywhere and 4 valves per cylinder is the norm. Despite the innovation and novelty, the H-series motors turned out to be very good and have a positive feedback base. All owners of the units note their good functionality and high level of reliability.
The H27A does not have any significant features from similar V6s.
The power system of the H27A is a typical injector with multi-point fuel injection into each of the cylinders. These units run on gasoline and were produced exclusively in atmospheric versions.
As noted earlier, only Suzuki's Vitara crossovers and XL-27 SUVs were equipped with the H7A. Engines were produced in the period from 2000 to 2015, so it is not difficult to find them both in the form of a contractor and in the form of an already installed unit in a car.

Note! Suzuki engines with the name "H27A" were produced exclusively in the aspirated version with the characteristics noted above. It is pointless to look for more powerful or even turbocharged ICE data samples in stock. They simply don't exist.
Repair and service
The H27A is one of the most reliable V6s of its generation. Reviews from the operators of these units are positive. According to the responses of H27A owners and car repairmen, the motors have an excellent resource and are practically devoid of typical malfunctions. More or less often, H27s have:
- noise from the timing;
- grease leaks.
The noted problems are solved by a major overhaul of the engine and often appear with a run of 150-200 kilometers. By the way, there is nothing difficult in servicing the H000A. They are engaged in any service stations throughout the entire post-Soviet space. The design of the units is simple and typical for the "Japanese", so car craftsmen are happy to take on their repair and do not put huge prices on it.
Despite the positive picture regarding the operation of the H27A, one cannot fail to note its weak link. No matter how strange it may sound, but it is the gas distribution chain. If on most engines it needs to be replaced every 150-200 kilometers, but on H000s - 27-70. This is due to the specific design of the engine oil system.
There is no need to go into the details of its consideration. The only thing to note is that the cross section of the oil channels is too small. With their slightly larger size, the timing chain would have a standard resource for motors and would not require such frequent replacement.
In other aspects, the H27A is more than reliable and rarely causes problems for its exploiters. This state of affairs is confirmed by practice and is beyond doubt.
Tuning
Fans of Suzuki products rarely resort to upgrading the H27A. This is due to the highest resource of ICE data, which motorists do not want to lose due to tuning. If reliability is the parameter that you specifically neglect, then in the design of the H27s you can:
- carry out turbocharging by installing a moderately powerful supercharger;
- slightly improve the fuel injection system;
- to strengthen the cylinder-piston group and the gas distribution mechanism.
Having reinforced the modernization noted above with chip tuning, stock 177-184 "horses" will be able to spin up to 190-200. Note that when tuning the H27A, it is important to be prepared for the loss of a resource. On average, it falls by 10-30 percent. Is it necessary to risk the level of reliability of the motor in order to increase its power? The question is not easy. Everyone will answer personally.
