Characteristics of EA827/EA113 engine
The Volkswagen EA827/EA113 engine, produced at Audi Hungaria Motor Kft., Salzgitter Plant and Puebla Plant, became one of the most popular and recognizable engines of its time. The EA827/EA113 engine brand was on the market from 1983 to 2002, which is a testament to its longevity and popularity. The cylinder block of this engine is made of cast iron, which ensures high strength and durability.
This engine can have either carbureted or injected power system, which allows it to adapt to different operating conditions and requirements. It has an in-line configuration with four cylinders. The number of valves per cylinder can vary from two to five depending on the engine modification. The piston stroke is 86.4 mm and the cylinder diameter is 81 mm. The compression ratio varies from 8.5 to 10, which provides a good balance between power and economy.
The engine has a displacement of 1,781cc, giving it a power output of 68 to 139 hp at revs between 4,000 and 5,800 per minute. Torque ranges from 144 to 168 Nm at 2100 to 4250 rpm. The engine can run on 92-95 octane gasoline. Environmental norms are not specified for this engine.
The weight of the engine is 110+ kg, making it quite light for its class. Fuel consumption in the city cycle is 9.5 l/100 km, on the highway – 6.0 l/100 km, and in the mixed cycle – 7.6 l/100 km. Oil consumption can reach up to 1000 g/1000 km. It is recommended to use oils with viscosity 5W-30, 0W-40 or 5W-40. The volume of oil in the engine is 4 liters, when replacing it is necessary to fill from 3.5 to 4 liters. It is recommended to change the oil every 15,000 km, but it is better to do it every 7,500 km to maintain optimal engine performance. The engine operating temperature is 90 degrees Celsius.
Engine life
The manufacturer does not specify the exact engine life, but in practice it often exceeds 300 thousand km, which confirms its reliability and durability.
Tuning
The EA827/EA113 engine has a great potential for tuning. Power can be increased to 200+ hp without significant loss of life, which makes it attractive to car enthusiasts looking to improve the performance of their vehicles.
Application
The engine has been fitted to a wide range of models across various makes, including the Audi 80, Audi 90, Audi 100, Audi A3, Audi A4, Audi A6, Audi Cabriolet, Audi Coupe, Seat Cordoba, Seat Ibiza, Seat Leon, Seat Toledo, Skoda Octavia, Volkswagen Bora/Jetta/Vento, Volkswagen Golf, Volkswagen Passat and Volkswagen Pointer. This widespread use is a testament to its versatility and reliability.
Reliability and repair of the VW EA827/EA113 1.8 engine
The engine of the Volkswagen EA827 family, 1.8 liter, was released in 1983, and from the younger 1.6-liter motor differs by the increased stroke of the piston. The bottom of the motor is a cast-iron cylinder block, the head was put on 8, 16 and 20 valves, and the latter was produced with a system of changing the phases of gas distribution on the inlet and in the turbo version. On VW engines of this type, with a volume of 1.8 liters, hydrocompensators are installed and valve adjustment is not required. The timing belt drive, belt replacement interval ~60.000 km., when the belt breaks on 8 valve, in most cases, the valves do not bend, on 16 and 20 valve motors bends.
Since 1994, on the basis of this power unit, was created turbo motor – 1.8T, which was widely distributed on Audi, Skoda, Seat and Volkswagen.
Also this motor has kinship with 2-liter 8-valve engines.

Weaknesses of EA113 / EA827, faults and their causes
- RPM problem. Stalling. Check the cushion under the mono injection, coolant temperature sensor, idle valve and throttle valve.
- High fuel consumption. Check the lambda probe and coolant temperature sensor.
- Engine noise. This problem is usually caused by the hydraulic chain tensioner and is solved by replacing the tensioner with the chain.
- Oil leaks. Most likely you have knocked out the oil cooler gasket, change it and the leak will stop.
In addition, constantly clogged and requires cleaning the crankcase gas ventilation system, often fails visco-muff fan, pump and in general, given the age of these atmospheric motors, to fail can be anything and whenever. Summing up it is worth noting In general, the motor is not bad and, with proper maintenance, quite resourceful, but its time has passed and today it is worth looking towards more modern power units.
Tuning of the engine Volkswagen EA113 / EA827
Atmospheric. Turbo
For weak modifications of 1.8 liter Volkswagen engines, the easiest method to increase power is to install a camshaft from more powerful motors like ADZ, ABS and others. In addition, it is worth adding pistons from the same motor and ECU firmware, these manipulations will lead to a small but very sensitive increase in horsepower. Further increase in power, with the help of factory parts, you can continue by installing a 16-valve cylinder-head. If this is not enough, then it is worth buying a sports camshaft with a phase of 270 and more (Autotech for example), put a spider 4-2-1, straight-through exhaust, cold intake and adjust (for example on Yanvar). It makes no sense to build something even more powerful, the motor is old and constant breakdowns will spoil the picture.
It is pointless to turbocharge the motor with turbokit or remake it into a standard VW 1.8T, almost everything will be replaced together with attachments, only the cylinder block with crankshaft will remain native. Much easier and more reliable to buy a contract 1.8 turbo motor and use reliable factory 150-240 hp.
