Opel A20DTR, A20NFT engines
Content
Motors of this model were widely used in the period from 2009 to 2015. They have proven themselves in practice and are an excellent choice as a contract power unit. These are powerful, productive motors that are designed to provide sporty acceleration dynamics and excellent speed performance, high torque and power of cars.
Features of operation of engines Opel A20DTR and A20NFT
The A20DTR is a superior diesel powertrain that delivers fuel economy and low fuel consumption along with high power. The unique common-rail direct injection system significantly reduces response time and improves engine response in practice. The supercharged twin turbo provides the machine with excellent range and the ability to install both conventional and all-wheel drive machines.
A20NFT are turbocharged gasoline engines that were installed to replace the less powerful A20NHT. The main cars that were lucky to get such engines were charged restyled Opel Astra GTC and Opel Insignia models. As much as 280 hp give truly racing dynamics of acceleration and chic opportunities for lovers of dynamic driving.

It should be noted that these power units have significant differences with regards to the working resource. If the A20NFT is only 250 thousand km, then the A20DTR engine can be operated for 350-400 thousand without capital investments and repairs.
Common malfunctions of A20DTR and A20NFT power units
These motors are much more reliable than their predecessors, however, during operation they also have the ability to deliver certain problems to their owners. In particular, the A20NFT engine is notorious for problems such as:
- depressurization of the power unit, as a result of which oil leaks can occur in the most unexpected places;
- the unpredictable resource of the timing belt leads to its breakage and, as a result, bent valves;
- failure of the electronic throttle, which leads to unstable operation of the internal combustion engine and the corresponding message of the on-board computer;
- one of the frequent phenomena can be called mechanical damage to the piston, even with small runs of the car;
For diesel power units, the situation with oil and the timing belt looks the same as for the gasoline counterpart, while problems such as:
- failure of TNDV;
- clogged nozzles;
- unstable operation of the turbine.
These are the most common malfunctions, although they are not so common, motorists should be prepared for similar problems in the operation of the motor.
Each contract engine imported from Europe is most often operated in sparing conditions, on high-quality fuel and lubricants, which allows us to speak of the above breakdowns, rather as exceptions to the rules and special cases.
Applicability of power units A20DTR and A20NFT
The main machines for this type of power units were such machines as:
- Opel Astra GTC hatchback 4th generation;
- Opel Astra GTC coupe 4th generation;
- Opel Astra hatchback 4th generation restyled version;
- Opel Astra station wagon 4th generation restyled version;
- Opel Insignia first generation sedan;
- Opel Insignia first generation hatchback;
- Opel Insignia station wagon of the first generation.
Each unit can be either installed from the factory or act as a tuning option that allows you to increase the power and dynamics of the machine. If you are doing the installation yourself, do not forget to check the number of the power unit with the original one indicated in the documents. In A20DTR diesel engines, it is located behind the armored wires, slightly to the right and deeper from the probe.
At the same time, in A20NFT gasoline power units, the number is located on the starter frame, on the side of the motor shield. Naturally, if the car is already yours and in order not to torment yourself with searches for a long time, you can always find out the engine number by the VIN code of the car.
