A16LET engine

Four-cylinder internal combustion engine. Engine power is 180 hp. (132 kW) with an engine capacity of 1598 cu. sm (1.6 liters)

The A16LET engine is equipped with a K03 turbocharger which can provide adequate air mass for 34+ Kgm and 240+ Hp.

However the engine’s internal parts cannot withstand this level of stress.

In order to take advantage of the maximum reliable turbochargers air mass provision and to perform the maximum possible power it is essential to replace the engine’s internal parts to ensure the engine’s reliability.

Z16LET engine was throttled by the Euro 5 environmental requirements and was called A16LET, actually, this is the difference between A16LET and Z16LET, which comply with the Euro-4 requirements.

In 2012, Opel has replaced it with the A16XHT engine, very modern, more torque, and in general, a better engine.

Opel Astra 1.6 Turbo Chip-tuning

You can change the whole outlet on the direct flow pipe at 63 mm (no sense in installing bigger), acquire cooler kit on Astra 1.6, chip it and get about 230 hp.

Of course, you can tie KKK K04 from Astra J OPC or Garrett 28, forged pistons to deliver, set up and blow all the money, but then you need to think about the transmission, suspension, brakes, ie, require revision as a whole, it is expensive and is not rational, it is easier to acquire initially rapid Astra OPC and refine it.
