The second generation Opel Zafira was introduced in February 2005 and featured a new platform compared to its predecessor. While most of the engines were new, the top-of-the-line 2.0-liter turbo engine was carried over from the Zafira A. Initially, it produced 237 horsepower. However, a German tuning company has now developed a turbo upgrade kit that significantly increases the power output.

TurboZentrum has developed a Stage 2 turbo kit for the Opel Zafira’s Z20LEH four-cylinder engine. The main difference compared to other kits for this engine is the new and optimized size and shape of the compressor wheel. TurboZentrum has designed the kit specifically for the airflow and exhaust specifications of the 2.0-liter turbo engine. The result is an impressive increase in power.

With the turbo upgrade kit, the peak output of the Zafira OPC now reaches 400 horsepower, and the power curve is flatter compared to the stock engine. Additionally, the new turbocharger delivers the same levels of air mass as the stock turbo but at a lower turbocharger speed, reducing the load on the turbo and improving its longevity.

The price of the turbo upgrade kit is $1,972 (1,844 Euros), and there is also a Stage 1 turbocharger available for $1,495 (1,398 Euros). The same engine can also be found in the Opel Astra OPC, allowing for the same performance upgrade in the hatchback variant.

It’s worth noting that the second-generation Zafira was the last to offer an OPC version. The third-generation model was equipped with smaller turbocharged gas engines and a more powerful twin-turbo diesel engine. Opel has since discontinued the Zafira and now uses the name for a slightly larger commercial vehicle, which is also available with a fully electric powertrain called the Zafira Life.
