MuchBoost A20DTR BiTurbo Upgraded Turbochargers with a Custom Billet Compressor Wheel 6+6 Blades, and Clipped and Lightned/Enlarged High-Flow 9 Blades Turbine Wheel. They are based on original BorgWarner turbochargers, which means that the installation is 100%P&P. The turbocharger is meant to work with Opel Insignia I, Astra J, Cascada I, Zafira Tourer C, and Saab 9-5 II with an A20DTR Bi-Turbo engine.

The turbo delivers up to 173% power (140 extra HP) over the factory specs. It is a great choice for someone looking for a bit extra HP from their daily driver. MuchBoost turbo allows you to get more from your engine and enjoy it even more than you’ve been so far.
