Would you like to gain over 220HP extra from your engine? Does it feel like your car could do more? You are not wrong, MuchBoost has got a solution just for you.

MuchBoost B57D30 3.0 Hybrid Upgraded Turbochargers with Custom Billet 7+7 Compressor Wheels and a High Flow 9 blade Turbine Wheel. They are based on original KKK (BorgWarner) turbochargers, which means that the installation is 100% P&P. The turbocharger set is meant to work with BWM 540d, 740d G11, 640d G32, X3 G01 M40d, X4 G02 M40d, 840d G15, and M340d G20 Bi-Turbo equipped with the 3.0 B57D30 320-326HP engine.

Our Hybrid Turbocharger allows your car to feel more agile and sporty. It is a great choice for someone looking for a quick daily driver with more power. Our Turbo allows you to get 172% (230 extra HP) more power than the stock figures.

Please be aware that this offer refers to a Just Upgrade option. That means that you will have to send us your turbos in order for us to be able to work on them! The VNT must be in good condition.
